These days I am evaluating GPSTuner PocketPC application. It displays your position on a map based on GPS input (and of course it has many more features besides this). The maps are basically normal bitmaps with calibration info added in a separate file with an .gmi extension. The thing is that there aren’t many calibrated maps out there for GPSTuner. OTOH there are plenty of calibrated maps for OziExplorer, a similar application. On the bright side, the calibration file is easily converted from one to the another format. Thus I’ve created a simple conversion application that convert’s OziExplorer’s map to GPSTuner’s gmi format. I’ve tested it on OziExplorer’s 2.1 and 2.2 calibration format. You can find the converter application here.
