Load Maps and Display Data

With the Global Mapper SDK, load any number of layers from almost all of the formats supported by Global Mapper. This includes nearly all imagery, elevation, and vector data formats. The SDK can be used to load data from online WMS sources, including built-in access to NED, SRTM, and Landsat7 sources (among others). It can even load imagery that has not been georeferenced by providing ground control points and projection. The DLL will perform the rectification and display the raster layer in the appropriate projection.

Manipulate and Analyze Data

The Global Mapper SDK can be used to initiate a variety of spatial data analysis procedures:

• Determine the elevation at any location from loaded elevation layers
• Retrieve information about loaded layers, including projection/datum, bounding rectangle, description, ground control points, pixel size, etc.
• Generate contour lines from loaded elevation grid layers
• Calculate cut-and-fill volumes along a given line or within an area
• Reproject loaded data to a user-specified projection/datum
• Auto-clip the collar from USGS DRGs
• Reproject coordinates from one projection/datum to another projection/datum
• Modify the drawing style and font of all loaded vector data, including your own custom vector layers
• Perform a position-based search of loaded vector data (similar to the Feature Info tool in Global Mapper)
• Calculate the volume between 2 terrains as well as find ridge lines on loaded terrain data
• Automatic classification of ground points from unclassified LiDAR point clouds.
• Dramatically faster gridding of point cloud data and support for min/max/average gridding operations on Lidar point clouds.
• Display Lidar points by height above ground to visualize vegetation and building heights.

Spatial Database Support

As well as providing access to spatial data files, the Global Mapper SDK offers the option to read and write data to a spatial database. Import and export data from:

• Esri ArcSDE (requires Esri license on machine and 32-bit only)
• Esri File Geodatabase (includes raster and grid and all versions of file geodatabses, requires Esri license on machine and 32-bit only)
• Esri Personal Geodatabase (requires Esri license on machine and 32-bit only)
• MS SQL Server
• MySQL Spatial
• Oracle Spatial
• PostGIS/PostgreSQL
• SpatiaLite/SQLite

Work in 3D

The Global Mapper SDK provides the ability to display the Global Mapper 3D view with loaded terrain and 3D vector features along with any other data draped on top of the terrain surface. It can also retrieve the elevation at any location from loaded elevation layers and it can even perform view shed analysis using loaded elevation grid layers as well as vector data (areas, lines, and points) with elevation values associated with them.
