Greatly sped up rendering of some layers when reprojected, particularly online sources that use Web Mercator when displayed in Geographic or Mercator/WGS84
Fixed Security Vulnerability in NCSECW.dll (CVE-2010-3599)
Fixed OpenSSL Heartbleed vulnerability. This only affected the PostgreSQL support
Updated XTF (eXtended Triton Format) import to create mosaic from sidescan sonar data
Added support for additional HDF5 elevation grid data formats
Added support for loading AVS UCD format with 3D TIN features
Added support transforming the coordinates of Lidar point clouds, including graphically rectifying them, providing a transform (shift, rotate, and scale), and doing a file-based coordinate-to-coordinate transformation, including via .gm_xform file.

Fixed bug with creating of grid using binned grid methods to Feet elevation units creating a grid that says meters when the values are in fact feet

New in Global Mapper SDK 15.1 (Feb 5, 2015)

SDK Function Updates:
Added GM_SaveWorkspaceEx so you can save a workspace file with a custom layer ordering or subset of layers.
Added GM_RemoveCustomBrushStyle function to allow removing a previously added custom brush style.
Allow cancel of draws using the GM_DrawFlags_IncrementalRender flag. Return FALSE from the progress callback when GM_PROGRESS_RENDER_UPDATE is provided.
Updated GM_FindFeaturesInArea to also find partially overlapped lines and areas if you pass in a GM_FindFlags_PartialOk flag.
Major Improvements also in GM15.1:
Added support for loading data from and exporting data to MS SQL Server Spatial databases.
Updated the Raster Calculator to support calculations from elevation grid layers. You can now apply any custom formula to loaded terrain layers to create a new terrain layer. The layer may actually be a grid of other non-elevation values, like NDVI values, etc., so this opens up an entirely new set of analysis possibilities.
Dramatically sped up raster/elevation exports cropped to complex area features. For very complex areas (i.e. hundreds or thousands of vertices) the exports may be 10x as fast or even better!
Added built-in links several online sources, including all NASA GIBS (Global Imagery Browse) sources, Landsat8 imagery and Lidar data from the USGS EarthExplorer web site, and GlobCover ESA2009 Land Cover data.
Added new Recent File Types filter in the GM_SelectFiles dialog to track commonly used file types. As you open files those you use the most often will be added to that filter. It will start with the contents of the Commonly Used Formats filter, but will adapt over time as you use the software.
Added support for loading generic MS Access (MDB) files with point data. Users are prompted for the fields to pull coordinate data from. This works for things like GPSeismic files. Note that because there is not a 64-bit MS Access driver generally available you have to use the 32-bit Global Mapper SDK to load these files.
Added support for loading Leica PTS point cloud, ECRG toc.xml, ECW v3, Trimble Field Survey XML, Kongsberg SIS plan format, and Finnish Land Siurvey GML files.

New in Global Mapper SDK 15.0 (Feb 5, 2015)

Significant New Features:
New raster calculator features mathematical operations for work with multi-band imagery for extracting and leveraging a variety of information from the imagery using pre-defined formulas, like NDVI and NDWI, or custom free-hand formulas
New binning methods for gridding LiDAR point clouds. Create a regular grid from the minimum, maximum, or average value in individual "buckets". This method is extremely fast compared to the normal triangulation-based approach
Ability to edit and re-calculate multiple view shed layers
Faster drawing of reprojected and large LiDAR point clouds by using multiple cores/processors
Added GM_GetLayerLidarStats function to get LiDAR statistics from a point cloud layer
Added support for saving LiDAR statistics from a script
Scripting enhancements such as passing variables to the script from the command line
Updated ECW/JPEG2000 read support to use new ECW SDK v5.0 from Intergraph
Added support for drawing points from a point cloud as a 'height above ground'. This will determine a ground elevation for all locations under the point cloud (using classified ground and water points if available) and then display the height relative to that
Added support for new ASPRS classifications 40-45 from Topo-Bathy Profile for bathymetric points
New Supported Formats:
Added support for importing and exporting 3D PDF files. Underlying data format in PDF 3D Annotations may be U3D or PRC. However PRC is not supported at this time
Added support for loading E57 LiDAR files
Added support for CMIP5 HDF5 data sets with sea surface temperatures
Added support for loading text files with the coordinates stored as ECEF (Earth-Centered Earth-Fixed) coordinates. The Coordinate Format drop-down on the ASCII Text Import dialog has an option to specify that the coordinates are ECEF
Added support for GCP (control-point) files with the pixel coordinates specified as a percentage value rather than an absolute pixel coordinate. Useful when users have text placement files with just the corner coordinates users can easily add 0% or 100% for the X and Y pixel coordinates of each corner to get a good placement

