IMAGINE Auto DTM will be retired effective with the release of ERDAS IMAGINE 2022.
The ERDAS IMAGINE 2020 Update 2 (v16.6.2) installer includes IMAGINE DSM Extractor, a new product for extracting 3D points from overlapping imagery using Semi-Global Matching (SGM).
IMAGINE DSM Extractor is faster and produces better results than IMAGINE Auto DTM. It works with all imagery types, sensor models, and file formats that we support, and there are no longer limitations on file size.
All customers of IMAGINE Auto DTM under maintenance at the time ERDAS IMAGINE 2022 is released will be automatically transitioned to IMAGINE DSM Extractor.
