Note: Slides 17 through 21 describe the application of Spatial Analysis involving “spatial context” relationships as opposed to Spatial Statistics involving “numerical context” relationships most commonly used in Precision Agriculture (Surface Modeling to establish continuous spatial distributions of mapped data and Spatial Data Mining to investigate the relationships between dependent and independent map layers). The application of Spatial Analysis techniques is fueling Precision Conservation, an extension that focuses on modeling flows and cycles off agriculture fields.  For related discussion, see online papers at…
