Global data and Erosion Analysis
The aim of the assignment project was to understand how to use global data sets in order to create various maps like slope, elevation, soil texture, hydrological modelling and conduct erodibility analysis.

Elevation
Elevation
This the elevation map of Kerala along with hillshade effect to give the full effect. The map was created by downloading the SRTM DEM data from global website and carried out operations like merge clip and visualised using effective symbology.
Slope
Slope
The map was created using the slope tool on the elevation model
Hydrological modeling
Hydrological modeling
This map is developed making use of the SAGA-GIS tools which is also powerful open source GIS software tools.
Erodibility Analysis
Erodibility Analysis
The soil map is accessed from the Harmonized World Soil Database and the land cover from ESA Land Cover 300m product. Raster calculator was used to carry out the erodibility analysis.
