This is a web interface wrapped around a database that lets individuals enter information about who they heard during something like a simplex net. This is useful for determining where holes are in critical communication networks, and other connectivity information. (And, it generates pretty KML maps that are simply fun to play with).
The good news is that the new system allows multiple groups to all have their own area of the database to play with. The bad news is that there is no documentation yet (again, my finger injury hasn't fully recovered). But hopefully the system is somewhat intuitive.
It's fairly simple: you log in with your groups login, enter information about where you're at physically during an event and then click on check boxes for each person you hear and optionally fill in how good their signal was. After an "event" is over, you can download the results in a number of different formats including a simple connection "bubble diagram", a google earth/maps KML file, and a CSV export.
The system can be accessed from: http://simplexmap.hamtools.org/
If you want to:
Feel free to add callsigns of your affiliates, etc, to test out the system. Pretend in your mind that you were listening to a net and enter a few people and the signal strengths they may have had. Then, after you've finished, you can go into the "just download the results" screen and download the new connection maps based on your modified data.
