The scenProc IMPORTGDAL step to import imagery data assumes that the imagery you use is georeferenced in some way. So for example as GeoTIFF or as BMP file with an accompanying world file. But that is not always the case of course. Some developers use unreferenced images and provide the needed coordinates in the INF file for resample.
Therefore I have now added a new step to scenProc that will read these INF files: IMPORTINF. This will go over the INF file and for each image defined in there add it as a feature to scenProc with the correct georeferencing. Afterwards you can use the image in the DETECTFEATURES step for example.
