Cellphone photo GPS tagging

Posted by kucai on 1 January 2024 in English.

I have the suspicion that my phone is tagging the GPS location for some photos rather wrongly (timed offset is my guess). Found this out when comparing the locations against those indicated on JOSM photo overlay.

This despite the phone getting both L1 and L5 signals, and running with no sim card which should reduce cpu load further since there’s not much background processes that need to be handled.

To say I’m pissed is rather an understatement. Moving on, I will try leaving the phone to only record gps track and then matching photos from my cameras to that. No electronic shutter so extra wear and tear on that mechanical one! Shoulda bought that oly em10 back then.

GPS tagging on OSM?

In josm you can open photos with gps information. When you select and open a whole bunch of them (say after a road trip), they’ll show up on their own layer. Sometimes, some of the photos doesn’t really match with the location shown against aerial imagery in JOSM, especially those taken from inside a moving car. You can adjust the photo layer offset etc, but doesn’t really apply in my case since most of the other photos are accurately gps tagged.

So, it’s not really gps tagging on OSM like you asked, rather using gps tagged photos in an OSM editor to improve the map.
