Landsat 8 and DEM for land cover/land use : necessary ?
By Redoxi,
I've read in several papers that in order to do a better land cover / land use identification with Landsat images, it is better to project them on a DEM and ortorectificate then.

So my question is : do I need to do this step, or can I use Landsat image "as is" ?
Would the response be different for Landsat 5/7 and Landsat 8 ?
Thanks in advance.
