MESA 16.x Release Notes\n\n\n\n\n\n\n\n\n\n<\/p>\n\n\n\n

Welcome to MESA Version 16.3.  There are a few \nimportant changes (highlighted in red) that you should read.   <\/p>\n\n\n\n

1. There are some database format changes for \nMESA Version 16.2 projects.  Once a project has been saved in Version 16.2 you \nshould not re-open projects in earlier versions of MESA or you will risk \ncorrupting your projects.<\/p>\n\n\n\n

2. The colorscales and configuration files are \nnow installed in C:\\ProgramData\\GreenMountain\\colorscales and \nC:\\ProgramData\\GreenMountain\\config respectively.  The first time that MESA 16.2 \nis launched, the user preferences will be updated to point to the new colorscale \nand configuration file directories.  If you have custom colorscales or \nconfiguration files, you can either reset the user preferences to their previous \nlocations or you can copy your custom files to the new directories. <\/p>\n\n\n\n

3. The release notes will appear when you start \nMESA as long as Display Release Notes on Startup is set to Yes in the user preferences<\/a>.  \nThe user preferences are also used to set the default data directory for MESA \nprojects.<\/p>\n\n\n\n

Version 16.3.5 Enhancements and \nFixes<\/p>\n\n\n\n

1. Fixed an issue with the calculation of inverse templates \n(sources firing into a given receiver).  This solved potential problems \ntransferring MESA geometries to Gator.<\/p>\n\n\n\n

Version 16.3.4 Enhancements and \nFixes<\/p>\n\n\n\n

1. Improved the performance of the Bin Attribute Analysis \nwindow.<\/p>\n\n\n\n

2. Fixed multiple issues with elevations, shot depths, receiver \ndepths, and water depths when exporting marine geometries to SPS.<\/p>\n\n\n\n

Version 16.3.3 Enhancements and \nFixes<\/p>\n\n\n\n

1. Fixed an issue with inverse templates not exporting to Marlin \nproperly.<\/p>\n\n\n\n

Version 16.3.2 Enhancements and \nFixes<\/p>\n\n\n\n

1. Added an option for decimating hydrophone positions in the \nP1\/90 offshore export.<\/p>\n\n\n\n

2. When importing xy-coordinate information from external ASCII \nfiles, there is now an option to handle situations where the file is missing \ncoordinate data for one or more stations.  You now have the option to \ntemporarily assign a coordinate of (0,0) for any missing data in the file \ninstead of simply cancelling the import.<\/p>\n\n\n\n

3. Fixed a display issue in Edit Templates mode in which the last \nsource in the project could not be selected to view its template.<\/p>\n\n\n\n

4. Fixed a problem reading in P1\/90 files from simultaneous \nshooting geometries.<\/p>\n\n\n\n

5. Fixed an issue with the persistence of the number of station \nnumber digits when exporting MESA geometries to SimSurvey and Marlin.<\/p>\n\n\n\n

6. Fixed a problem with the calculation of hydrophone positions \nwhen creating towed steamer geometries by shooting existing marine sail \npolylines.<\/p>\n\n\n\n

7. Fixed an issue in which some source points weren’t getting \nre-assigned cable configurations when re-shooting existing marine surveys.<\/p>\n\n\n\n

8. Added the numbering options dialog box to the marine sail line \ngeneration tool.<\/p>\n\n\n\n

9. Added an option to the SEGP1 and SPS export dialog boxes for \nresetting the filename prefix to the name of the currently loaded database. <\/p>\n\n\n\n

Version 16.3.1 Enhancements and \nFixes<\/p>\n\n\n\n

1. Fixed a problem loading pre-version 16 MESA databases as \nadditional projects.  There was an inconsistency with the format of the stored \ndatum transformation which prevented additional projects from being loaded \nsimultaneously.<\/p>\n\n\n\n

2. Added the run in\/out capability for geometries created using \nmarine sail polylines.<\/p>\n\n\n\n

3. Rotation\/translation functions are now accessible prior to the \ncreation of sources and\/or receivers.  Previously, a project needed sources or \nreceivers for the translation options to be active.<\/p>\n\n\n\n

4. Added support for reading receiver attributes from Gator \nversion 2.0 MFA files.<\/p>\n\n\n\n

5. Fixed an issue launching SimSurvey when special characters are \nincluded in the path name.<\/p>\n\n\n\n

Version 16.3.0 Enhancements and \nFixes<\/p>\n\n\n\n

1.  MESA now includes WMS data from OnTerra-MapSavvy.  This \nservice includes Bing Maps and Here Maps data layers.  <\/p>\n\n\n\n

