I've been trying to plot the GPS points that I've taken using a Garmin GPS device on the BING maps basemap in ArcMap 10. This is proving to be difficult.
Unfortunatley, I do not know the coordinate system of the coordinates and do not have the GPS device to check.
That is a sample coordinate and cutting and pasting that in to Google Earth plots exactly the correct point. Looking at the Properties of the point, Google seems to do some conversion to this. (Should display the coast of Sal,Cape Verde.)
Can anyone offer any advice on how to proceed? I want to plot the points in ArcMAp and use the Bing Maps Base map.
