TRIP2: Extract A Region Of Interest

Prepare the maps required by TRIP2

Use the script $TRIP2/map/ which uses the NCO commands to extract flow direction and elevation first; then use $TRIP2/map/calc_rivseq.f to calculate river sequence based on the extracted flow direction map.

Example: Extract the Indochina region from the 1.0 degree global maps
