I am looking for a tool that is able to generate coordinates and convert them into different systems.
Generation of coordinates: the tool should display a map (like Google Maps or OpenStreetMap) and let me pick a location. Also the opposite functionality should be supported: enter a location and navigate there on the map.
Conversion of coordinates:
- decimal degrees <-> degrees + decimal minutes
- decimal degrees <-> degrees + minutes + decimal seconds
- WGS 84 <-> any supported coordinate system
- Grid Square Locator <-> any supported coordinate system
- perhaps some of the other 7403 coordinate systems
- compare two coordinates and find the difference between them (shortest air line distance between two points)
It seems I want something similar to https://epsg.io, just offline.
