Delorme has a handheld mapping GPS now called the PN-20. It comes with TOPO 6.0 software. There are several data types compatible with the Earthmate GPS PN-20:
» Aerial Data Packet (ADP) data
» DOQQ (Aerial Imagery)
» 3DTQ (USGS Quads)
» Sat 10 data (Satellite Imagery)
» Topo USA data (Detailed street and topographic maps)
Street Atlas is supposed to work on it also at a future date.
