Release of the GeoCalc Software Development Kit (SDK) v9.3

Following the updates to Geographic Calculator 2025, and the release of Geographic Calculator Cloud, the new GeoCalc v9.3 SDK includes new features and updated geodetic definitions to keep your applications on the cutting edge. The GeoCalc Software Development Toolkit (GeoCalc) is a fully object-oriented library designed for GIS professionals and software developers. GeoCalc SDK version 9.3 includes new EPSG definitions, an update to the HTDP transformations, the addition of several geoid models, and support for the .NET 8 framework.

The most powerful upgrade arriving in GeoCalc 9.3 is support for Microsoft .NET version 8. The latest .NET platform provides developers with access to a cross-platform framework and is accessible with many modern development tools and languages including C#. Version 8 was released in 2023 and most notably provides support for C# 12 alongside other improvements to performance and its libraries. GeoCalc has previously supported versions 4 and 6 of the .NET framework.

In addition, the C++ and C# versions of GeoCalc 9.3 will include all the enhancements in the Geodetic Datasource from the recent release of Geographic Calculator 2025, as well as a tidy fleet of enhancements and improvements.

What is GeoCalc?

Often used with GPS, surveying, engineering, and mapping systems, GeoCalc provides users with high accuracy and dependable coordinate conversions, transformations, and geodetic calculations. GeoCalc employs a high-level parametric database model to efficiently store and retrieve coordinate reference systems, area-of-use details, ellipsoids, geodetic transformations, unit parameters, and everything else that is needed for advanced geodetic software applications.
