Hi,
I was trying to clarify to myself the picture on possible issues in
using data concerning the present situation for analysis of situations
concerning the distant past.
I.e., if I want to perform visibility analysis or drainage analysis with
a DEM, concerning archaeological studies related to 5000 years ago,
should I introduce corrections reflecting erosion/deposition processes
or similar things, or is the effect of the related processes neglectable
over such a time frame ?
TIA for any feedback,
