Marine protected areas are parts of the NSW marine estate managed to conserve marine biodiversity and support marine science, recreation and education. The NSW system of marine protected areas includes: marine parks – six multiple use marine parks cover around one third (approximately 345,000 hectares) of the NSW marine estate aquatic reserves – 12 aquatic reserves cover around 2,000 hectares of the NSW marine estate national parks and nature reserves – include around 20,000 hectares of estuarine and oceanic habitats.

Areas restricted from mining or exploration. Reserves emplaced by external agencies or authorities. If a lease application covers part or all of one of these areas, it must be referred to and approved by the agency which created the restriction.

Drillhole sample geochemistry that has been reported by title holders to the department as part of the mineral exploration reporting requirements. The data is provided annually in the form of exploration data files and stored with the relevant tenement report in DIGS. Data mining of digital exploration data files stored in DIGS is largely complete for the period 2001 to present. Data mining continues for DIGS reports earlier than 2001 using OCR (optical character recognition) software to convert raster data into digital files for loading. Validation of data is an ongoing process. Data available to the public and industry is restricted to DIGS open file reports.

An index of 1:250 000 map sheets and special geophysics surveys that covers NSW. The index shows maps where the total statewide geophysics package has been clipped and spectrally reinterpreted. Each map sheet suite of geophysical imagery contains up to 20 different layers including: greyscale Total Magnetic Intensity (TMI), pseudocolour TMI, greyscale 1st Vertical Derivative (1VD) of the TMI, greyscale 2nd Vertical Derivative (2VD) of the TMI, pseudocolour TMI Reduced To the Pole (RTP), greyscale 1VD TMI RTP, greyscale TMI RTP tilt filtered, pseudocolour TMI RTP draped over greyscale TMI RTP tilt filtered, pseudocolour Bouguer gravity, pseudocolour isostatic Bouguer gravity, greyscale isostatic Bouguer gravity tilt filtered, pseudocolour isostatic Bouguer gravity draped over greyscale isostatic Bouguer gravity tilt filtered, pseudocolour isostatic Bouguer gravity draped over greyscale TMI RTP tilt filtered, etc. The MinView layer provides a link to the DIGS catalogue entry which has a set JPEGs, TIFFs and ECWs for the area.

Spatial data set showing Mining Divisions within New South Wales. Each Mining Division has a Mining Registrar. A title is considered to be within the Mining Division in which the most northeasterly portion of the title lies.

The Geochemistry (Whole Rock) data set contains information about the chemistry of rocks sampled in New South Wales and held by the Geological Survey of NSW (GSNSW). The data has been captured from analyses conducted by the GSNSW and from other work including academic research & collaborative projects, mineral exploration reports and geoscientific publications. The database contains geochemical analyses on nearly 27,000 rock samples which have been collected from field work and drilling activities which date back to the nineteenth century. There are also a small number of assay & hydro-geochemical results. It is an important dataset as the whole rock analysis of rocks for major and trace elements allows classification of the lithology of a rock and provides insight into the conditions in which the rocks formed as well as their economic potential.

AEM data has been acquired by the NSW government through NSW Exploration, Discovery 2000 and New Frontiers Initiative funding. Contained within this vector file is the location of AEMsurveys and acquisition parameters. The information contained in this publication is based on knowledge and understanding at time of writing (February 2017). Because of advances in knowledge, users are reminded of the need to ensure that information upon which they rely is up to date. The information contained in this publication may not be or may no longer be aligned with government policy nor does the publication indicate or imply government policy.

Many airborne magnetic/radioelement surveys have been acquired by the NSW government through the NSW Exploration, Discovery 2000 and New Frontiers Initiative funding. Others have been acquired jointly with Geoscience Australia (formerly AGSO). Contained within this vector file are details on each of the surveys and some acquisition parameters, which will help locate survey data stored digitally. Not all of these surveys have both radioelement and magnetic data.Some project areas have grids that have been merged from private exploration company data (that are open file). These are attributed as "private" exploration company data in the shapefile. The information contained in this publication is based on knowledge and understanding at time of writing (December 2016). Because of advances in knowledge, users are reminded of the need to ensure that information upon which they rely is up to date.
