- 4. • Install plugin“QuickOSM” Download OSM

- 7. Input ground control point location( need at least 4 points and RMS error should be very less )
- 9. • Select shapefiletypes ( 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) andbuffer from fault line

- 14. • Calculates thehillshade 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. https://docs.qgis.org/3.4/en/docs/user_manual/processin g_algs/qgis/rasterterrainanalysis.html?fbclid=IwAR3AKzQv B1DVlkCmZ7rweXV1VePGV4m- OkflSWsWjf2S3i3nsevRogoando#slope 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 theaspect 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. https://docs.qgis.org/3.4/en/docs/user_manual/processing_algs/qgis/rasterterrainanalysis.html?fbclid=IwAR3AKzQvB1DVlkC mZ7rweXV1VePGV4m-OkflSWsWjf2S3i3nsevRogoando#slope Aspect
- 16. • Calculates theslope from an input raster layer. The slope is the angle of inclination of the terrain and is expressed in degrees. https://docs.qgis.org/3.4/en/docs/user_manual/processing_algs/qgis/rasterterrainanalysis.html?fbclid=IwAR3AKzQvB1DVlkC mZ7rweXV1VePGV4m-OkflSWsWjf2S3i3nsevRogoando#slope Slope
