m3georeferencer

M3 Georeferencer is an interactive python GUI built for hand-georeferencing Moon Mineralogy Mapper images to a global LROC WAC basemap.

Installation

M3 Georeferencer can be directly installed from from the Python Package Index using pip.

pip install m3georeferencer

Usage

M3 Georeferencer can be most easily accessed directly from its command-line interface CLI. To see the help menu, use:

m3georeferencer.exe -h

If all default arguments are used, a file named "basemap.tif" must be in your current working directory. Otherwise, the main syntax is as follows.

m3georeferencer.exe [path to binary .IMG file] [path to ENVI .HDR header file]

This will open a file dialog window where you can select where to save the resulting Ground Control Points (GCPs). After this dialog, the following window will open: The following controls will allow you control the GUI:

• Middle Mouse Button: pan around image
• Scroll Wheel: Scroll in/out of image
• Left Click: Place GCP.
• Right arrow key: Advance GCP selection.

The sequence for saving one ground control point is as follows:

1. Advance GCP Selection
2. Place GCP in M3 Image
3. Advance GCP Selection
4. Place GCP in WAC Base map
5. Advance GCP

Repeat this sequence for ~50-80 Points to get a good georeference on each M3 image.