2.  Fixed a screen updating problem when zooming the Design \nWindow with a WMS layer displayed.<\/p>\n\n\n\n

Version 16.2.0 Enhancements and \nFixes<\/p>\n\n\n\n

1. Added a feature to the anchor picker dialog box.  Previously, \nif you were filling a polygon with receivers, you could select existing \nexclusions or existing sources as an anchor point.  You can now also use \nexisting receivers as an anchor point.  This is useful if you are laying out \nreceivers in multiple passes to create a project with variable point densities \nand need to line up receiver lines\/points with previously created lines.  This \nfeature also works for source lines.  <\/p>\n\n\n\n

2. Added a new source\/receiver editing mode that operates on \npoints inside a selected exclusion zone.  The primary goal was to provide an \neasy way to delete points inside an exclusion zone, however, there are \nadditional modes for turning points on\/off, snapping points to a grid, modifying \ninstrument settings, and removing the template assignments of points inside an \nexclusion zone.  <\/p>\n\n\n\n

3. The grid-based renumbering tool has been overhauled.  There is \nnow a cartoon display that shows the orientation and numbering pattern that will \nresult from the current parameters.  There is also a function for resorting and \nreordering the lines after performing the renumbering of the points.  This is \nuseful for surveys which have been created in multiple passes (or file imports) \nand you need to stitch lines together.  The previous function for reordering \nlines is still available in the View\/Reorder Lines tool. <\/p>\n\n\n\n

4. There is an export tool for P1\/11 files (Version 1.1).  This \ntools allows the editing of individual header records and the export of \nsource\/receiver position records and relational records.  Source and receiver \nattributes can be added to the source and receiver position records.  Blocks of \nheader definitions can be saved and re-used.  <\/p>\n\n\n\n

5. Updated the exclusion fill layout tools so that you can fill \nmultiple exclusions with source\/receiver lines and simultaneously not fill other \nexclusion zones.  This is useful if you are creating a project with variable \npoint densities in different regions.  <\/p>\n\n\n\n

6. In Edit Templates mode, there are now options for viewing all \nof the active receivers for a selected source and for viewing all of the sources \nthat fire into a selected receiver.  <\/p>\n\n\n\n

7. Added an option to the source editing toolbar for removing the \nmarine source flag from a towed streamer source.  This works in point, line and \ngroup modes.  There can be situations where marine source points get created or \nimported from P1\/90 files but the user actually wants to use the source \nlocations for fixed receiver shooting instead of for towed streamer shooting.  \nThis allows the user to “convert” the marine source points into sources that can \nshoot into OBS receiver geometries. <\/p>\n\n\n\n

8. Elevation GeoTIFF files can be converted into Slope GeoTIFF \nfiles.  <\/p>\n\n\n\n

9. Elevation GeoTIFF files can be exported as slope data in ASCII \nformat.  <\/p>\n\n\n\n

10. Added a feature to create the “line \nposition” for sources created with dual, triple, or greater shooting \nconfigurations.  In addition to the actual source location, an alternative \ncoordinate (named “line position”) which represents the source projected onto \nthe sail line can also be stored.  This feature has been added to Lines\/Bricks, \nZig-Zag, and Marine Sail Line creation.  For some calculations, such as fold \ncalculation, the actual source location may be desired,  For other calculations, \nsuch as line length, the line position coordinate may be more useful.  Use the \nAlternative Coordinates Window to swap in\/out the set of coordinates you wish to \nuse for a given program function.  <\/p>\n\n\n\n

11. Marine sail polygon-type exclusions can now be used as fill \nboundaries for the land layout tools (lines\/bricks, zig-zags, etc.) <\/p>\n\n\n\n

12. Added an option to create run-in shots in the sail line \ngeneration dialog box.  <\/p>\n\n\n\n

13. Added an option to the P1\/90 offshore export interface for \nexporting source points not flagged as towed streamer source points.  This is \nuseful if you want to export the source locations for an OBS geometry in P1\/90 \nformat.  Note–the locations of the nodes are not exported, only the source \nlocations.  <\/p>\n\n\n\n

14. Added fractal interpolation and kriging options when \nimporting an ASCII file for generating a data raster file (GeoTIFF).  <\/p>\n\n\n\n

15. Expanded KMZ output options to export the currently displayed \nbin attribute diagram and added many new options for parameterizing the color \nscale.  <\/p>\n\n\n\n

