Additional information on groundwater levels is included. The purpose of this survey was to provide an overview of the groundwater resources for planning and management 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 knownPositional accuracy of 500 metres from geological base information. 0not knownAquifer boundaries derived mainly from surface geology with minor modifications based on available widely spaced borehole data0The aquifer map boundaries were derived from 1:250,000 scale geological maps and modified using borehole data and regional geophysical surveys. The water level information was obtained from standing water level measurements taken over a wide range of times. The map unit boundaries polygon collected via geographic Information system (ArcGIS). Core water resources attributes attached to map units boundary with additional attributes unique to individual surveys. The ESRI Geodatabase, MapInfo Table and Google Earth KML derived using FME Workbench. The published map is derived from the ESRI Shape using Microstation Bentley MicroStation Design (V8) software. The core attributes information associated with the groundwater, surface water and water development dataset was derived from the original map's legend and annotations.
