A simple web app to show geo coordinates in two different coordinate reference systems (CRS).
Live at https://cartolab.at/coords/
Buildless monolithic no-framework app, you find everything in index.html.
Node stuff is only used for the script makeCSV.js, which is used to generate allEPSG.csv
containing the metadata for all CRS. If you want to run this script yourself for some reason, run npm i first to install the necessary Node modules.
Upon selection of a CRS in the app, its full data is loaded from the file in crs_data.
