Hi, OSM uses EPSG:4326 for storing coordinates and EPSG:3857 for rendering.
You can get projection definitions on http://epsg.io/4326 and http://epsg.io/3857 respectively, or find it bundled with proj4 library that is widely used to deal with projection nuances. сб, 18 июн. 2016 г. в 1:37, Stadin, Benjamin < [email protected]>: > Hi, > > I want to double check the earth radius used by OSM and zoom levels is > exactly 6372.7982 as said here: > http://wiki.openstreetmap.org/wiki/Zoom_levels. > > I couldn¹t find this as constant in the sources yet.