New in Global Mapper SDK 14.2 (Feb 5, 2015)

New in Global Mapper SDK 14.1 (Feb 5, 2015)

New in Global Mapper SDK 14.0 (Nov 16, 2012)

Added GM_GetFeatureElevation function for retrieving the elevation of a single feature.
Added GM_ProjectPointFromECEF and GM_ProjectPointToECEF functions for ECE (earth-centered earth-fixed) coordinate support.
Added support for exporting BIP and BSQ format files using GM_ExportRaster(Ex).
Added GM_MiscOpt_PositionDisplayFormat option for setting the position display/export format used for things like Simple ASCII text export.
Updated MrSID libraries to use lti_dsdk_8.5.dll as filename to avoid potential collisions with other applications/libraries using different versions of the LizardTech MrSID libraries.
Added support for spatial databases (see list below) for both import and export (currently only via workspace load using GM_LoadLayerList function).
Added support for adding WFS (Web Feature Services) online data sources for dynamically loading online vector data sources.
Added support for adding WMTS (tiled WMS) online data sources.

Added support for elevation GeoTIFF files with 64-bit double-precision samples.
Added support for numeric and character looping in scripts using new VAR_LOOP_START and VAR_LOOP_END commands. This allows you to step through some range of numbers or characters in a script, including simple loop counters or numbers like coordinates.
Added support for looping over loaded layers in scripts using new LAYER_LOOP_START and LAYER_LOOP_END commands. This allows you to step through any loaded layers to perform operations based on some current layer.
Added new CALC_ATTR script command to allow calculating new or updating existing attribute values in a script, including numeric calculations between an attribute an another attribute or a fixed value and appending or prepending text to existing attributes.
Added new EDIT_MAP_CATALOG script command to allow creating new map catalogs and adding and removing maps from existing map catalogs from inside a script.
Added new SET_LAYER_OPTIONS script command to allow setting the display options of a loaded layer without having to unload the layer and re-import it.
Allow use of the SHAPE_TYPE parameter to filter which types of objects (i.e. areas, lines, and/or points) are considered for the EXPORT_VECTOR and EDIT_VECTOR commands.
Added support for TRANSFORM_FILENAME parameter for IMPORT command in script to provide a coordinate-to-coordinate (rather than pixel-to-coordinate like the GCP_FILENAME parameter) when loading a layer.
Added support for specifying the SPATIAL_RES parameter for export commands as percent values rather than raw numbers, to easily allow adjusting native resolutions.
Fixed issue with folders being created for each possible output when gridding even if no files end up being created there.
Added option to mark duplicate features with a DUPLICATE=Y attribute by adding MARK_DUPLICATES=YES to the EDIT_VECTOR command rather than just marking them as deleted. You can specify IGNORE_ATTRS=YES to only match on geometry and not also attributes, but now specify DUPLICATE_ATTR parameters to indicate some attributes that do need to be identical.
Allowed use of POLYGON_CROP_FOLDER_ATTR without also using POLYGON_CROP_NAME_ATTR to insert a folder into an output filename path.
Updated SET_LOG_FILE command to add a version string and timestamp to the log file.
Added new GRID_TYPE_PIXEL_SIZE_MAX parameter for EXPORT_RASTER and EXPORT_ELEVATION script commands to allow specifying that gridding should be done to a maximum pixel size, but then the actual pixel size shrank to get same-sized tiles that exactly cover the specified export bounds rather than making the last row and column of tiles possible go past the edge.
Added support for providing a coordinate offset and scale (COORD_OFFSET and COORD_SCALE parameters) when exporting Lidar LAS files with the EXPORT_VECTOR command.
Fixed issue with the EXPORT_RASTER command when running a script from a command prompt whereby if you only had vector data loaded it wouldn’t be found.
Fixed COMBINE_TERRAIN script command to by one pixel larger in size to better maintain the sample spacing.
Fixed JOIN_LAYER command to work with formats other than Shapefiles.
Added option (TIFF_NO_GTIFF_HEADER) to disable writing out a GeoTIFF header when exporting a TIFF file.
Add option to prepend a blank line to the start of empty files being appended to with the GENERATE_PATH_PROFILE script command by adding an ADD_BLANK_LINE=YES parameter.
Updated DIR_LOOP_START to allow specifying .. (two dots) as the FILENAME_MASK parameter for just looping over directories without needing to specify a file inside the folders.
Added new SRTM terrain source hosted on globalmapper.com that is more reliable and much faster than the previous source hosted on a NASA/JPL server. The old source is still available with the text ‘Backup Source’ at the beginning of the source name just in case the new source is ever not available for any reason.
Added support for merging WMS sources comprised of multiple layers into a single download if the WMS server supports it. This is useful for vector data available as different layers.
