SAGA algorithm provider¶

SAGA (System for Automated Geoscientific Analyses) is a free, hybrid, cross-platform GIS software. SAGA provides many geoscientific methods which are bundled in so-called module libraries.

Not

Please remember that Processing contains only the interface description, so you need to install SAGA by yourself and configure Processing properly.
