diagnostic analyses and calculations in contour-based coordinates
Astronomical space coordinate and time conversion. Calculate Julian day, local sidereal time and ecliptic obliquity with great precision.
A small and efficient single-file, header-only library written in modern C++ library to test whether a coordinate is inside a polygon to realize, for instance, WGS84 geofencing.
A Java library for representing latitude, longitude and cardinal points of the compass, and calculating distance and bearing between points
坐标转换，包括 * 各地图API坐标系统比较与转换; * WGS84坐标系：即地球坐标系，国际上通用的坐标系。设备一般包含GPS芯片或者北斗芯片获取的经纬度为WGS84地理坐标系, * 谷歌地图采用的是WGS84地理坐标系（中国范围除外）; * GCJ02坐标系：即火星坐标系，是由中国国家测绘局制订的地理信息系统的坐标系统。由WGS84坐标系经加密后的坐标系。 * 谷歌中国地图和搜搜中国地图采用的是GCJ02地理坐标系; BD09坐标系：即百度坐标系，GCJ02坐标系经加密后的坐标系; * 搜狗坐标系、图吧坐标系等，估计也是在GCJ02基础上加密而成的。
A collection of libraries to convert between Latitude / Longitude and map grid references, particularly the Ordinance Survey National Grid

Small tool to coordinate volunteers and meetings — 📆🗃
ProjNet4GeoAPI-For-Unity allows immediate processing of geo-coordinates in the Unity game engine. The package is provided as a Unity package (UPM) and also integrates and relies on the commonly used C# conversion library ProjNet4GeoAPI.
Detects country by given coordinate
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#.
