I've been trying to combine two different sets of map data into one and have had nothing but trouble doing it.
I am using GPSMapEdit and CGPSmapper as editing and generating software.
It seems that when I combine both sets of map data and compile it into a usable image there are roads and points missing from the finished product. I do not have this same issue when I make the maps separately. The data I do have will route as it should but I want to have all of it, not just 75-80%.
Any clues as to how I can remedy this situation? Help, or guidance, is greatly appreciated.
