Please, I processed MODIS image using Seadas (level 1B to L2_LAC 250meters). Now I would like to open this file in the Envi enviroment. I alread saw that envi can open
HDF files, but with this option I don't have the geophysical values automaticaly (I guess that I have to apply the slop and interception, but I can't see it).
Is there some way that make possible open L2_LAC files using Envi? Or some IDL code which convert L2_LAC to Envi format?
In your HDF files, slope and intercept are attributes of individual SDSs containing data products. You can view the header of an HDF file with its SDSs and SDS attributes using an ncdump function: 'ncdump -h hdf_filename'. You can find the ncdump command in your seadas directory seadas/hdf/HDF4/bin/. Once you know the right slope and intercept for each product, Envi should allow you to perform basic mathematical operations on a data block.
Let me know what works, good luck,
