Hi Khalil Thank you for the reply. Basically I just want to use one projection which is Epsg 32737 and I am not interested with google overlay but I just use it to test my point. So can you use the shape file as base overalay. I so far don’t know the projection of the point from my device and that’s why I am seeking help from you. But we have both found that, the mobile device’s point is plotting well on google. I think the challenge is, how can we use this finding to make the point overlay well with the shape file.
