Alignment Files

Georeferencing by default is done using GPS or GCPs (if provided).

Starting from ODM 3.0.2 people can supply a reference alignment file to georeference the program outputs. The reconstruction will be initially performed using GPS/GCPs and will subsequently be aligned to the reference model via a linear scaling/rotation/shift operation.

If you supply a file called align.laz, align.las or align.tif (single band GeoTIFF DEM) then ODM will automatically detect it and attempt to align outputs to this reference model. If it has another name you can specify using --align <path>.

The alignment file must be created in the base of your project folder. The base folder is usually where you have stored your images.
