Thanks for the comments SierraNevada and John. As far as what other day hike trails I'm considering working on, I don't have any current plans -- mainly I'm working on long trails. I'm all ears if you have suggestions.
Hi Alice. In answer to your question about other hikes to consider for your application. I suggest checking out the "TTUSDHYMD Nominations Summary" link. It lists what several of the members feel are the best hikes in the USA.
I believe that GPS will continue to become ubiquitous, and that applications like yours will become much more commonplace. I'm not sure what the profile of your typical user is, or will be, but you should also consider more "routes" as time passes. I differentiate "routes" vs. "trails", as the routes are not as easily followed, and the opportunity for getting lost is higher. So you would do "trails" for the new/novice hiker, and "routes" for the more experienced hiker that might want the assistance with route finding. Much of the information you would need is already available. Many GPX routes to be found on the web, including pictures. Your application simply saves the user doing some of the research, and eliminates the need for them to download GPX routes, and load onto their mobile devices.
Regards,
John