Added drop-down lists to explicitly select the projection and file format to use when creating new WMS/WMTS sources so that you don’t have to provide it as part of the service name anymore if you want something other than the default.
Added support for adding custom tile-based sources that use quadtree naming (like Bing Maps). You just specify a custom URL string and use %quad for the quadtree name placeholder rather than %x, %y, and %z.
Added option for custom WMS sources to draw using a single download per screen draw rather than using tiles. This is useful for sources that add watermarks to each download from the WMS server. This option is available by right-clicking on a WMS source in the source list.
Updated TMS web export to generate a tileset XML file rather than an HTML file.
Added option to skip existing tiles for WorldWind Export, allowing you to split a large export among multiple running instances of Global Mapper.
Added support for WMS sources that go from 0-360 rather than -180 to +180.
Added Norwegian Transverse Mercator (NTM) zoned projection as a built-in projection.
Added ED50 (Malta) and Sphere Radius 6378137 m as built in datums.
Renamed Quebec MTM projection to MTM (Eastern Canada) to reflect that the projection is used for more than just Quebec.
Updated Hotine Oblique Mercator/RSO projections that use Azimuth Point parameter to save to PRJ files as ‘Longitude_of_Center’ rather than ‘Central_Meridian’ so that Esri products will recognize it.
Use TOWGS84 parameters in a WKT PRJ file to select an appropriate datum specialization for datums like ED50 that have lots of transformation parameters available.
Updated New Israeli Datum transformation parameters based on official values from Israeli authorities.
Added support for using a default.prj file in the App Data folder (see Help->About dialog to set) in addition to the .exe file path.
Updated watershed calculation to make the streams 3D lines and ensure that the stream elevation always flow 100% downhill, even through depressions.
Updated watershed calculation to save an input flow attribute (IN_FLOW) for each stream and also renamed the MAX_FLOW attribute to OUT_FLOW.
Added new custom Half Pie and Half Pie (Empty) point symbols that allow for custom sizes and colors for the same shape of symbol.
Allow overwriting loaded Shapefiles with large DBF files. Previously you would get an error if trying to overwrite them if they were currently loaded due to the DBF file being held open.
Added option to specify a bounding box to load when loading Lidar point cloud data. Useful for limiting your load to just a small region for very large Lidar files.
Fixed rare incorrect coloring of some PDF files in the 64-bit version.
Greatly improved performance when exporting from online sources that occasionally return invalid image files.
Fixed problems drawing some symbols from IoGas .gas files.
Added support for GDAL “no data value” tag (42113) when reading and writing elevation GeoTIFF files.
Added option to generic ASCII text import to create areas from closed line features if no CLOSED attribute is specified for the feature.
Fixed error loading high bit depth NITF files with embedded JPEG2000 images in v13.2.
Sped up rendering of ECW, MrSID, and JPEG2000 images when zoomed out a bit on them. They are no longer automatically interpolated to improve appearance as it’s not needed for multi-level formats like those.
Limit field length and allowed characters in exported DBF files (such as with Shapefile export) to 254 characters as ESRI products can’t handle the full supported 255 character length and also can’t handle any special characters in DBF field names.
Fixed issues with some .ntf files being recognized as NTF Grid files rather than NITF files and not loading.
Corrected flight date written to Lidar LAS files to be days of year rather than days in month so it won’t always be in January.
Display FLIGHT_DATE for Lidar LAS files in the metadata for the layer.
Fixed issues in v13.2 that could cause some buffer areas to be created with spikes back to the original feature being buffered.
Updated SPS format load to auto-detect the format version if no header was provided so that the attributes can be decoded properly from SPS v2.x files.
Corrected cell type written to ERS files exported along with floating point BIL elevation files.
Improved handling of loading multiple unknown file types at once by remembering the type selected if prompted. Also made MSI Planet files load regardless of filename.
Made sea level display as blue in the Global Shader.
Added support for loading JP2 files with no embedded position information but with an accompanying .aux.xml file with position information.
Support additional GML flavors, like new OSGB INSPIRE maps.
Improved loading of LandXML files, including adding support for loading contour lines.
Added support for using index.txt (and other index files from MSI Planet) to position most image formats, like BMP.
Fixed issue from v13.2 loading NITF files with embedded high-bit-depth JPEG2000 images.
Significantly sped up the drawing speed of some NITF files with embedded JPEG2000 images.
When loading KML files, obey any designated and for custom icon symbols.

