Hi,  
I have one point layer.And i render that layer using below projection as given in Sample. It is located correctly.Below are points and projection.  
Latitude: 17.89066966 Longitude: 74.74236948  
Proj4Projection proj4 = new Proj4Projection(4326, 3857);  
proj4.Open();  
PointShape pointShape = (PointShape)proj4.ConvertToExternalProjection(new PointShape(74.74236948,17.89066966));  
Now i am plotting user defined points on google map.So I get e.Position.X,e.Position.Y points.  
My point is: e.Position.X: 8319149.5 , e.Position.Y: 2025495.25  
But when i show these points using above projection on map, the points are not displayed on map.  
How do i convert above points in Latitude n longitude format?  
How do i show this point on map?

Regards,  
Mouni

Thanks Mouni,  
Google map using 3857 projection which is meter unit. The way you using to convert the coordinate is correct. If you want to put the decimal degree to the google map. You need convert it to the 3857 first. Then add it to the map. Could you attach your sample code/project here which could help me understand the issue.

Thanks

Frank

Thank you for your reply.

Thanks
