Prepare the maps required by TRIP2 (:table align='left' width=100% cellpadding=5 cellspacing=0:) (:cell:)

• Flow direction map
• River sequence map
• Elevation map
• Extract a region of interest
• Mask the upstream region of one given point

(:cell:) Attach:mekonglp_30sec.gif Δ (:tableend:)

In case you are interested only in one part of the river and you want to economize calculating time, you can also make the maps which contain only the upstream regions of one given point.

The program: >TRIP2/map/calc_maskup.f will help you to do that.
