WinOV2 runs the TomTom Navigator command line program DumpOV2 to extract the Points of Interest (POI) entries contained in an overlay file (.ov2) and writes them to an ASCII text file (.asc). An option to run MakeOV2 is also provided so that overlay files can be created from a text fie containing POI entries in either WGS84 longitude/latitude format or GB Ordnance Survey National Grid (OSGB36) format.
In version 2.02 of WinOV2 the GUI has been simplified and drag-and-drop support added. The TomTom utility MakeOV2 is run to create overlay files so that Type 1 records are output. The order of the POI in the ASCII file (.asc and .csv) is no longer preserved in the overlay file.
