How to pass coordinates via URL

You can have TWCC open with the marker set to a specific location and the converter set with specific systems.

First you must have at hand 4 pieces of information:

<lng>: WGS84 longitude, in decimal degrees, e.g.: -113.39
<lat>: WGS84 latitude, in decimal degrees, e.g.: 31.85
<sc>: Source CRS/system code, e.g.: wgs84
<dc>: Destination CRS/system code, e.g.: EPSG%3A25831 (%3A is the URL-encoding of colon :)

Then write the URL as follows:

https://twcc.fr/?wgs84=<lng>,<lat>&sc=<sc>&dc=<dc>

With the provided examples it would look like this:

https://twcc.fr/?wgs84=-113.39,31.85&sc=wgs84&dc=EPSG%3A25831
