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

An open source implementation of the 'STARS' toolbox (Peterson & Ver Hoef, 2014, <doi:10.18637/jss.v056.i02>) 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).

Functions in openSTARS

Name	Description
calc_edges	Calculate edges for SSN object.
calc_offset	Calculate offset
assign_binIDs	Recursive function to assign binary id to stream segments Should be run for all outlets in the network ( = most downstream segments) and fills the binID for all segments
calcCatchmArea_assignNetID	Calculate total catchment area of a stream segment and assign a network id.
calc_attributes_edges	Calculate attributes of the edges.
calc_attributes_sites_approx	Calculate attributes of the sites.
calc_catchment_attributes	calc_catchment_attributes Aggregate attributes for the total catchment of each stream segment.
calc_catchment_attributes_rec	calc_catchment_attributes_rec Aggregate attributes for the total catchment of each stream segment.
calc_attributes_sites_exact	Calculate attributes of the sites.
calc_binary	Calculate binary IDs for each stream network.
import_data	Import data into 'GRASS.'
openSTARS	openSTARS: An Open Source Implementation of the 'ArcGIS' Toolbox 'STARS'.
