For years I've been using TopoZone.com to map GPS coordinates. The site allowed me to plot a GPS coordinate on a topo map, as well as pull coordinates from topo maps. This site was perhaps the greatest asset for finding remote cliffs.
Sadly, TopoZone was acquired by Trails.com is now fee-based.
My question -- what are your favorite web sites for doing cool stuff with GPS coordinates?

It does suck, and I'm not going to pay $50 a year for it, I’ve tried the trial offer and was not impressed. For that much I can almost buy the full set of USGS topo maps on CD. Maps.google.com recently added a terrain option that includes topo mapping (albeit limited on landmarks as it does not seem to load any from the typical USGS maps, and is a bit more granular with the contours)
It was an interesting move for trails to pay money and buyout topozon.com as the direction in the industry is moving to open source mapping (as pushed by google and yahoo)

if you really get into the meat of the Google maps API, you can add raster data sources from many different places. USGS and ESRI serve a lot of this data, you just have to know where to look for it.
for example:
http://www.peakmapping.com/maps/topomap/googtopo.html
but alas, im out of practice.
anybody want a soda?

This web site:
http://www.gpsvisualizer.com/map?form=googleearth
will let you upload multiple coordinates files (like .gpx), or text enter coordinates and create a google earth .kmz file with your waypoints displayed on it. Then you can take that file and convert it to a topo overlay and view that in google earth.

i have a built in GPS, map and compass. i learned how to hunt fish and to navigate through the woods from my old man (who could teach Tom Brown how to track). funny thing someone accused me of placing a cairn on a non marked trail. i don't need no freaking cairns. guaranteed i would get out of woods before he would.

Well, I finally did a bit of work and created a mashup that combines Google Maps and Microsoft TerraServer.
http://www.AdirondackRock.com/map.htm
Other sites do this, but my mashup goes further by providing these capabilities:
* Browse a topo map (with zooming) to find a location.
* Determine the exact coordinate of a location. Both UTM and Lat/Lng supported.
* Type in a coordinate (from our book or from a field reading) and navigate to that location. Both UTM and Lat/Lng supported.
* Create a link to a specific map, for emailing to others.
* Have a couple of buttons to quickly navigate to popular areas.
It seems to do the trick.