Load many geospatial PDF files at higher resolution.
Added built-in access to geologic map datasets for most of the world using the GM_LoadOnlineLayer function.
Added new build-in USA Topo Maps source (replacing the msrmaps.com USGS DRG source which is no longer
offered by Microsoft as of May 1, 2012).
Make WMS sources with a specified legend image (like some of the Geologic Maps just added) automatically
show that legend image as a separate layer.

Added support for initializing custom shaders from Hypack HCF files.
Add built-in support for TWD67 (Taiwan) and Wisconsin County (Marathon) datums.
Improved accuracy of OSGB36 datum transformation in offshore areas where the grid shift file is
inaccurate. In order to still provide a way to explicitly use the NTv2 grid shift or choose the
7-parameter transformations, the existing Ordnance Survey 1936 datum was renamed OSGB36 (Best Transform)
and 2 new specializations, OSGB36 (Grid Shift) and OSGB36 (7-Parameter) were added so that uses that need
a particular transformation can choose the one that they need.
Improved accuracy of nautical miles as units of measure. The conversion factor was inexact.
Made NAD27 datum specializations (like NAD27 Mexico) use the proper explicity datum code when exporting to
MapInfo files rather than the generic NAD27 datum code.
Allow providing a rotation angle for Polyconic projections.
Added support for automatically adding custom datum definitions from GeoTIFF files using the GeogTOWGS84GeoKey tag.
Improved accuracy of State Plane Alaska Zone 1 projection conversions.
Corrected display of Robinson projection with non-zero central meridian.
Added right-click option on feature vertices dialog to allow providing offset and scale factors for selected elevation values.
Fixed problems using some ECW files.
Added new option to GM_ContourParams_t to create the contour lines as the terrain passes to the contour height from above it rather than using the default of creating it when the terrain goes from the contour height to lower elevations.
Allow cropping to a selected area when exporting to MapInfo MIF/MID or TAB/MAP files.
Added support for reading KML attributes from tags.
Added support for reading and writing KML tags.
Fixed long-standing issues loading many types of JPEG2000 files, particularly large NAIP imagery files that used to lock up or render very slowly.
Corrected auto-assignment of Lidar point types for classes 10 and up, including adding a new Lidar Bridge and Road point types.
Made commas and semi-colons be the first checked for delimiters when doing an auto-detect of delimiter on import of generic ASCII text files.
Updated S-57 import so that if you have customized the style to use for Isobath areas that style is used rather than an auto-assigned solid shade of blue based on depth.
Updated 3D view options dialog to have OK, Apply, Cancel, and Help buttons rather than updating the view immediately as you are changing values. This prevents inadvertent changes and very slow editing of values with large data sets loaded.
Made Arc ASCII Grid exports write no-data value as -9999.0 rather than just -9999 so that ESRI products don’t treat the grid as an integer grid rather than a floating point grid.
Made text file/CSV import not replace \n text in filenames or URLs with a newline character.
Added support for loading UKOOA P/190 files that do not conform to the format specification.
Use font rotation and placement information from OSGB MasterMap GML files.
Fixed problem with custom OSM/TMS/Google Maps tile URLs with variables in them and also ampersand (&) characters not working due to the ampersands being converted to their escape sequence (&).
