Welcome

terraGIS is a web-based Geographic information System (GIS) that allows cotton growers, farm managers, consultants, extension staff, researchers, state and federal government agency personnel and policy analysts access to digital biophysical data (e.g. soil, water and hydrological properties) collected and generated as part of a series of Cotton Research and Development Corporation projects entitled "Understanding the salinity threat in the irrigated cotton growing areas of Australia".

Biophysical data is available in seven irrigated cotton growing areas (i.e. Toobeah, Ashley, Wee Waa and Gunnedah, Trangie and Warren & Bourke) located in five catchments (Macintyre, Gwydir, Namoi, Macquarie & Darling).

The ancillary biophysical data sets available in terraGIS include;

• Cadastral (i.e. water storage reservoirs, irrigation fields, roads and water courses),
• Ancillary (i.e. EM38, EM34, gamma ray spectrometry, DEM - elevation),
• Soil properties (i.e. soil texture, exchangeable cations, CEC, pH, ECe, ESP, Ca/Mg)
• Water properties (i.e. permanent wilting point, field capacity, available water content), and
• Hydrological properties (i.e. deep drainage, hydraulic conductivity, groundwater recharge).

The ancillary data and biophysical information shown in terraGIS was collected using grants provided by;

• Cotton Research and Development Corporation,
• Australian Cotton Cooperative Research Centre,
• Department of Environment and Heritage,
• Department of Environment and Water
• Department of Agirculture, Fisheries and Forestry
• Salt Action.
