For the Appalachian Trail:
http://postholer.com/gmap/gmap.php?trail=at

This map represents the entire Appalachian Trail in the greatest possible
detail. You won't find anything else like it on the web. It's the next best
thing to having Google Earth or mapping software installed on your computer.

It uses Google Maps, with Satellite, Topo and Hybrid maps available. And if
you're a Pacific Crest Trail fanatic, we've got the PCT as well:

These are currently in the testing stage and we hope to base some really
exciting new features on them.

Excellent! We're really at the stage where buying giudebooks is kind of obsolete.

That's pretty cool. I like the old mapquest with the topo on it. My computer got reconfigured this summer and whe I went back to mapquest I couldn't get the old topos. I found it on your site but I couldn't zoom in like before. I'll keep playing with it. Thanks.

Speed is still an issue, even over broadband.

The map definitely needs to be larger.

I would have thought that shelter locations and ideally water sources would be noted. There's a lot that could be done to move beyond a basic map of the trail corridor to complement with associated data useful to hikers.

Interesting note: The map shows the AT running 200 yards or more east of the parking lot at the end of the National Forest Service road leading up to Deep Gap, North Carolina, when in fact the AT runs through the parking lot. My guess is that there will be a lot of these minor inconsistencies between the trail route and actual maps.

Keep in mind this map is for testing purposes, so what you are seeing is absolute bare-bones. I'm trying to nail down the basic stability at the moment and it's been wildly successful so far, with a huge number of visitors.

Much, MUCH more will be done beyond the basic map and I'll leave it at that for the moment.

The end product will allow the viewer to resize the map to whatever they wish.

The speed issue is largely dependent on the Google, Terraservice, etc servers. I have no control over those and that's where the bulk of the content originates. You'll especially notice this slowness with the TOPO and Satellite maps. The trace data originates from postholer.com and the amount of data is insignificant compared to the map data.

Yes, you will find descrepancies, usually small ones, in the map and the actual trail. The data for the AT was collected in '02 I believe. So what may have changed since then? Or maybe the person(s) who collected the data deviated slightly? Yes, you can expect minor differences, such is the nature of collecting data with a GPS.

Anyways, I'm glad y'all like it! Hearing your kind words is a great pay-off for me.

Thank you!

So,... when you list Mountaineer Shelter, which wasn't on the trail in '02, nor (I believe) did the trail run that way in '02, ... do you not really show the new trail at all? I'm a little "lost," figuratively speaking. Not complaining, just asking so I'll know what's what.

I'd love to see the new reroute that takes the trail to the Mountaineer Shelter.

Thus is the downside of all maps. Maps are only as accurate as their data. If the most current data available is 5 years old, recent trail changes will surely be missing.

The upside to a web map is the data can be easily updated should it become available. :D

This is a test map. In the very near future you will be able to resize and do a WHOLE lot more. :D