16. Added an option to export the currently displayed source and \nreceiver attributes to a KMZ file.  <\/p>\n\n\n\n

17. Added an option to select multiple marine sail polylines when \ngenerating marine shot points.  Previously, the choice was to sail one line or \nall lines.<\/p>\n\n\n\n

18. Added an option create marine sail \npolylines from existing source points.  One common use case is if the flip-flop \nparameters were used to create the source positions for an ocean bottom survey \nbut you then later wanted to have marine sail polylines to represent the path of \nthe vessel.  Another case is if you imported the source positions from an \nexternal file and need a way to generate the marine sail polylines.<\/p>\n\n\n\n

19. New options have been add to the exclusion zone resizing \ntool.  There are now three options for changing the shape of the expanded \npolygon to have squared, mitered, or rounded edges.<\/p>\n\n\n\n

20. Improved the speed of loading data into the Alternative \nCoordinates Windows.  <\/p>\n\n\n\n

21. Improved the speed of unshooting very large surveys.  <\/p>\n\n\n\n

22. Improved the layout speed when using the polygon fill option \nin Lines\/Bricks, ZigZag, Button and Radial layout options.  <\/p>\n\n\n\n

23. Fixed a drawing issue when using the option to draw \nconnecting lines between receivers or sources.  <\/p>\n\n\n\n

24. Fixed an issue creating CSV output from the Alternative \nCoordinates window.  <\/p>\n\n\n\n

25. Fixed an issue with not being able to perform undo\/redo \nfunctions after doing a resort of lines based on point numbers.  <\/p>\n\n\n\n

26. Improved the speed of entering Edit Templates mode on large \nsurveys.  <\/p>\n\n\n\n

27. Fixed an issue with the line name prefix and suffix not \ngetting updated during grid-based renumbering.  <\/p>\n\n\n\n

28. Several temporary files were being inadvertently left in the \ndata directory after closing MESA.  <\/p>\n\n\n\n

29. Fixed an issue with the visibility state of individual \nexclusion layers getting out of sync.   <\/p>\n\n\n\n

30. Fixed an intermittent crash when laying out marine sources \nalong existing sail polylines.  <\/p>\n\n\n\n

31. Fixed a crash in the marine sail lines dialog box.  If a user \naccessed this dialog box, closed it, and then created new marine polygons or \nmarine sail lines, this dialog box could crash upon re-opening.  <\/p>\n\n\n\n

32. Fixed a bug trying to graphically rotate exclusion zones.  \n<\/p>\n\n\n\n

33. Fixed a problem opening MESA databases created prior to \nversion 14.1.  These databases could crash v16.x depending on the selected map \nprojection.   <\/p>\n\n\n\n

34. Operation names in the Export to Marlin interface are now \nsorted alphabetically.  <\/p>\n\n\n\n

35. User settings in the Export to Marlin interface are now \npersistent and saved with the user settings.  <\/p>\n\n\n\n

36. Additional swath export options were added to the Export to \nMarlin interface.<\/p>\n\n\n\n

37. P1\/90 offshore import will import source \npositions from the file without or without cables defined.  <\/p>\n\n\n\n

38. Fixed an issue with the attribute crossplot \nnot displaying if receiver index or line index were being used for the x and y \naxes.  <\/p>\n\n\n\n

39. Fixed an issue with alternative coordinates \ngetting orphaned if a new set of marine source points was created as a \nreplacement for existing marine source points.  <\/p>\n\n\n\n

40, Fixed an issue with improper drawing of direct P and direct S \nraypaths in the 3D window.  <\/p>\n\n\n\n

41. Fixed an issue loading TIFF files that have extra samples per \npixel.  <\/p>\n\n\n\n

42. Fixed a drawing issue with illumination rays leaving the \nmodel space in the 3D window.<\/p>\n\n\n\n

43. Improved the speed of loading marine statistics.  <\/p>\n\n\n\n

44. Improved the speed of compacting marine streamer data files \nwhen saving a project.<\/p>\n\n\n\n

45. Fixed an issue with datum transformations not being stored \nproperly.  This is one of the database changes that is not backward compatible.  \nAfter saving a project using v16.2, you should not re-open the project with \nearlier versions of MESA.<\/p>\n\n\n\n

46. The Unit Template window can now be launched from the main \ntoolbar in the Design Window or by right-clicking on Shooting Configurations in \nthe Project Tree and selecting Open Unit Template Window from the popup menu.  \nThese changes were made to make access to the tool more apparent.  The Unit \nTemplate Window can still also be accessed from the Edit menu.<\/p>\n\n\n\n

