I've added basic GPS functionality to the RTLSDR Scanner.
The idea is if you've set up a GPS device it will record the location of each scan which you can then create a map of signal strengths to view in Google Earth, a GIS (Geographic information system) or an image viewer.
Once you have added a GPS (Edit->GPS Devices) and enabled GPS logging (Edit->Preferences), simply start a continuous scan as usual. As each sweep of the frequency range is performed your location is added to it. Currently the most up to date location is used before the sweep ends, because of this I recommend only using narrow frequency ranges for accuracy. You may also want to increase the number of scans that are retained (Edit->Preferences) so you have a large dataset to work with.
