hey, the GIS layers are great, the Wilderness boundaries especially. I was able to download the files just fine on my home computer. On my work computer I get a TopoFusion error = -1. What is that?
-
Best guess is that the request is being blocked by a firewall.
The GIS layers are downloaded from topofusion.com itself, not from Terraserver and OnEarth (sites that were likely permitted for the application to access).
-1 just means the download failed. I'll make the error message more informative and have it suggest a firewall problem.

Can you tell me which urls should be let through the firewall for full functionallity? I've opened:
topofusion.com
terraserver-usa.com
onearth.jpl.nasa.gov
I still have trouble receiving tiles much of the time and get messages from TopoFusion about trouble contacting the server and alerts from my router/firewall like this:
Message: SYN Flood to Host
Source: 192.xxx.xxx.xxx, 1200
Destination:65.54.135.103, 80 (from WAN Outbound)
that seem to corespond to the TopoFusion error messages. Thanks for any help - love the program!

Those three servers are the only ones needed by TopoFusion. TF.com is only needed to download the GIS layers.
That error message indicates an attack on your IP. See:

I have never heard of the tcp requests being sent by TopoFusion causing such an error. But it is possible there is a setting on your router that is too sensitive for this kind of thing.
Good luck.

I was getting this error too. My firewall was proxying the request and and denying it with the error "No URI Found". I added just a filtered, non-proxied HTTP rule for my machine and the download went through.
