TOPO North America is okay.
It lets you do most of the things you were able to do with the Nat Geo software. The DVD has coverage of all of the US for $99.00, but the detail and contour lines are not as good as what you got on the Nat Geo states series. I think for $30.00 per year, you can have unlimited access to download the 1:24,000 imagery off of the DeLorme servers.
However, I still found that printed output of the Nat Geo software was better, especially at 1:50,000, than the Delorme TOPO NA software. 1:50,000 was the scale I liked best. On an 11x17 map, it was the best compromise between area coverage and detail.
I'm preparing for a trip to the Wind River range in WY next year, and couldn't find the WY DVD, even on E-Bay, and was not happy with the Delorme printed output.
Here's what I need and can't get out of Alltrails.com or hillmap.com. Maybe some of the features are in one or the other, but not both:
UTM grid Draw routes, measure distances along the route, and generate printable elevation profiles and stats (vertical climb, vertical descent, elevation gain, distance). Export the routes to .gpx format. I then transfer them to Google Earth and Google Maps to view and discuss during the group trip planning discussions. Print at a scale that I specify, so that I can use a UTM plotter in the field.
What I ended up doing is creating my own map using the free USGS 1:24,000 imagery. I had to manually stitch four quads together in a "Photoshop" like application, then scale and crop out the section I needed. I then drew in the UTM grid and added the reference numbers along the border. I also drew in my route, planned camp sites, and also added trail distances between key trail junctions, similar to what the Trails Illustrated maps do.
I still used TOPO North America to calculate trail distances, generate elevation profiles and route stats, and to save the route as GPX files for viewing in Google Earth.
My resulting map is 11x17, at 1:62,500 scale, containing all the detail from the 1:24,000 USGS maps. Some of the detail is a little hard to read, but fine using the magnifying "bubble" on my Suunto compass. They look good printed at the local FedEx/Kinko's. I'll print final copies on waterproof paper.
This was a very time consuming project. It took me hours to generate the map.
It is sad to see Nat Geo's DVD's get turned into "Software as a service" that requires a monthly fee. I don't feel alltrails.com is as good as the DVDs were.
