How Do I Upload Ground Control Points?
If you used custom ground control points you will need to provide their coordinates. When uploading photos, you will be prompted to upload a CSV file with these coordinates. The CSV file is a comma-separated list of coordinates, and needs to contain the following columns:
- Coordinate ID
You will be asked to enter the coordinate reference system, and you must also know whether your units are in meters, US international feet, or US survey feet.
Please note: you will need to remove all spaces from the values.
I still can't do it!
