Spatial analysis in agriculture: an overview of precision agriculture [electronic resource].

Includes references.

Precision agriculture is a spatial information technology applied to agriculture. Also it is known as site-specific fanning that encompasses collecting and analyzing data for different locations within a field in a way that allows management decisions to vary in those diverse locations. Spatial information technologies include global positioning systems (GPS), geographical information systems (GIS), variable-rate technologies (VR1) and remote sensing (RS). Global positioning systems utilize a group of satellites used for accurately locating ground position. Geographical information systems encompass computer hardware and software with procedures for compiling, storing, retrieving, analyzing and displaying spatial data. They are designed to assist with planning and decision-making. Variable-rate technology is used for applying soil amendments at variable-rates within a field. Remote sensing involves the detection of energy reflected or emitted from an object with a sensor that is not in direct contact with the object. In sum, precision farming combines these technologies to help with decision making by providing information needed for crop and soil management in specific field locations.
