    The NSW Government has acquired hyperspectral data to aid geological interpretation. The location of hyperspectral coverage is contained within this layer. The information contained in this publication is based on knowledge and understanding at time of writing (April 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 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.

    This layer shows the boundaries of ground gravity surveys acquired by the NSW government. Details on the spacing and age of the gravity station within each project area are in the attributes.

    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.

    The Field Observations (FieldObs) database stores observations and measurements of rocks collected by the Geological Survey of NSW. Includes location information, stratigraphic unit, links to mineral occurrence and drill hole data, photo and sketch captions, structural measurements and observations, lithology and rock descriptions, sample collection information, and petrophysical measurements (magnetic susceptibility, radioelement and density).

    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.

    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.