47. Fixed an issue reading in the last well curve in a well \nset.<\/p>\n\n\n\n

48. Removed an erroneous “END” card that was getting written to \nthe last line of the XYZ export data file for model horizons.<\/p>\n\n\n\n

49. MESA now exports towed streamer and hybrid towed streamer + \nnode geometries to SimSurvey.  <\/p>\n\n\n\n

50. Fixed an issue reading in Gator MFA files in which line \nlength exceeded 4096 characters.<\/p>\n\n\n\n

Version 16.1.6 Enhancements and \nFixes<\/p>\n\n\n\n

1. Made a fix to WMS requests to preserve all parameters, such as \nauthentication keys.  <\/p>\n\n\n\n

Version 16.1.5 Enhancements and \nFixes<\/p>\n\n\n\n

1. Fixed an issue with plots resetting min\/max values for color \nscale ranges.<\/p>\n\n\n\n

2. Added a skew option for rectangular shooting that facilitates \n“H” style shooting.<\/p>\n\n\n\n

3. Fixed a bug with exporting line names from MESA to \nSimSurvey.<\/p>\n\n\n\n

4. Fixed a bug with alternative coordinate importing when the \nreceiver lines in the project are not ordered sequentially.<\/p>\n\n\n\n

5. There are new tools for renaming source\/receiver attributes \nand merging multiple attributes into a new attribute.<\/p>\n\n\n\n

Version 16.1.4 Enhancements and \nFixes<\/p>\n\n\n\n

1. Fixed an issue with hardcopy printing of ShapeFiles that \ncontain elevation data.<\/p>\n\n\n\n

2. Modified line\/station data that gets exported to \nSimSurvey.<\/p>\n\n\n\n

3. Fixed an issue with the color scale defaulting improperly when \nexporting fold displays to KMZ.<\/p>\n\n\n\n

Version 16.1.3 Enhancements and \nFixes<\/p>\n\n\n\n

1. Unused templates are no longer exported to Marlin or \nSimSurvey.<\/p>\n\n\n\n

2. Fixed an issue related to Blue Marble licensing<\/p>\n\n\n\n

3. Changed the SPS header card containing the datum transform to \nuse units of arc seconds.<\/p>\n\n\n\n

Version 16.1.2 Enhancements and \nFixes<\/p>\n\n\n\n

1. Added vessel and airgun IDs from P1\/90 import to MESA marine \nshot points.<\/p>\n\n\n\n

Version 16.1.1 Enhancements and \nFixes<\/p>\n\n\n\n

1. Fixed a checkbox bug in the interface for transferring a MESA \ngeometry to SimSurvey.<\/p>\n\n\n\n

2. Fixed an issue in which the flip flop layout was incorrectly \nculling out points that fell outside of a boundary polygon.<\/p>\n\n\n\n

3. Fixed an issue with polygon fill layout methods leaving an \nunwanted gap in the certain lines.<\/p>\n\n\n\n

4. Fixed a crash in the GeoTIFF resampling routine.<\/p>\n\n\n\n

5. Fixed an issue exporting geometries to NORSAR when the project \nhas multiple marine configurations.<\/p>\n\n\n\n

6. If a MESA towed streamer geometry contains a feather angle, \nthe geometry will be converted into a geometry with individual hydrophone \npositions when exported to NORSAR.<\/p>\n\n\n\n

7. Fixed a performance issue decimating the vertices on a large \ngroup of sail polylines.<\/p>\n\n\n\n

Version 16.1 Enhancements and Fixes<\/p>\n\n\n\n

1. Added a decimated layout tool to the Lines\/Bricks layout.  \nThis new option applies a “jitter” to the line layout in which gaps are randomly \ninserted into the lines in the inline direction.  The gaps are constrained so \nthat the maximum inline gap size is controlled, as well as the number of \nconsecutive maximum size gaps.  There is also a crossline constraint so that the \nnumber of gaps in the crossline direction can be controlled. <\/p>\n\n\n\n

2. A decimation function has been added to the Utilities menu.  \nThis tool has four modes for removing sources and\/or receivers from the \nproject.  The first mode will randomly remove a percentage of points.  The \nsecond mode will randomly remove a fixed number of points from the project.  The \nthird mode will randomly keep a fixed number of points in the project.  The \nfourth mode will remove every nth point along each line.<\/p>\n\n\n\n

