Source images must be geotagged in order to be uploaded for processing in Skycatch. However, if your images are not geotagged but you have the telemetry logs, it is possible to merge this with the EXIF data to produce geotagged images.
There are several options for how to geotag your images which are available on the internet, one potential option using Mission Planner to inject geotags is available here.
