Landsat module and reference system

The new Landsat import module in TerrSet reads the accompanying MTL file to import and process the data from the USGS archive. We have found one case where the MTL has an error in its documentation that results in the incorrect documenting of the reference system in the imported .rdc file. 

This occurred importing a Landsat 1 MSS scene for southern Africa. The MTL had an error in the EPSG code resulting in the .rdc file to record UTM-35N instead of UTM-35S. This is easily corrected after importing by changing the reference system in Metadata in Terrset or using the Metaupdate module.

    The Landsat import module is very useful. Will incorporate Terrset some module for Sentinel import in the future?

    Would an MTL error such as this cause the Landsat import module to not identify the accompanying bands with the file? I have been moving through chapter 3 section 4 of the TerrSet tutorial and I am unable to import the Landsat file because the module will not recognize the corresponding bands for the image. I have made sure that the bands are in the IDRISI format and they are in the same directory in the working folder. I have also tried using other Landsat images to see if it was just a one time error with the same results.

    In the latest version of TerrSet, 18.31, the Landsat module has an error importing Level 2 data. If you are importing Collection 1 Level 2 data, you can use the GeoTiff import module instead. Since Level 2 data is already atmospherically corrected, The GeoTiff module will just import the data as reflectance data. If you want to use the Landsat module and do your own atmospheric correct, then you will need to download Level 1 data. 

    This error has been corrected and will be in a future release.

    The latest version of TerrSet, 18.31, now supports the Import of Sentinel 2 data in JP2K format. The module in TerrSet is called SENTINEL.
