RoiView was originaly designed to replace DGX/MDX software which require bureaucracy to obtain. This software was used in order to view ROI-PAC interferometry processing results but producing an image from file was not so strait forward. In time support was added for ERDAS ER Mapper header files and for user provided parameters with or without header files.
Current RoiView version (0.75) is available for download at
