Generating GPX by hand and Geocoding pictures with GPicSync on Linux

Generating GPX by hand and Geocoding pictures with GPicSync

This reminder applies if you have pictures that need geocoding (e.g. to be uploaded on Mapillary) but you have no GPX file. We assume you have captured pictures alonside a path from a start point to an en point and that you are able to redraw this path precisely on a map. The first step will be to generate manually a GPX file, then to synchronize it with your pictures thanks to timestamps, and then GPicSync will geocode.

  1. Download GPicSync, install dependencies and make sure you can run the GUI with Python 2, e.g. python2 gpicsync-GUI.py
  2. Draw you actual path on https://geojson.net/ with these recommandations:
  • Place points at every key location, e.g. when you turned or passed in front of a remarkable location that is easy to distinguish visually on pictures (building, square, monuments...)
  • Find a good compromise between numerous points (= very accurate pat

  2. In left section, Select the project (AF), select Build settings, then All and Combined
  3. In Signing section select iOS Developer for all entries within Code Signing identity
  4. In left section, Select the target (AF), select Build settings, then All and Combined
