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…
