SAGA

The SAGA (short form for System for Automated Geoscientific Automation) environment contains powerful tools, some of which have very specific applications; for example, geostatistical analyses and fire or erosion modeling. However, we will explore some of the SAGA tools that have broader applications and often dovetail nicely with tools from other providers. Similar to GRASS, integrating the SAGA algorithms within the processing toolbox provides access to powerful tools within a single interface.

To explore some of the SAGA algorithms available through the toolbox, we will work through a hypothetical situation and perform the analysis to evaluate the potential roosting habitat for the Northern Spotted Owl.

We are going to continue using data from the provided ZIP file, and we will need the following files:

• Elevation file (dems_10m.dem available in the GRASS data folder)

• Hillshade file (hillshade.tif created in the GRASS section)

• Boundary file (crlabndyp.shp)

• Surface water file (hydp.shp)

• Land...
