• C#

This is a simple to use Geodetic Library for .Net that will allow simple transformation to and from British National Grid.

• UpdatedOct 2, 2025
• C#

A test suite of ECEF-to-geodetic coordinate conversion functions

• UpdatedOct 22, 2025
• C++

This is a C++ library meant to provide implementation of the most commonly used geodetic algorithms.

• UpdatedAug 5, 2025
• C++

Accurate Conversion of Earth-Fixed Earth-CenteredCoordinates to Geodetic Coordinates (ecef2lla/lla2ecef) with Python bindings

• UpdatedFeb 20, 2021
• C++

Coordinate Reference System Transformations. This is a .NET library implemented with F#, but also usable from C#. Most of the test code is actually written with C#. The third-part libraries used from the F# code may also have been implemented with C#.

• UpdatedNov 9, 2021
• F#

Essential transformations for PTZ units and conversion between global coordinate systems

• UpdatedSep 15, 2021
• Python

Coordinate Reference System Transformations. This is a "JVM library" implemented with Kotlin, but usable from e.g. Java/Kotlin/Scala/Groovy/Jython/JRuby (see the sample code). Most of the test code is written with Java, and the third-part libraries used from Kotlin are also implemented with Java.
