The area was mapped at a scale of 1:25,000. The aim of the mapping was to improve upon the 1998 vegetation survey mapped at a scale of 1:100,000. 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. The information was compiled as part of: 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. Reports and maps can be viewed from the Mapping the Future webpage: https://denr.nt.gov.au/land-resource-management/development-opportunities - Development Potential of the Gunn Point Area (2020) - Biodiversity Assessment of the Gunn Point Area (2020) - Groundwater Resources of the Gunn Point Area (2020) - Marine and Coastal Biodiversity Assessment of the Gunn Point Area (2020) - Soil and Land Resources of the Gunn Point Area (2020) - Soil and Land Suitability Assessment for Irrigated Agriculture in the Gunn Point Area (2017) - Vegetation Communities of the Gunn Point Area (2020) Download the spatial data package (contains spatial data, maps and reports) via https://data.nt.gov.au/ You are licensed to use the DENR geospatial products on the terms and conditions set out in: Creative Commons Attribution 4.0 International Public License (CC BY 4.0) at: https://creativecommons.org/licenses/by/4.0/legalcode If you do not agree to the terms and conditions you must not use the geospatial products.

Polygon topology rules applied are; must not overlap, must not have gaps and each polygon has only one label.0not knownPolygon data: Map unit boundaries digitised on screen directly from digital rectified field maps. Level of accuracy depends on the number of control points on individual map sheets. Control points exclusively used Map Grid of Australia (MGA) grid lines. Depending on the nature of the landscape (the number of control points), positional accuracy may vary. Positional accuracy generally considered high to very high. Point data: Site point coordinates derived from a geographic positioning system with general accuracy of within 10-50m. 0not knownField data (site information) described and classified according to national standards at the time of capture. Attribute values are assigned to each polygon and described in the Data Dictionary below. 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. 3 additional attributes have been compiled by the department's biodiversity group to join to each Vegetation Community Map Unit to describe: Fauna Flag (identification of species); High Probability of Cycas armstrongii; Groundwater Dependent Ecosystem presence (seasonal or permanent).
