I have an idea for user maps. I don't know a thing about the inner workings of TopoFusion, but I am a thinker... So I'll leave it to the developers as to whether the idea has any merit.
After adding a 10 MB JPEG there was a noticeable decrease in performance. Chopping it into 4 different images and scaling it down to fit within my graphics cards maximum texture size helped, but there still seemed to be a performance hit.
If I use the user maps feature as much as I suspect I will, I anticipate performance problems.
So what if after the user maps were converted to another tile set? The different tile sets are absolutely huge (covering most of the earth at varying resolutions) and scale very well. Can the same approach be used for additional maps?
I am absolutely giddy to have found all of the trail maps for the state of Utah in PDF format (
http://www.stateparks.utah.gov/ohv/maps.htm). I plan to import them all as user maps. I'll let you know how it goes.
Anyway, just a thought.
Thanks for the great software.
