This looks like a good place to add a plug for support for "user supplied" map data - scanned jpg, gif, tif, or whatever format. This is the only significant feature ExpertGPS has over TopoFusion right now. I'm finding it absolutely invaluable when exploring new areas using old paper maps of "lost" trails! I've been doing this a lot lately - very fun!
In fact, TopoFusion could get one leg up on ExpertGPS by improving the calibration procedure when adding this feature. All it would take would be an easier way to obtain the coordinates of a calibration point from another downloaded reference map. These have to be entered manually in ExpertGPS right now. This is error-prone & time consuming, usually involving a pencil & paper. It would be nice to be able to just go to the calibration point on the reference map (TF topo layer for example) & just right-click "copy coordinates", then go back to the scanned map layer & paste those coordinates!
Better yet would be to right-click on the user map to "add calibration point", switch layer to reference map, right-click "set calibration point" on the reference map, repeat for all 3 calibration points! That would be really much faster & very cool!
Maybe just have a calibration point tool where a calibration point is similar to a waypoint in that you simply click on the map to create it except it is layer specific. To align the calibration points between a user-map & reference map, the user could simply give the points the same name in a properties dialog or something?
Lots of ways to do the calibration I suppose, but something simpler & faster than ExpertGPS uses would be greatly appreciated. User maps are a GREAT feature, but the calibration needs to be simple & fast!
So can TF beta this feature before my trial of ExpertGPS runs out in 15 days?
