Adjust GPS Image Data
If GPS data is missing from the input images or if there's a need to override some of the images' GPS data, create a geolocation file (geo.txt) with a text editor of choice.
If your geolocation data is in latitude/longitude/height above the WGS84 ellipsoid, your geolocation file should look like:
EPSG:4326
IMG_0001.JPG longitude latitude altitude
IMG_0002.JPG longitude latitude altitude
...
You can use a GEO file by uploading it along with the images. See also GEO File Format
note
The file must be named geo.txt
