Today I put together a quick ArcGIS Online tutorial on how to map GPS data and make an elevation profile web app. Feel to free to download and try it out, it is pretty simple and a good introduction into making web apps with no programming. If you are a developer, here is the code on GitHub.
This web app can be a very useful tool for planning your own hike, quickly reviewing field team data, and as a preventative search and rescue tool for letting the public see the elevation change on any given hike.
