I was about to suggest something like this! Mine is specific to hiking though, and in reverse of what you're proposing. I'll add my input here but let me know if this belongs in its own thread (I'm new here).

When you search "___ trail" or "___ trailhead", would it be possible to show a map of the trailhead (with it pinned) and maybe a map of the trail itself? fs.usda.gov always has lat/long for trailheads in the location section, usually on the lower right. Example: http://1.usa.gov/1DGrpK1

In my area (Portland, Oregon) there is a wiki field guide (barely wiki though, it's difficult to get editing access) that has a decently standardized format: http://www.portlandhikersfieldguide.org/

This is another great idea! This might be a separate instant answer than the climbing one we were discussing above, but it is relevant on this page since its close to the same idea. I think the first thing needed is to find a good source with an api. The more information from 1 source, the better. I checked out your first link, and there seemed to be a good api for all sorts or recreation at http://www.usda.gov/wps/portal/usda/usda... and it seems fairly extensive. Though it should be looked into a little more.

Is there a JSON api somewhere that has this data?

If there isn't an api this could still work as a longtail instant answer. Basically crawl the site and build a list of trail heads and their coordinates. I don't think anyone has ever tried showing a map from a longtail but I think it could work and I'm happy to help out if you or anyone else want to try it.

The only api I can find for the USDA and other Federal Recreation sites is at https://ridb.recreation.gov/. The only site I have found that gives the maps and trailhead locations is the USDA, and that api only lists locations not trails. Would each destination be crawled for trail heads and coordinates?

I've looked up a few more sources for trails and hiking and I have found http://www.trailapi.com/ so far. I seems like it might be a good source and was on programmable web.

I did this search: http://screencast.com/t/MJMDfTPRX

And came up with a list of almost 2000 trailheads: http://screencast.com/t/dqqYxQ4jHg5u

Not sure if that helps at all - still learning about APIs and how they work!

That looks great! I posted a wall of text to Brendan's post. All of my ideas for the climbing data instant answers would apply to the hiking IA too since it's the same type of data.
