Template:Features from Raster: Difference between revisions

Revision as of 19:39, 11 May 2023

The Features from Raster tool derives features such as streams and roadway embankments from an elevation raster.

Input raster – Select the input elevation raster.
Feature type – Select the feature type to generate.
- "Stream" – This option generates stream lines given the threshold area for stream generation.
- "Ridge" – This option generates ridge lines for the inverted raster given the threshold area for ridge generation.
Threshold area – The threshold area to use for stream or ridge generation.
Pre-processing engine – Which pre-processing engine to use.
- "Whitebox rho8" – Computes flow directions and accumulations using the Rho8 algorithm.
- "Whitebox full workflow" – Computes flow directions and accumulations using the Whitebox tool full workflow algorithm that uses a standard D8 method for computing flow directions.

Output coverage – Defines the name of the tool-generated output coverage
Breached, Flow direction, and Flow accumulation rasters are also generated from this tool. The names of these are currently hardwired to the original raster names ending in _demfill, _flowdir, and _flowaccum respectively.
