Reference System in Google Maps Api

Postby Mathias » Wed Nov 25, 2009 6:05 pm

Hi,

which Spatial Reference System is used by the Google Maps API and in which Reference System are the GPS coordinates to be received by a LocationProvider?
I only can assume that the Location Services use WGS84, or EPSG:4326. But what if I use GeoPoint? Will it require WGS84 or the Google Maps Projection (some kind of traverse mercator projection EPSG:90913). And what reference do the Projection.fromPixels(..) and Projection.toPixels(..) methods require?

I ask because I want to display some GeoData to an Overlay and I have to decide in which reference system I have to request it from my Services.

Kind regards

Mathias
