Precision Farming in General:

 

Geographical Information Systems ("GIS"):

GRASS is a raster-based GIS, vector GIS, image processing system, graphics production system, data management system, and spatial modeling system.

ArcExplorer software is a lightweight GIS data explorer developed by Environmental Systems Research Institute, Inc. ("ESRI")

Scripts and Extensions for ArcView, from GeoCommunity , GeoComm International Corporation.

FuzME  (Fuzzy k-Means with Extragrades), Useful for making within-field management zones.  Software from Australian Centre for Precision Agriculture, The University of Sydney.

VESPER (Variogram Estimation and Spatial Prediction with ERror), Useful for mapping soil properties and yield (properly).  Software from Australian Centre for Precision Agriculture, The University of Sydney.

The USDA Geospatial Data Gateway  The Geospatial Data Gateway or Geo-Data Gateway provides easy and consistent access to natural resource data.

Soil Survey Geographic Database (SSURGO) from the National Soil Survey Center which is part of the USDA- Natural Resources Conservation Service, National Soil Data Access Facility, USA.

Digital Soil Maps for the State of Iowa, USA from The Iowa Cooperative Soil Survey

Iowa Orthophoto & Digital Raster Graphic Web Server currently serving 1:100,000-scale USGS Digital Raster Graphics (DRGs) for the State, and Digital Orthophoto Quarter Quads (DOQQs) for five Iowa Counties, USA.

Digital Soil Surveys for the State of Missouri, USA from Missouri Spatial Data Information Service (MSDIS), The Center for Agricultural, Resource and Environmental Systems, College of Agriculture, Food and Natural Resources (CARES) at the University of Missouri - Columbia.

 

Global Positioning Systems ("GPS"):

 

Remote Sensing:

Soil Sampling and Mapping:

Avenue Scripts

CalcArea script  This script will add separate columns to the first table in the view, assuming the first theme is a polygon theme, with area (in acres), perimeter, x centroid, and y centroid information.  Software produced by the Precision Agriculture Laboratory Agricultural Engineering Department, Texas A&M University, College Station, TX 77843 USA

MergeArea script  This script is programmed to let the user input the smallest size management unit that he/she wishes to work with and the script will continue to merge all the small polygons with larger ones until there are no more polygons smaller than what the user specified.  Software produced by the Precision Agriculture Laboratory Agricultural Engineering Department, Texas A&M University, College Station, TX 77843 USA

 

Variable Rate Technology ("VRT"):

 

Yield Monitors and Maps:

Texas Agricultural Experiment Station (TAES) filter. Its intended use is to remove as many erroneous yield data points as possible without relying on assumptions about the accuracy of the GPS locations, the number of machines operating in the field or the patterns of harvest.  The program is written in Borland C++ 5.0 for the EasyWin format. EasyWin is a windows type DOS program.
