Archived Support / aerial photo

Here's another vote for implementing user maps in TF.  It would save me a lot of time and effort to add at least one user layer to the photo and topo layers.  I have two immediate uses for this requested feature.

1)  I could scan plat book pages for use during real time tracking so that I can verify that I am exploring public lands and not trespassing on private land.  Currently, I've painstakingly plotted public land boundaries by hand drawing tracks around each section's (square mile) acreage.  I have plotted over 700 parcels of public land by hand just in my area of Michigan and would like to use user maps instead for future public land endeavors.

2)  I could scan maps available for recreation areas, such as Isle Royale National Park, that contain information not available on the USGS topo sets.  There are many paper maps available that it is impractical to duplicate their information for TF use that the user maps feature would enable, ie park trail systems, facilities locations, parking areas, etc.

Thanks for TF and your efforts thus far.

I've cleaned up the files and deleted some of the duplicates.  I now find that I can successfully generate a network if I exit the program and restart it each time I generate a network.  If I do not restart, any successive (second) attempt to generate a network results in the above error and the program must be shut down anyway.

I've emailed a .zip of the files in question.  It's kind of a mess of data collected over the last few years using differing equipment and methods.  The network has failed to generate on a different PC, although it did look encouraging after the first try was successful.

While you look at this, I am going to try to manually clean up some of the tracks and see if that helps the situation.

Topofusion v2.1

I am getting an error about 90% of the time I try to generate a network using a given set of tracks.  I can successfully generate a network some of the time using default settings or by maximizing both contraction and reduction.  The rest of the time I get the following error dialog:

Topofusion
Exception: Access Violation, in Manager Thread (Network)
OK

After this error, there may also be a paint error.  In either instance, the program display is unresponsive following the error(s) and the program must be restarted to regain functionality.  Where do I go from here?