Fixed number of zoom levels used for custom OSM/TMS/Google Maps sources. The custom sources were only going to one less zoom level than specified (i.e. if you specified to go to zoom level 18 it would only go to 17). Note to get the correct zoom level behavior you would need to re-add your source.
Fixed issues drawing scaled semi-transparent custom symbols or printing them. The semi-transparent areas would not render properly.
Corrected MAX_FLOW and DRAIN_AREA calculations for streams in watershed calculation. They were showing values for anything flowing to the end point of a stream rather than just what could flow along that stream.
Made walk mode height stick on 3D view options dialog and also be remembered between runs.
Allow cancel of DTED file load.
Fixed searching on addresses with accent characters.
Fixed problem in v13.1 with some JPEG2000 files coming in with a Geographic projection but units of meters, so it can’t be reprojected.
Allowed larger embedded grid layers to be saved to workspace files without errors.
Fixed issues loading from WMS sources where the GetMap URL includes a question mark.
Fixed issue in v13.1 with Global Mapper Grid exports with large no-data areas filling those areas with 0 when zoomed out.
Fixed issue in v13.1 with layer selection not working for all PDF files.
Fixed more issues loading DGN files with curves as part of the outer boundary of an area shape.
Fixed issue with exporting 3D area and line features with elevation units other than meters to vector Lidar LAS files. The elevation units were not converting correctly.
Fixed issue with the MapMart Data Discovery Tool from the online source not working on 64-bit Windows.
Updated E00 import to include the level for annotations as an E00_TEXT_L attribute for the point feature created for the annotation.
Fixed issue in PDF export with Map Layout margins overriding PDF export margins and sometimes obscuring other map layout layers, like custom text.
Updated grid line export to PDF files to only show those grid lines appropriate for the export resolution rather than always exporting all grid lines.
Updated PDF export using the source filename/layer description for the PDF layer name to prepend the group name assigned to the parent layer for a feature to the layer name in the PDF file.
Fixed error in v13.1 when loading some types of files with non-English letters in the filename.
Fixed error in v13.1 that caused no data to be loaded from Lidar LAS/LAZ when saving to a workspace and reloading or placing in a map catalog.
Fixed bug in v13.1 where the DPI was not being saved for GeoTIFF exports.
Fixed loading of accented characters from UTF-8 encoded GNIS text files.
Fixed error loading some Arc ASCII Grid (GRIDASCII) files from v13.1.
Made KML/KMZ files which contain NetworkLink elements referencing KMZ files automatically download and load those KMZ files. Previously only linked KML files would work.
Fixed issue when exporting Shapefiles from features with different attribute sets with multiple attributes over 10 characters in length with the first 10 characters being the same.
Added Check All and Clear All buttons to many dialogs with a list of things that can be selected.
Added support for specifying an override of the rectification method inside a GCP file with a line of format Method=method_name, like Method=Polynomial, or Method=Affine.
Fixed issues adding WMS sources with a ? at the end of the URL.

Fixed problems parsing degree projection attributes from GeoPDF files that aren't just straight decimal numbers (i.e. ’69 W’ rather than ‘-69’).
Allowed Equidistant Conic B projections to be saved to WKT PRJ files.
Fixed problems in v1.37 release with Old Israeli Datum, MGI Croatia-Serbia, MGI Slovenia, Kertau 1948 (Malaysia), and S-42 (Azerbijan/Georgia) datums.
