Project

SoLIM Solutions supports two types of soil mapping projects: rule-based project and sample-based project. Both of them are based on the idea that soil types and/or soil properties can be inferred from soil-related environmental conditions, so they both require a set of environmental layers (or covariates) (stored in a GIS Database) which depict the environmental conditions which are indicative of soil. The difference between rule-based and sample-based is that in rule-base project, users need to define a set of rules (Knowledge Base) to express the soil-environment relationship explicitly, while in sample-base project, users need only to provide field sample points (Field Samples) to express the soil-environment relationship implicitly. The sample points can be those collected from a well-designed sampling strategy or from ad-hoc activities (meaning not design at all).
