Adding geotag feature to record app #1966

Closed amelillo closed 5 months ago

amelillo commented 5 months ago

Description of the feature you're suggesting.

I was thinking about the recording app and the GPS capabilities of the HackRF. Wouldn't it be useful to be able to geotag a recording, right after having saved it to the sd card, to be able to reference it withouth the need to choose a proper filename? Then, we could even export the recordings and the geotag data to display recorded signals on a map. Especially useful when dumping subGHz signals of gates, remotes, doorbells and similar.

Anything else?

It is doable, will look into it. For now I think, adding it to the txt (lat=23.2422 lon=2.3444) format should be enough, and maybe a show on map if the geo info present.

Sure. The single recording should be referenced in the txt file (ex. RECORDING01.C16 LAT=XX.XXXX LON=XX.XXXX), one recording per line. Showing them on map might be a waste of programming time as it would be really useful only if the map could zoom at street level.

Map can't do (by default) the street level zoom, so showing signals in a map wouldn't be effective. My idea is when i got a recording01.c16, that has a recording01.txt too, and it a gps module is present, then it would store the coordinates too. Could check the location per recording on the map.

But an external app could load all recording txt-s, and parse them, and show them on a map. So it wouldn't grow the base apps too big, and won't confuse users (who don't have gps, why there is a gps list button).

Linked the displayer ext app, so if merged this will be closed. If want to request more features for this topic, please open a new issue.