3. The randomization utility has been updated from a simple \nrandomization in the x and\/or y direction.  There are now options for \nrandomizing source and receiver positions based on the inline\/crossline bearings \nof a bin grid, the receiver design grid, or the source design grid.  In \naddition, the randomization function will optionally snap points to grid lines.  \nAs part of this feature update, MESA is now using a higher quality randomization \nfunction than in previous releases.<\/p>\n\n\n\n

4. MESA 16.1 allows access to streaming satellite imagery, \ntopographic maps, and hillshade imagery provided by Airbus.  In order to access \nthe imagery from Airbus, the MESA license must be on active maintenance.  If \nyour MESA license is not currently active on maintenance, you can still access \nWMS data through your own link to a different server. <\/p>\n\n\n\n

5. An anchor point selection tool has been added to the layout \ndialog boxes.  The anchor point tool allows you to fine tune the location of \nsource and receiver lines when filling regions.  This tool will allow you select \na vertex from an exclusion zone to use as a positioning anchor point or you can \nselect an existing receiver(source) location as a positioning anchor.<\/p>\n\n\n\n

6. Fixed a problem with Unicode characters in the name of the \nproject path. <\/p>\n\n\n\n

7. Fixed an issue with slow import of P190 files.<\/p>\n\n\n\n

8. Fixed a display issue with the color of certain TIFF files. \n<\/p>\n\n\n\n

9. Fixed a TIFF import issue with files downloaded from the USGS \nTopoView website. <\/p>\n\n\n\n

10. Fixed an issue with the flip-flop source separation parameter \nnot honoring decimal points in the Lines\/Bricks Layout dialogs. <\/p>\n\n\n\n

11. Fixed an issue with exporting Pattern files (.ptn) using \nsmall surveys.<\/p>\n\n\n\n

12. Fixed an issue with MESA crashing when performing an undo of \nsource attribute assignment in line and group modes.  <\/p>\n\n\n\n

13. Fixed an issue in which the loaded map projection was lost if \na user canceled out of opening a new project. <\/p>\n\n\n\n

14. Fixed an issue with writing MESA projects to network drives.  \n<\/p>\n\n\n\n

15. Fixed a problem with negative velocity gradients in Model \nBuilder. <\/p>\n\n\n\n

16. Fixed a display problem in the Incidence Angle Window.  \nAmplitudes and travel times are now properly colored according to the color \nscales.  <\/p>\n\n\n\n

17. Fixed a problem changing the color scale when displaying the \nresults of illumination raytracing.  <\/p>\n\n\n\n

18. Fixed differences between the Expert CRP fold display and the \nCRP fold calculation display that resulted from significant figure differences \nbetween the bin grid origins for the two calculations.  <\/p>\n\n\n\n

19. Model-based Expert attributes were previously based on the \nmaximum horizon dip and the horizon dips in the x and y directions.  The maximum \nhorizon dip option is still available, however the x and y dip attributes have \nbeen replaced by an apparent dip option and the user can now calculate model \nattributes along any bearing.  <\/p>\n\n\n\n

20. Fixed an issue with stretch mutes not being properly applied \nto CRP attribute calculations from raytracing results. <\/p>\n\n\n\n

21. Removed an unnecessary time stamp element in KMZ output that \nadded a time slider to Google Earth displays.  <\/p>\n\n\n\n

22. Fixed a crash when accessing the shooting detail for a salvo \nshooting configuration. <\/p>\n\n\n\n

23. Fixed a drawing issue with range\/bearing symbols.<\/p>\n\n\n\n

24. Changed WMS image drawing to work on a background thread for \nbetter performance. <\/p>\n\n\n\n

25. Fixed an issue creating exclusion zones from DXF or VYR \nfiles. <\/p>\n\n\n\n

26. Fixed an issue with certain single station edit modes that \ncould lead to crashes.  <\/p>\n\n\n\n

27. Fixed an issue outputting marine sail polylines to KMZ \nformat. <\/p>\n\n\n\n

28. Added an option to the MESA export to SimSurvey that will \nconsolidate duplicate source points into a single source location in the \nSimSurvey project.<\/p>\n\n\n\n

29. Fixed an issue with the Marlin and SimSurvey export functions \nso that they work with sorted and unsorted source record numbers. <\/p>\n\n\n\n

30. Fixed a bug selecting duplicate source locations when \nnon-duplicate sources are filtered off. <\/p>\n\n\n\n

31. Fixed a bug with the total traces count in the Bin Statistics \nwindow.  The count was incorrect for surveys with 4B+ traces. <\/p>\n\n\n\n

