openSTARS (version 1.2.3)

An Open Source Implementation of the 'ArcGIS' Toolbox 'STARS'

Description

An open source implementation of the 'STARS' toolbox (Peterson & Ver Hoef, 2014, ) using 'R' and 'GRASS GIS'. It prepares the *.ssn object needed for the 'SSN' package. A Digital Elevation Model (DEM) is used to derive stream networks (in contrast to 'STARS' that can clean an existing stream network).
