that this principle gives more credible generalization results because order-
based stream selection can lead to removal of short riverheads and removal
of significant streams with low order.
Algorithm was tested for DEM production in 1:500 000 and 1:1 000 000
(from 1:100 000 and 1:200 000) and 1:10 000 000 (from 1:1 000 000)
scales. For every scale several source DEMs with morphologically differ-
ent terrains were selected to estimate algorithm's ability to preserve dis-
tinct morphological features such as slope profiles and structure lines
sharpness. Some results are presented in
Figures 7-9
