The GeoRefImg module contains several commands - as documented.

You can start them via the command line.

• Start it by typing the GEOREFIMG command.
• GeoRefImg prompts to select objects (existing images) and then perform the repositioning and scaling controlled by the World files (TFW, JGW, PGW, GFW, BPW, WLD...).
• World files are searched in the folders of the original raster file.
• Use full paths (REFPATHTYPE=2).
• The additional command WORLDOUT can create a new world file from an existing positioned image.
