The Geo Reference dialog box is used to edit georeference data. It is displayed by selecting "Model|Edit Geo Reference."
The georeference data is exported to a usgs.model.reference file each time a model is exported. Some of the information in the file can be determined automatically by ModelMuse. Other information must be specified by the user. The user is prompted for the required information when starting a new model but it can be changed later in this dialog box. Usgs.model.reference files are used to help document the location of the model in model archives created by the USGS. for more information about usgs.model.reference files and model archives, see https://water.usgs.gov/ogw/policy/gw-model/modelers-setup.html#setup-refe.
For hypothetical models, the projection should be listed as "NA."
