Task 5: Slope Analysis<br />
<br />
Open a new QGIS project and add the layer called elevation_UTM. This is<br />
a DEM of eThekwini.<br />
Change the CRS of both the layer and the project to Cape/UTM Zone 36S.<br />
<br />
<br />
<br />
<br />
<br />
<br />
<br />
<br />
<br />
<br />
Zoom to the layer extent.<br />
Open the Properties menu of the layer and change the Color Map to<br />
Psuedocolor. This is in the Style Tab of the Properties window.<br />
This now symbolises the layer to show the altitude differences.<br />
Open the Raster<br />
Based Terrain<br />
Analysis window.<br />
Select Slope as the<br />
Analysis<br />
Select<br />
elevation_UTM as<br />
the input layer.<br />
Give the output a<br />
name and make sure to save in the<br />
correct folder.<br />
Select GeoTIFF as the output<br />
format.<br />
Check Add Result to Project Box<br />
Display the resulting image as a Psuedocolor map.<br />
The resulting image is a raster layer showing<br />
the slopes of the image.<br />
