Hi All
I need a hint again please.
When I plot a TIN Model (Triangles) on Googlemap, I find that there is a limit on far I can Zoom in. It looks like it's a Factor of about 25.
When I plot the Contours as well, I need to be able to Zoom in close to enable me to select the correct side of a Triangle that needs to be swapped, in case the Contours are not drawn correctly.
Is there a way to bypass this limit?
