This content shows how to download OSM shapefile, use geo-reference tool, analyses terrain (slope, hill-shade, aspect), and terrain profile tool.

Data for this workshop

4. • Install plugin “QuickOSM”
Download OSM

6. Geo-referencer

7. Input ground
control point
location ( need
at least 4 points
and RMS error
should be very
less )

9. • Select shapefile types ( Point, line, polygon)
• You also can manage your field here or later
(depends on your objective)
Please create active fault in Ube city
Create Shapefile

10. create active
fault (line)
and buffer
from fault line

11. Batch Processing

13. Raster terrain analysis

14. • Calculates the hillshade raster layer given a Digital Terrain Model in input.
• The shading of the layer is calculated according to the sun position: you have the options to change both
the horizontal angle (azimuth) and the vertical angle (sun elevation) of the sun.

The hillshade layer contains values from 0 (complete shadow) to 255 (complete sun).
Hillshade is used usually to better understand the relief of the area.
Hillshade

15. • Calculates the aspect of the Digital Terrain Model in input. The final aspect raster layer
contains values from 0 to 360 that express the slope direction: starting from North (0°)
and continuing clockwise.

Aspect

16. • Calculates the slope from an input raster layer. The slope is the angle of inclination of
the terrain and is expressed in degrees.
