New Features in the Global Mapper SDK™

Latest Changes

New in v19.1

Significant New Features

  • Improvements in the GM_DrawLayerList process with multiple threads called simultaneously rather than one thread at a time
  • Support for reading and writing LAZ (LasZip) files with the LAS 1.4 fields
  • Support for importing and exporting AutoCAD 2018 DWG files
  • Addition of several new UK online data services

New Features in the LiDAR Module SDK

  • A scripting option for generating a point cloud, orthoimage, or 3D mesh from overlapping UAV images
  • Automatic spatial point cloud sorting resulting in faster rendering and analysis

New in v19

Significant New Features

  • Significant expansion of the built-in online data sources for the U.S States and Canada
  • Support for importing and exporting several file formats including GPX, KML, and ASCII text when creating simulated fly-through recordings

Advanced LiDAR Functionality

  • Improved recognition and reclassification of ground points in LiDAR and other point cloud datasets
  • New option to grid a point cloud based on color values resulting in a raster orthoimage layer

New in v18.2

Significant New Features

  • Support for Amazon Web Services (AWS) Amazon Simple Storage Service (S3) Open Cloud Datasets which allows sources to be imported from S3 buckets and data formats can now be exported to writeable S3 buckets [available via scripting in SDK]
  • New built-in sources for the 1-arc-second (30m) resolution SRTM and ESA CCI Land Cover data for the entire world
  • Export feature attributes to DWG and DXF files
  • New 3D fly-through playback loop option
  • Improved lighting model for display of vector features and models in the 3D Viewer

New in v18.1

Significant New Features

  • New managed component for .NET users - this wrapper adds utilities for commonly used classes and simplifies the memory management details when using the Global Mapper SDK with Microsoft's .NET Framework
  • Improved error reporting when SDK functions experience a Windows exception, such as an access violation
  • New warning messages when certain raster formats cannot be imported due to the required library DLLs not being loaded
  • Significantly improved usability/speed of model and raster display in 3D View with large amounts of data loaded
  • Significantly sped up display and other operations on vector data sets, including significantly faster load of large shapefiles
  • Support for many new formats, including LandXML(export), RMaps/MBTiles (import), BPF Lidar (import), Autodesk FBX (import/export), and GSF (import)
  • Improvements to 3D fly-through creation, including the ability to apply a bank angle value to each flight segment, to vary the fly-through velocity for each segment, and to record and save multiple fly-through paths at once
  • Numerous online data source updates including replacing 1-meter NAIP Imagery with 1-foot National Map Imagery using new USGS National Map server and the addition of GEBCO (General Bathymetric Chart of the Oceans)
  • New script command CALC_VOLUME_BETWEEN_SURFACES for measuring the volume between two surfaces
  • New option to automatically reformat Shapefile (DBF) numeric attribute values using scientific notation as normal decimal numbers (GM_MiscOpt_ReformatDbfNumbers)
  • New function to calculate color statistics within an area

New in v18

Significant New Features

  • Improved 3D viewer, particularly in regards to LiDAR and raster/terrain display
  • New Lidar access methods for quickly reading and writing large LiDAR point clouds
  • Dramatically faster display and export of most raster/terrain formats, especially with large amounts of loaded data
  • Improved thread-safety of low-level raster/elevation layer access, making it possible to concurrently access and draw the same layers in multiple threads
  • Support for importing PDF files as vector layers
  • Support for importing and exporting OGC GeoPackage files

New in v17.2

Significant New Features

  • Significantly faster exports of multiple tiles to raster (image) and web formats
  • Support for pan sharpening color imagery using higher resolution panchromatic (grayscale) imagery
  • Option to specify the DPI value when loading PDFs
  • Support for saving imagery layers within Global Mapper Package files in JPEG 2000 format, drastically reducing the file size
  • Faster import of text-based file formats

Advanced LiDAR Functionality

  • Significantly reduced the memory requirements and increased draw speeds for Lidar point clouds loaded from text-based formats

New in v17.1

Significant New Features

  • Support for querying and changing Lidar classification info (name, color, groups) using the new GM_GetLidarClassInfo and GM_SetLidarClassInfo functions
  • Support for loading text files with multiple coordinate pairs on a single line of the file, such as TINs in simple text and 2-point paths on a single line
  • Reduced load time for Lidar point clouds, GMP files in particular
  • 3D PDF export via the EXPORT_PDF3D script command (use GM_RunScript function)
  • Allow high bit depth JPEG2000 files to be exported from the 64-bit version of Global Mapper SDK.

New in v17

Significant New Features

  • Dramatic speed improvements for all data types but especially Lidar and 3D ranging from 40% to 10 times faster depending on number of cores and processing power
  • Support for using 3D point styles to render graphically pleasing objects like trees in 3D
  • Several new built-in online sources, including US National Map sources (w/ 1 foot color imagery source), World Navigation Charts (1:1M Scale ONC Charts), and Australian water sources
  • Updates to GPS Tracking, to support Glonass and Baidu NMEA positions, as well as new tracking functions to follow the live position more closely and orient the map to the GPS Heading
  • Export of 3D data formats, including PLY, OBJ, and Collada (DAE), and STL

Advanced LiDAR Functionality

  • Automatic classification and feature extraction for Power Lines
  • Automatic classification of high and low noise points
  • Calculation of basic rooftop statistics from point clouds