32. Fixed a bug exporting template information from the Edit \nTemplate toolbar. <\/p>\n\n\n\n

33. Modified the default data directory for Gator attributes to \nbe the default data directory instead of the current working directory. <\/p>\n\n\n\n

34. Screenshot settings are now getting saved to the user \npreferences. <\/p>\n\n\n\n

35. Fixed a crash during map projection translation when \nreceivers lines have different lengths. <\/p>\n\n\n\n

36. Fixed a crash when saving projects using ED50 map \nprojection.  This was due to datum transformations that can not be properly \nconverted to WKT.  <\/p>\n\n\n\n

37. Fixed a problem with the NORSAR geometry export not \ntransferring feathered streamer locations.  <\/p>\n\n\n\n

38. Improved the polygon fill logic for including points that \nfall directly on rotated boundaries. <\/p>\n\n\n\n

Version 16.0 Enhancements and Fixes<\/p>\n\n\n\n

1. A feature was added to create polygonal exclusion zones based \non slopes derived from GeoTIFF files containing elevation data.  Users can \nspecify a slope threshold in either degrees or percentage.  Each data point in \nthe file is analyzed from multiple azimuths to calculate the maximum slope at \nthat location. <\/p>\n\n\n\n

2. There is a new shooting mode for adding \nfixed receivers to a towed streamer geometry.  If you have a marine towed \nstreamer design and wish to have the sources also fire into either ocean bottom \nnodes or cables, this feature will allow you to create merged shooting \ntemplates.  You can also import P190 files with a towed streamer geometry and \nadd nodes or bottom cables to the template. <\/p>\n\n\n\n

3. Three new colorscale files were added to the installation.  \nThese files are named cividis.csi, viridis.csi, and inferno.csi.  These \ncolorscales were added for two reasons:  Helping users with red-green color \nblindness and providing an alternative to the default rainbow colorscale.  \nRecent research has shown that colorscales which increase linearly both in hue \nand brightness are easier to interpret for those with red-green color \nblindness.  Additionally, the same research has suggested that rainbow \ncolorscales can lead to incorrect interpretation of data by artificially \ninserting hard color changes into maps.  The same linear increase in hue and \nbrightness that helps those with color blindness can actually improve the \nperception of those without color blindness as well.  The new colorscales have \nthe following color schemes:<\/p>\n\n\n\n

cividis.csi – Navy blue on the low end increasing to bright \nyellow on the high end<\/p>\n\n\n\n

viridis.csi –  Deep indigo on the low end, teal in the middle \nrange and bright yellow on the high end<\/p>\n\n\n\n

inferno.csi – Black on the low end, red-orange in the middle \nrange and bright yellow on the high end<\/p>\n\n\n\n

By default, these colorscales will be installed in \nC:\\ProgramData\\GreenMountain\\colorscales.  However, if you have an existing MESA \ninstallation, you will have User Preferences set to a different colorscale \ndirectory.  The installation program overrides the User Preferences the first \ntime MESA 16.0 is launched.  In order to use your previous colorscales, you will \nhave to update your User Preferences to point to \nC:\\ProgramData\\GreenMountain\\colorscales15 (or \\colorscales14). <\/p>\n\n\n\n

4. The label shooting interface has been greatly enhanced to \nhandle more types of geometries.  Instead of an inline and a crossline roll \ninstruction, there are now two roll instructions which are independent of line \ndirection.  This allows users to shoot a variety of geometries in which source \nlines can be parallel or perpendicular to the receiver lines.  The roll preview \nfunctions have been improved and a function was added to change the location of \nthe starting patch. <\/p>\n\n\n\n

5. A tool was added for analyzing 4D attributes.  This tool \nallows users to compare the bin attributes from two surveys, match traces in \nspecific offset ranges, and display a variety of standard 4D attributes \n(delta-source, delta-rec, delta-source+delta-rec, delta azimuth, and the inline \nand crossline components).  These attributes can also be analyzed in the \nhistogram window.  In addition, the Alternative Coordinates window was upgraded \nto calculate inline and crossline offset differences so that 4D attributes can \nbe analyzed from geometry differences alone instead of matching traces in the \nbin attributes. <\/p>\n\n\n\n

6. A tool was added for creating marine detours around \nplatforms.  This tool is on the exclusion editing toolbar and can be used to \ncreate either close pass detours or to terminate sail polylines as dead heads.  \n<\/p>\n\n\n\n

