This data product is a DTM from stereo images acquired at approximately 6 meters/pixel resolution, which allows an output DTM resolution of 20 meters/pixel. The DTM was generated using the Ames Stereo Pipeline software (https://github.com/NeoGeographyToolkit/StereoPipeline)and using automated methods. This DTM was generated for general and public use, including scientific and engineering purposes. This DTM also serves as a foundation for ortho-projection.",
