Hello, I am new to ENVI and have of course quite some questions while getting into the software. Out of curiosity if it works I tried to open a *.he5 file I retrieved from the OMI Aura datasets. When I try to open it as a generic external file than it is not shown in the open dialogue because the file extension does not fit. After switching to 'show all files' and choosing the dataset I want to open I get the ENVI error: File does not appear to be a valid HDF file. Can you tell me how to open one of those files? I know for sure that it is a HDF5 coded file and I wrote myself a Python script to convert the information held in the file into geo-objects in a ArcGIS file geodatabase. I read ENVI is able to read HDF5, so I'm a bit puzzled... Bests, Thomas
