Blue Marble Releases Global Mapper SDK v15 Featuring New Mathematical Raster Calculator

Hallowell, Maine – November 6, 2013 - Blue Marble Geographics ( is pleased to announce the release of the Global Mapper Software Development Kit (SDK) version 15. This release offers many new features and functions including a new mathematical raster calculator, LiDAR analysis tools, 3D PDF read/write support and much more. Blue Marble's geospatial data manipulation, visualization and conversion solutions are used worldwide by thousands of GIS analysts at software, oil and gas, mining, civil engineering, surveying, and technology companies, as well as governmental and university organizations.

The Global Mapper SDK provides a Windows DLL, which allows users to include much of the functionality of Global Mapper within their own software applications. The SDK includes both native 32-bit and 64-bit DLL’s, so users can target any Windows operating system. The new raster calculator in Global Mapper SDK v15 features mathematical operations for work with multi-band imagery for extracting and leveraging a variety of information from the imagery. Users can use pre-defined formulas, like NDVI (Normalized Difference Vegetation Index) and NDWI (Normalized Difference Water Index), or create custom free-hand formulas using common mathematical operations, like addition, subtraction, multiplication, division, and powers, as well as simple operators like absolute value, minimum value, and maximum value of two values.

We encourage all geospatial programmers to take a look at the Global Mapper SDK,” stated Blue Marble President Patrick Cunningham “Whether you’re looking for additional functionality for your software product or a custom project, the tool is powerful and easy to use, and for LiDAR, there is nothing like it on the market today.”

This release also features the ability to edit and re-calculate multiple view shed layers and 3D PDF read/write support. Additional features included are scripting enhancements such as passing variables to the script from the command line. The Global Mapper SDK v15 release includes a new binning method for gridding LiDAR point clouds. Users can now 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.
