> Metadata in images serves no other purpose than invading privacy. That's not true as a blanket statement. If it weren't for gps metadata, photogrammetry[1] would be very difficult. I am able to make my own "google earth" type maps with a much higher degree of detail because I can fly my drone 100 feet over the land and take thousands of gps-stamped pics vs outdated google maps satellite imagery and then get them all stitched together to make a large GeoTIFF. All the processing is done on my PC using opensource WebODM[2], which can then be imported into opensource QGIS where accurate elevation data can be added. It also creates textured 3d models of the land and buildings which can then be imported into opensource 3d apps like Blender. It's been a huge boost. I also like being able to show all of my various images on a map to see where they were taken.
