Glossary for Geospatial Science

edge conditions:  In agricultural row crop imagery, the biomass values for cells in the middle of a healthy row are high, while the thin plant fringes or bare soil between rows have low biomass values.  Low biomass values along the edges of healthy rows are normal and are no cause for concern.  But edges cannot be distinguished by value alone from the low biomass values of regions of insect or disease damage which must be identified and given special attention.
