= '''Hydrological & Terrain Analysis Tutorial Using WhiteboxTools''' = |
|||
== Introduction == |
|||
This tutorial demonstrates how to perform hydrological and terrain analysis within QGIS. The workflow begins with downloading a DEM dataset, installing WhiteboxTools, and configuring QGIS to recognize the WhiteboxTools functions. Subsequent steps includes DEM preprocessing, flow direction and flow accumulation modelling, deriving slope and the creation of a Topographic Wetness Index (TWI) map. |
|||
== Data & Software Requirements == |
|||
* 30 m DEM of the Kananaskis region |
|||
* QGIS |
|||
* WhiteboxTools Open Core |
