1. DSM Steps

2. DSM steps
• Step 1: Decide on mapping focus
– Study area
– Geographic projection
– Mapping soil property or class (categorical) values
• Step 2: Identify data needs and sources
– Data needs (SCORPAN factors)
– Data sources (Availability of SCORPAN factors)
• Step 3: Data collection and documentation
– Database creation
– Metadata development
• Step 4: Input data preparation
– GIS database development
– GIS operations (clipping, re-projection, format translation,)
– Digital terrain analysis (digital terrain parameters)
– Image/raster analysis (correction, re-sampling, normalization, PCA)
• Step 5: Spatial prediction
• Step 6: Accuracy assessment
