Features from Raster
The Features from Raster tool derives features such as streams and roadway embankments from an elevation raster.
Input Parameters
- 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.
- "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 Parameters
- 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 _breached, _flowdir, and _flowaccum respectively. An additional extension is added to the end of the raster name based on the pre-processing engine used.
