What is GIS ?

A Geographic Information System (GIS) displays spatially referenced (i.e., related to a specific geographic area) data in the form of maps. Multiple layers of data can be assembled to provide a collection of data on many different parameters for a location.

The Winegrowing Regions of Texas has assembled data layers on key viticultural characteristics of climate, topography, and soils for each of the eight AVA of Texas. This interactive GIS can be used to obtain an overview of viticultural characteristics within an AVA and to explore the data for any specific location within an AVA.
