A zero-dependency Go package for coordinate transformations.

Fast, accurate WGS84 ⬅️➡️ OSGB36 (OSTN15) conversion, using Python and Rust

A multithreaded Rust library with FFI for converting WGS84 longitude and latitude coordinates into BNG (OSGB36) Eastings and Northings and vice versa (using OSTN15)

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

A set of methods focused in performing the OSGB36/ETRS89 transformation (Great Britain and the Isle of Man only) by using the Ordnance Survey's OSTN15/OSGM15 transformation model. Calculation of distances and areas from sets of points defined in any of the supported Coordinated Systems is also available.

A Rust crate providing Ordnance Survey OSTN15 adjustments for ETRS89 coordinates

A .Net wrapper for GridInQuestII, written in C#.

Fast, accurate conversion of WGS84 [longitude,latitude] <-> OSGB36 (OSTN15) [eastings,northings], in Julia

Delphi coordinate conversion inspired by http://www.movable-type.co.uk/

Convert a csv of data in OS grid references to OSGB36 eastings and northings
