Layer 2: Biophysical characteristics
2.1. Soil type and composition
What kind of topsoil is present (e.g. clay or sand)? Ideally, the classification uses the International soil classification system, but data availability may vary. Shapefiles are the ideal format but may not always be available. In any case try to look for descriptive reports that describe the local soil characteristics. For those unfamiliar with soil types, the FAO Soils Portal is a fantastic reference to learn more.
