The primary purpose of the investigation was to map, describe and evaluate soil and landscapes to inform future development. Core landform and soil attributes attached to the land units are included with the spatial dataset. The area was mapped at a scale of 1:25,000. The acid soil component was sourced from existing information mapped at a scale of 1:50,000. The extent of the Gunn Point Area covers approximated 70,800 ha. and is defined by the Howard Water Allocation Planning Areas north of Gunn Point Road to the coastline. Vegetation attributes were not included in this dataset. Refer to the dataset Vegetation Communities in the Gunn Point Area. Metadata record: http://www.ntlis.nt.gov.au/metadata/export_data?type=html&metadata_id=8739BD7DA89BF802E050CD9B214469EB This information was compiled as part of the Mapping the Future Project - Gunn Point This project has identified land capability, water availability and biodiversity values to support land planning and inform development potential over the Gunn Point area.

Polygon topology rules applied are; must not overlap, must not have gaps and each polygon has only one label.0not knownVaries depending on source dataset.0not knownThe attribute information conforms to the Australian Soil and Land Survey Field Handbook at time of capture. Attributes assigned according to the dominant feature. For example, where ten sites have been grouped to describe a particular map unit and two different soils described from these sites then the dominant soil is chosen. The department has assigned a list of core attribute values, described in the Data Dictionary below, to each polygon. The attribute naming format uses 10 characters with no spaces to be suitable for an ESRI shape-file format. An alias attribute name is applied to an ESRI file geo-database format. LAND EVALUATION: See Chapter 6 in report (refer to Supplementary Information in this metadata record) - General Land Capabililty evaluates landscape characteristics that could influence the general use of the land. Descriptions for key characteristics considered important have been added to the land unit polygon, including slope, rock outcrop, soil depth, soil drainage and acid sulfate soils. - Land suitable for irrigated agriculture. A Land Suitability Class is assigned for a range of 9 irrigated crop groups based on land evaluation limitations. Class 1 is suitable land with negligible limitations through to class 5 which is unsuitable land with extreme limitations. 0Two existing land unit and soil surveys have been compiled to produce new consistent mapping over the Gunn Point area. Primary datasets appended to compile the new mapping include; - Fogarty, PJ, Lynch, B and Wood, B (1984). The Land Resources of the Elizabeth, Darwin and Blackmore Rivers. - Hill JV and Edmeades, BFJ (2008). Acid Sulfate Soils of the Darwin Region.
