2. Batch Global Watershed Delineation
This function allows delineating global watersheds for batch points located in Catalog Units. The
function performs first a local delineation in the point’s Catalog Unit. It then merges the resulting local
watershed with the Catalog Units polygons located upstream. The function also allows computing
global parameters by performing operations such as average, weighted average, sum (see list in online
help) or by using a custom operator (e.g. 10-85 slope computation). Parameters for global watersheds
may also be computed with the function Compute Global Parameters.
The preprocessing steps required by this function are described in the document Global Point
Delineation with EDNA Data and in the online help.
