This is a C# class library containing some very basic geodesic algorithms. It is based on work by Mike Gavaghan and has been enhanced by me to cover also some variants of Mercators projection of the earth to flat maps. I cover Spherical and Elliptical Mercator projections, mapping the earth to a single flat map. I also handle the Universal Transverse Mercator (UTM) projection, dividing the earth into smaller grids which are then each mapped to a flat map. Finally - based on UTM - I implement an algorithm to put a finer grain mesh over the mapped area of the earth to be able to classify a geo-location by a discrete globally unique mesh number. This is done in order to facilitacte the application of some discrete algorithms - especially in the area of machine learning - on geo locations.
You can translate both ways between coordinate systems: RT90, SWEREF99 andWGS84. The WGS84 object can parse out positions from strings in DMS (degrees, minutes seconds, and DM (degrees, minutes) format. All in all it’s a pretty easy to use and powerful library.
CoordinateSharp is a high-performance, lightweight .NET library for working with geographical coordinates. Effortlessly convert coordinates, compute distances, and calculate location-based solar, lunar, and magnetic data — all with minimal code.
Premium data set for generating map data. Mapping locations, point of interests, and GPS data for your applications, UIs and databases.
Magnetic data extensions for CoordinateSharp. Provides magnetic declination, variation, and related geomagnetic calculations based on geographic coordinates.
A professional geodetic calculation libary about coordinate system's definition, conversion, projection, transformation functions of geodetic datum such as ITRF, WGS84, BDCS, ETRS, etc. This is a C# .net standard class library containing some professional geodetic algorithms on ellipsoid supports json data shared by Zhengzhou Insititute of Surveying and Mapping. Geodesy.Datum defines the basic angle/latitude/longitude data type which can be simple serialized or deserialized to json. There are all different coordinate data type such as astronomic coordinate, geodetic coordinate, space rectangular coordinate, projected coordinate, spherical coordinate, etc. The libary provides the functions of all types of coordinate conversion, geodetic calculations on ellipsoid surface, geodetic problem solutions, Gauss projection and UTM (MGRS, UPS), geodetic datum transformation.
A small library with helper methods to convert between WGS84 and RT90/SWEREF. Also has utilities to calculate distances between coordinates.

Coordinate Reference System Transformations core API library e.g. defining the interface implemented by adapters. F# library (usable from .NET e.g. C#) for transforming coordinates between different coordinate systems. The core assembly provides an adapter interface which is implemented by other assemblies using different third-part libraries as adaptees.