7. An interface for exporting MESA projects to MESA’s SimSurvey \ntime and motion analysis module was added.  This allows users to create an ocean \nbottom geometry in MESA and run scenarios in SimSurvey to calculate the most \ncost efficient and time efficient deployment scenarios. <\/p>\n\n\n\n

8. An interface for exporting MESA projects to ION’s Marlin \nsimultaneous operations management module was added.  This allows users to \ncreate a marine\/OBS geometry in MESA and initialize the simultaneous operations \ntracking in Marlin. <\/p>\n\n\n\n

9. A new type of offset histogram was added to the bin attribute \noffset diagrams.  Offset bars can now be colored according to azimuth from 0 to \n360 degrees.  <\/p>\n\n\n\n

10. Added an option for creating triple source flip-flop \ngeometries to the line\/brick layout options for sources and receivers.  <\/p>\n\n\n\n

11. Added an option for creating flip-flop and triple source \npatterns to the circular source layout in the Unit Template Window.  <\/p>\n\n\n\n

12. An xy-shift option was added to the translation\/rotation \nutility. <\/p>\n\n\n\n

13. Added a selection mode to the bin contribution tool that \nallows the user to select all bins which fall inside of an exclusion zone. <\/p>\n\n\n\n

14. A feature was added that will normalize NORSAR hitmap \nattributes to use the same CMP bin grid size as used in MESA.  <\/p>\n\n\n\n

15. The NORSAR interface has been enhanced.  In version 15.2, \nNORSAR grid-based raytracing attributes could be imported into MESA for \nanalysis. In version 16.0, there is a new format of NORSAR attributes that can \nbe imported–point attributes.  These attributes are imported as source and\/or \nreceiver attributes.  This type of attribute can be displayed in map views, in \nhistograms, in attribute crossplots, and in pie charts.  These attributes can \nalso be used in filtering operations, which makes it easy remove sources and \nreceivers which are not contributing to the illumination of a target.  <\/p>\n\n\n\n

16. Added a feature to change units from ft->m or m->ft \nduring the rectification of GeoTIFF files. <\/p>\n\n\n\n

17. Added an option to change the line thickness of polylines or \npolygons loaded from Shapefiles.  <\/p>\n\n\n\n

18. The translation\/rotation utility is now available for towed \nstreamer marine projects. <\/p>\n\n\n\n

19. There is a new export option in the Shapefile Output for \nwriting the active bin grid to a Shapefile.  <\/p>\n\n\n\n

20. The option for exporting source\/receiver polylines in the \nShapefile Output will now write out the source\/receiver line name as the label \nvalue in the exported Shapefile.  <\/p>\n\n\n\n

21. A feature was added to decimate vertices in an exclusion \nzone.  This can be necessary when you have created exclusion \nzones by importing external data or created exclusion zones by calculating \nslopes from elevation data and have numerous colinear or near-colinear points.  \nIf exclusion zones are unnecessarily oversampled, it can severely affect the \nperformance of exclusion-related functions–especially for surveys with a large \nnumber of sources\/receivers.  <\/p>\n\n\n\n

22. Added P10 and P90 percentile calculations \nto the Histogram Window. <\/p>\n\n\n\n

23. Fixed a colorscale problem with bin attribute diagrams in the \n3D window <\/p>\n\n\n\n

24. Fixed an issue with the default screenshot directory not \nbeing set properly prior to saving a project for the first time.<\/p>\n\n\n\n

25. On startup, MESA now checks for a valid, writeable \nGMG_DATA_DIRECTORY data folder.  If MESA doesn’t find a folder the user is now \npresented with an option to select a directory or quit. <\/p>\n\n\n\n

26. Fixed an issue with editing and applying changes to floating \npoint logarithmic color scales.<\/p>\n\n\n\n

27. Added a file header check so that incorrectly formatted JPEG \nfiles won’t cause MESA to crash.<\/p>\n\n\n\n

28. Fixed an issue with the exclusion repel function not working \nproperly after multiple undo\/redo events.<\/p>\n\n\n\n

29. Improved the performance of the group move function on \nprojects with large numbers of sources\/receivers.<\/p>\n\n\n\n

30. Fixed an issue in line editing mode in which points were \nsnapping to the wrong grid line.<\/p>\n\n\n\n

31. Fixed a display issue in the bin statistics report in which \naverage fold values were getting clipped. <\/p>\n\n\n\n

