Well, not quite...  (BTW:  Xastir does the waypoint/anti-tracker
thing too):

Andrew was asking if anything converts back to NMEA so that mapping
programs can be tricked into thinking it's APRS data, not just
produce waypoints on the map like the other solutions above will all
do.

In order to do this properly, you'd either need to have a very slow
incoming data rate on APRS, or you'd have to select one
callsign-SSID from the incoming packets and produce either a GPGGA
or a GPRMC string (or both) from the data, then dump it to a serial
port or a simulated serial port.

It'd be relatively easy to do it with Perl and a /dev/pty port.
