Blue Marble Geographics Releases Version 24.1 of the Global Mapper Software Development Kits

Hallowell, Maine – March 21, 2023 – Blue Marble Geographics® is pleased to announce the immediate availability of version 24.1 of the Global Mapper® and Global Mapper Pro® software development kits (SDKs). The updated SDKs include new features and updates mirroring the recently released desktop applications.

Both software development kits allow developers to utilize functionality from Global Mapper in their own applications and create custom toolbars and extensions for the latest versions of Global Mapper.

The standard version of the Global Mapper 24.1 SDK includes a new function, GM_FindLoadedLayer, which takes a string argument, searches for any layers with a matching description attribute and returns that layer’s 32-bit handle.

The Global Mapper Pro SDK also includes the new and enhanced features available in the standard version, including the ability to apply convolution filters to an existing raster layer that can be used to sharpen, blur, enhance, or help detect edges. Contour lines can also be generated directly from lidar layers without elevation grids. 

“This latest Global Mapper SDK release further expands the SDKs functionality with new and exciting tools,” said Jeff Hatzel, Product Manager. “Whether that’s advanced raster analysis by working with custom convolution filters, or various improvements to lidar workflows, the SDK continues to expand to suit the wide variety of needs of its users.”

With opportunities to use the engine behind Global Mapper in custom applications and tools, the Blue Marble software development kits are a valuable resource for organizations worldwide.
