How can I merge .map files in Global Mapper?
How can I merge two maps from blue part in the attached photo of maps in Global Mapper? These two maps are from 2 different sources but I need them to combine..
It's hard to recommend any workaround without seeing the data. The gap is quite large so the Join function might not work as adjacent contour intervals look much closer. Maybe you can create an infill piece by gridding the data you already have (group the layers and grip the group)? Then create contours with the same intervals as your source. You could then crop the contours a little short of the gap and try the Join Function to join them all together (using an appropriate gap tolerance).
Sorry I meant grid the group not grip the group.
