| GPS coordinates I got from a GPS device, a string including lat and long coordinates but it is not in a format that GETLOCATION recognize. It looks like "...,4648.914,N,7113.7715,W,..." What can I do with it? Formulas?         |

| Re: GPS coordinates
Hi, This is NMEA0183 format. To compute it into the format mappoint need is very simple. I explain: The format you have is for latitude: ddmm.ffff and for longitude: dddmm.ffff and N/S, E/W is the hemishpere. dd(d) are the degrees mm are the minutes ffff are the fractions of the minutes So you exctract the degrees (2 char's for latitude, 3 for longitude) and add them to a double. Then you thake the minutes including fractions (watch that the decimal separator mach your computer's locales or workaround it), divide it by 60 and add it to the degrees. Then check the hemishpere. S - beyond equator so latitude = -latitude, and W is left of meridiane, so longitude = - longitude.