32. Fixed an issue with filtering on instrument types not working \nproperly.  <\/p>\n\n\n\n

33. Fixed an issue with fold calculations.  If a project had more \nthan 2.1 billion traces and the user’s computer had more than ~60GB of RAM, fold \ncalculations would crash or produce an empty file. <\/p>\n\n\n\n

34. Fixed an issue with temporary bin and midpoint files not \ngetting removed properly. <\/p>\n\n\n\n

35. Fixed an issue with the shot point consolidation routine \nskipping certain source points.  <\/p>\n\n\n\n

36. Improved the speed of bin grid generation for large marine \nsurveys.  <\/p>\n\n\n\n

37. Fixed an issue where filling a polygon with marine sail lines \nwould sometime result with an occasional source line dropping the last source \npoint on the line. <\/p>\n\n\n\n

38. Added a check to the Smart Aperture tool so that the maximum \nincidence angle is equally divisible by the polar angle interval.  <\/p>\n\n\n\n

39. Improved the performance of large copy and \npaste operations in the source and receiver spreadsheets. <\/p>\n\n\n\n

40. Added the number of live sources to the \nheader records of the MESA ASCII Pattern output file.  <\/p>\n\n\n\n

41. Added an option to the Gator attribute \nimport function.  Users can now use either the “Line Name” or “Preplot Name” \nfields in Gator attribute files to match line names in the MESA project.  \n<\/p>\n\n\n\n

42. Fixed a problem with towed streamer \ngeometries with streamer depths not producing rays for certain models during \nraytracing.  <\/p>\n\n\n\n

43. Fixed an issue changing the line name in \nthe spreadsheets if the line name started with the same digit as the point \nindex. <\/p>\n\n\n\n

44. The free WMS imagery available through \nDigital Globe’s Spatial on Demand 5.0 is no longer available as of Jan 1, 2019.  \n<\/p>\n\n\n\n

45. Fixed an issue with the drawing of \ndynamically sized labels for Shapefiles.  <\/p>\n\n\n\n

46. Fixed an issue with selecting Save As from \nthe Project Tree behaving differently from selecting Save As from the File menu. \n<\/p>\n\n\n\n

47. Custom WMS addresses can now be saved to \nthe global defaults xml file and re-opened in new projects. <\/p>\n\n\n\n

48.  Upgraded to Blue Marble version 7.4 map \nprojection libraries.  Included in this upgrade is the ability to access the \nBlue Marble projection editing interface for creating\/modifying custom map \nprojections. <\/p>\n\n\n\n

49. Fixed an issue with integer numbers being \nincorrectly parsed by the LAS well log import tool. <\/p>\n\n\n\n

50. Fixed an issue in which the last segment of \nthe well trajectory was not appearing in the Design Window. <\/p>\n\n\n\n

51. Fixed an issue in which vertical stations \nwere being placed at elevation intervals instead of using distance along the \nborehole.  <\/p>\n\n\n\n

52. Fixed an intermittent crash that occurred \nwhile importing string attributes. <\/p>\n\n\n\n

53. Fixed an issue with defining source \ninstrument types.  When called from certain layout tools, the interface for \ndefining receiver instruments was opening instead of the interface for defining \nsource instruments.  <\/p>\n\n\n\n

54. Fixed an issue importing source depth from \nSPS files.  <\/p>\n\n\n\n

55. Fixed an issue with the SPS update \nfunction.  The “attribute to set on import” option was not properly updating \nstring attributes.  <\/p>\n\n\n\n

56. Fixed an issue reading line numbers in the \nGator attribute import function.   <\/p>\n\n\n\n

57. A control was added to the Gator attribute \nimport function that hides the quality attributes from the list of available \nattributes.  <\/p>\n\n\n\n

58. A control was added to the Gator attribute \nimport function to specify the number of digits in the station number.  \n<\/p>\n\n\n\n

59. If the number of marine source points is \nmodified in a project that has previously been saved, a new prompt will appear \nwhen saving the project.  This prompt will ask if you wish to run a compaction \nprocedure on the file that stores the marine receiver locations.  Previously, \nthis compaction procedure was performed automatically to save disk space.  \nHowever, the procedure can take a long time so now the user is prompted whether \nto perform the compaction or to skip the procedure.  <\/p>\n\n\n\n

60. Fixed an issue in the ASCII import window \nin which the window kept scrolling back to the first line of the file.  It will \nnow stayed fixed on the defined first data line in the file.  <\/p>\n","protected":false},"excerpt":{"rendered":"
