General notes for getting the most out of gmap. COMMONLY USED COORDINATES ------------------------- 37.0625,-95.677068 -- Center of US according to Google THINGS TO WATCH OUT FOR ----------------------- A) Be careful when using extremely long line segments. Due to the way distance computation works in the Google Maps API, long segments have a tendency to "invert" themselves (i.e. come onto the screen from the opposite east/west direction.) You can work around this issue by adding additional points.
