change map default projection

Jan 9, 2008 at 1:28 PM
i'm using sharpmap 0.9 and adding layers programaticlly using VectorLayer and List<Geometry> as DataSource . i create all geometries in my application then i'm using Map.GetMap(). i know that the default projection in sharp map for long/lat data is plane Caree, my problem is that i want to change this projection to be UTM. i tried to do that by asigning each Geometry i create a SpacialReferance which is a UTM Projection. but it seems not working.

my question is how to do that.

thanks in advance.
