Search coordinate systems

This page shows how to search coordinate systems using our Coordinates API. You can also use this service with the API client JS.

For a beginner intro into the service, see Work with coordinate systems.

The universal search URL format is:

https://api.maptiler.com/coordinates/search/{QUERY}.json?{PARAMS}&key=YOUR_MAPTILER_API_KEY_HERE

Parameters	Description	Example
QUERY	Query on CRS	2056.json swiss.json czechia deprecated:1.json
PARAMS	Parameter for showing exports in WKT and Proj4, limit the number of results of show transformations.	swiss.json?limit=1 exports=true&limit=5

Example
