At over 2100 miles, the Appalachian Trail pretty much defines the word “epic.” The original thru-hiking trail, it attracts thousands of adventure seekers each year.

TopoFusion was approached to undertake the difficult task of profiling the entire AT. We didn’t have to hike the entire trail, but there was quite a bit of data processing and extension of the software. All fun stuff as long trails like this really capture our interest and imagination.

The result is above — the entire AT profiled to high detail. According to Climbing Analysis, there’s over 500,000 feet of climbing on the trail. Think about that number for a while. That’s a lot of vertical.

Anywho, the profiles can be seen in the latest and greatest hiker’s handbook to the trail, Appalachian Pages by David Miller. The profile lines are watermarked vertically behind the mileage cues and narrative, giving a very handy reference while out on the trail. Check it out.

We’ve made the AT GPS data available for download from TopoFusion. This includes GPX and KML files for both the entire trail and all the shelters. Head over to:

TopoFusion Pro version 3.20 was released today.

Two new map servers have been added to the available imagery in TopoFusion:

1 – Canadian Topo Maps

2 – TIGER street data for the United States

These two image types come from different map servers, separate from both Terraserver and OnEarth.  The future is looking bright for public domain, public access map servers!

We also put together a fun page showing the history of the TF splash screen:
