I downloaded data from OSM and extract lat/lng coordinates from a user who is clicking on a
leaflet map. So my program returns the coordinates where a user clicked!
I am wondering what
crs I need to assign them?
What I see on the screen is Web Mercator (EPSG 3857). The data I download from OSM is in WGS84 (EPSG 4326)?
Everything in Web Mercator (EPSG 3857)
What I am wondering is what CRS I need to assign to the downloaded OSM data and the data I get returned in my program from leaflet.
