Hi,
a dummy question, but I am just not too familiar with map datums.
I live in Ecuador and ususally use the maps of the IGM (Instituo Geografico Militar). They are all based on the Provisional South American 56 datum, except for, as it appears, the Huaca map which uses WGS 84. I had not realized this in time, so my GPS was set to Prov South American 56, as usual, when recording a couple of tracks in the area of the Huaca map.
My questions is: when loading my tracks onto the maps in TTQV what do I have to do to adjust for the different datums? Or can I not use the tracks with the map at all?
Many thanks
Sonja
