Hi, See -
getProjection public Projection getProjection() Get a projection for converting between screen-pixel coordinates and latitude/longitude coordinates. Returns: The Projection of the map in its current state. You should not hold on to this object for more than one draw, since the projection of the map could change. in the MapView class refer - http://code.google.com/android/add-ons/google-apis/reference/index.html Regards On Jan 19, 2:38 pm, prachi <[email protected]> wrote: > Iam sorry but Iam not aware of UTM lattitude and longitude nad how is > it different from the normal one.Iam not using google maps..Its an > application where in for a particular screen coordinate I need to get > the corresponding world coordinates(reverse of projection) and from > there fetch the latitude and longitude value of that fix. > > As said by Kostya I will go through unprojection. :) :) > > On Jan 17, 11:25 pm, Larry Mackey <[email protected]> wrote: > > > > > > > > > What world coordinate system are you using (UTM, Latitude and > > Longitude, ???)
