1. Install DSM software
• QGIS
• SAGA
• R
• Rstudio
• ILWIS
Create DSM workspace
 C:DSM - where we will work
 C:DSMInput - where to keep input data
 C:DSMOutput - where to keep output data

2. Familiarity with MS Office

3. Example: Soil profile data from ISRIC

4. Explore data and develop database
• Import maps in QGIS and explore
• Open MS Office data and explore
• Scan hard copy maps and explore
• Exploration
– Legend
– Contents (codes, classes, missing, range, etc.)
– Georeferencing (Projection, coordinates, tie-points)
– Documentation (report, methods, etc)
• Classify data quality

5. Building geo-database
• Geo-reference the images
• Digitize boundaries where possible
• Enter/convert the point-data into CSV
database
• Re-project the maps to common datum
– MODIS (in Sinusoidal-Sphere projection) : convert
+proj=sinu +lon_0=30 +x_0=0 +y_0=0 +a=6370997
+b=6371000 +units=m +no_defs
• Save all the project/database in one folder

6. Example geo-database
• Use tie-points to georeference the jpeg image
• Digitize and build geo-database where possible
(and clean using topology clean tool)
• Import other layers (environmental factors)
• Import MS Excel files into geo-database (use CSV)
and convert to shapefiles
• Document all the data in the database

7. Assignment: Building geo-database for
DSM application-STEP 1
• Use your own data
• Explore the data
• Follow the steps for building the geo-database
• Build the DSM geo-database
• Save the database (C:DSMInput)
• Remember to hand in your work by Next
