Field Mapping with GPS and GIS
GPS technology is used to locate and map regions of fields such as high weed, disease and pest infestations. Rocks, potholes, power lines, tree rows, broken drain tile, poorly drained regions and other landmarks can also be recorded for future reference.
GPS is used to locate and map soil-sampling locations allowing growers to develop contour maps showing fertility variations throughout fields. The various datasets are added as map layers in geographic information system (GIS) computer programs.
GIS programs are used to analyze and correlate information between GIS layers.
