This spatial data set is a compilation of 10 existing land resource surveys that were reinterpreted to identify land suitable for annual and perennial horticultural potential and soil drainage classes. This compilation data set is relevant at a scale of 1:50,000. The study area in the Greater Darwin region covers more than 9,700 km2. Information about the existing surveys is available in the associated metadata and technical reports. See list of surveys under Supplementary Information below. This project was initiated by staff from Dept Lands Planning Environment and Dept Land Resource Management. Additionally, staff from Dept Primary Industry and Fisheries supplied a set of conditions to identify the extent of soil-landscapes generally suitable for annual and perennial horticulture. (see Data Dictionary below) The land suitability mapping does not take into account the availability of groundwater. Groundwater information needs to be intersected with the land suitability mapping for a realistic assessment, unless surface water supplies can be utilised.
