Geopositioning of wav-files
Connecting an external GPS-mouse to a Bat Pi 2 and setting the GPS option active (see manual) Gps tracks could be performed. The Bat Pi 2 supports Navilock NL-602U gps mouse.
Software (see manual) can combine a tracking point wih the recorded wav-file.
There are different formats (klm, shp, gpx, etc.) to store the geoinformation.
GoogleEarth, ArcView and other programs can show the points of recordings in a map (see below). The description of GPS referencing is in the manual.
