I am in the process of developing a site for online waypoint storage and tracking;
Other then GPS point and maybe and icon, how much other information do you get stored. What I am thinking is being able to store date/time, temp, altitude, color, depth, detailed descriptions, images, previous sighting history, etc...
I could go on and on with what I would like to have on each point.
As for sharing, it would be a lot easier to get the data online then having to give someone a copy or even your SD card and hope they didn't "f" it up.

I'd like to know people opinions on this.
