Now that I’ve found a source of georeferenced weather radar images, I thought the next useful bit of data would be a vector overlay of all the fault lines in the Bay Area. This should be simple, right? After surfing for a couple of hours, the closest I’ve found to usable GIS data is a Google Earth KML file of just the Hayward fault. After another hour of fiddling around with conversion utilities, I have managed to convert this KML file to a GPX file (an open XML standard for storing GPS waypoints, track logs, etc.) using Fish-Track’s KML to GPX converter, but since WinAPRS can’t read GPX files, I need to convert this data to something it can, such as raw NMEA sentences, which another conversion utility, gpsbabel, fails at.

It looks like I have another feature request for the WinAPRS authors…GPX support.
