Outputs (1)

Name	Description
output	The output of this workflow will report all of the following (if known) of the image: The format driver used to access the file. Raster size (in pixels and lines). The coordinate system for the file (in OGC WKT). The geotransform associated with the file (rotational coefficients are currently not reported). Corner coordinates in georeferenced, and if possible lat/long based on the full geotransform (but not GCPs). Ground control points. File wide (including subdatasets) metadata. Band data types. Band color interpretations. Band block size. Band descriptions. Band min/max values (internally known and possibly computed). Band checksum (if computation asked). Band NODATA value. Band overview resolutions available. Band unit type (i.e.. "meters" or "feet" for elevation bands). Band pseudo-color tables.
