Երկիր (Erkir) - a C++ library for geodesic and trigonometric calculations

A .NET library that provides strongly-typed implementations of multiple coordinate systems, including rectangular, polar, spherical, and geodetic.

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

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

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

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

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#.

Essential transformations for PTZ units and conversion between global coordinate systems

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.

A software package designed for estimating historical ship tracks utilising either Kalman filters or Gaussian processes.
