The APRSWebService provides an XML interface to the VA7BCW-7 APRS interface. It can query last heard APRS packets by callsign or within a certain radius of a latitude/longitude pair.

Requires key: no

Parameters

callsign	callsign to query
since	within number of seconds ago
lat	latitude to query around
long	longitude to query around
radius	radius in kilometers to query around a lat/long

Application Notes

Presently VA7BCW-7 stores packets with coordinate data, and then only certain sub-types such as position reports. Weather reporting is not yet supported.
