A library designed to ease geographic coordinate format conversions, and determine sun/moon information in C#

QGIS tools to capture and zoom to coordinates using decimal, DMS, WKT, GeoJSON, MGRS, UTM, UPS, GEOREF, ECEF, H3, and Plus Codes notation. Provides external map support, MGRS & Plus Codes conversion and point digitizing tools.

Simulation of the full GPS stack, from satellites' transmission to position calculation at receivers

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

Simple, precise, accurate and fast Geographic/Cartesian coordinate transformations via C++ header-only implementation.

Simple geo coordinates conversion library

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

Essential transformations for PTZ units and conversion between global coordinate systems

Two Line Element position calculator using sgp4

Geodetic calculator (Geodetic tasks - direct and inverse; conversions between Geodetic, ECEF, ENU, AER, SK-42; Bursa-Wolf 7-parameters ECEF to ECEF)

This library provides different coordinate systems

QGIS tools to capture and zoom to coordinates using decimal, DMS, WKT, GeoJSON, MGRS, UTM, UPS, GEOREF, ECEF, H3, and Plus Codes notation. Provides external map support, MGRS & Plus Codes conversion and point digitizing tools.

The envector package is a suite of tools written in Python forked from the nvector package to solve geographical position calculations powered by means of n-vector.
