Updates in ENVI 5.4.1

ADS80 images can be used with the ENVI Photogrammetry Module. ADS80 is the first airborne digital sensor supported in the Generate Point Clouds and DSM by Dense Image Matching tool.

The Generate Point Clouds and DSM by Dense Image Matching tool has a new Refine Point Clouds parameter. If set to Yes, the point clouds will have smoothed height values but will not contain any intensity or color information. The associated API routine, ENVIGeneratePointCloudsByDenseImageMatchingTask, similarly has a new REFINE_POINT_CLOUDS parameter.
