About GeoSTAC
GeoSTAC currently contains 55 GB of data and three spatial analysis tools.
The GeoSTAC database and toolset will continue to grow, providing
agricultural and environmental GIS professionals with an unparalleled
system for consistent and efficient analyses to better understand the
agricultural landscape and the interaction of important environmental
variables.
How does GeoSTAC work?
GeoSTAC runs within the ESRI ArcGIS software platform (ESRI, Redlands, CA)
with the ESRI Spatial Analyst extension. GeoStac was designed to run on
ArcGIS version 9.1
GeoSTAC users will need a fully licensed installation of ESRI software
running on a computer with at least the minimum hardware requirements
specified by the current ESRI recommendations.
With GeoSTAC, users can perform geospatial analysis that involves:
- Crop production
- Soils characteristics
- Natural resources management
- Weather
- Land use/land cover
- Agrochemical use
- River and stream networks
- Watershed characteristics
A few examples of the types of environmental assessments that users can
perform with GeoSTAC include the following:
- Mapping almond growing counties in California
- Summarizing and mapping runoff potential for soils in Iowa by watershed
- Mapping soils erosion potential for corn growing soils in the Midwest
- Identifying the locations where a particular pesticide use coincides with
low pH soils
- Identifying watershed with the highest intensity of barley production in
the high plains region
- Determining average monthly rainfall during a May pesticide application
for counties with high soybean acreage
GeoSTAC currently contains 55 GB of data and three spatial
analysis tools. The GeoSTAC database and toolset will continue to grow,
providing the crop protection community with an unparalleled system for
consistent and efficient support of pesticide risk assessments.
For example...
...an analysis was performed in using GeoSTAC to identify the average
pH of the surface soil layer for counties where corn is grown. With
GeoSTAC this complex nation-wide analysis could take as little as 10
minutes.
