Area of Science:

  • Agricultural Science
  • Geospatial Technology
  • Environmental Science

Background:

  • Precision farming seeks to optimize soil and input use on a site-specific basis.
  • Key research components include spatial data, variability characterization, and process simulation models.
  • Geographical Information Systems (GIS) are crucial for managing and analyzing spatial data.

Purpose of the Study:

  • To explore the integration of GIS and simulation models for precision farming.
  • To highlight the role of GIS in the engineering component of precision agriculture.
  • To propose GIS as a platform for developing decision support systems for farm-level applications.

Main Methods:

  • Utilizing Geographical Information Systems (GIS) for spatial data storage, analysis, and presentation.
  • Combining GIS with simulation models to characterize agricultural processes.
  • Integrating GIS with global positioning systems for farm vehicle navigation.

Main Results:

  • Commercial GIS systems currently support static one- or two-dimensional simulation models.
  • GIS provides a platform for storing base data, simple modeling, and result presentation.
  • GIS facilitates the development of user interfaces and navigation control for farm machinery.

Conclusions:

  • The combination of GIS and simulation models is highly relevant for precision farming.
  • GIS can support the engineering aspects of precision agriculture, translating research into operational systems.
  • GIS forms a basis for developing decision support systems for practical precision agriculture at the farm level.
