Mobile coordinates

[swimming123]

Hi all,

Recently I try to make a map to be displayed in mobile web. My first question is what coordinate system I can use? Any options? Can I use UTM system or I have to use web mercator?What if I don't include base layers like Bing, OSM? Thank you.

If you're not integrating with OSM/Google/Bing layers then you can use whatever coordinate system you want really.

Otherwise you have you use web mercator if you want the OSM/Google/Bing layer to line up with your map
