The OzEstuaries online GIS contains data for Australian estuaries (coastal waterways) and for oceans in the Australian region. Estuaries data include geomorphic habitat mapping, estuary condition, colour composite images (Landsat, MODIS and Quickbird satellite imagery and aerial photography), benthic classifications (from Landsat satellite imagery), bathymetry and population centres. Oceanic data include dissolved organic matter, chlorophyll concentration, suspended solids concentration and sea surface temperature (using MODIS satellite imagery) and bathymetry.

The GIS provides facilities to search for and zoom to estuaries, integrate mapping and imagery datasets, and retrieve statistical information from the OzEstuaries database; allowing users to view spatial and statistical information. The oceanic imagery provides a regional context for coastal waterways.

The GIS is part of Geoscience Australia's contribution to the Cooperative Research Centre for Coastal Zone, Estuary and Waterway Management (Coastal CRC). The geomorphic habitat mapping was conducted by Geoscience Australia for the National Land and Water Resources Audit, and is also part of Geoscience Australia's contribution to the Coastal CRC.

The Northern Australian Project online GIS, which has been chiefly designed to highlight the results of geochronological research within the project area, was first published in 2003 and updated in July 2004. GIS data reference layers include 1: 250,000, 1: 1 million, and 1: 2,500,000 geological data, regional geophysical images and a topographic map image. The geochronology and fluid inclusion points have been linked live to Geoscience Australia's OZROCKS, OZCHRON and PETROG Oracle databases. Forms display data to the user from these databases using customised query statements. Queries directed to geological layers display information derived from static ArcInfo shapefiles. The North Australia Project geochronology research has chiefly targeted the Arunta Block, Davenport Geosyncline, and the Granites-Tanami Block provinces within the project area.

The Yilgarn online GIS displays a wide range of data including geological datasets, topographical data, geophysical images and seismic traverses, whole rock geochemistry and geochronology samples. It provides an aeromagnetic interpretation (lithology distribution and structure) and a geological interpretation of the Archaean Yilgarn Craton, one of Australia's key mineral provinces. The online GIS also focuses on the Leonora-Neale Transect, by providing a detailed solid geology interpretation of the section. The Yilgarn Craton occurs within Western Australia and covers 10% of the Australian continent. Exposure of bedrock is extremely poor throughout the region and most known mineral deposits occur within or adjacent to sparse outcrop. The online GIS provides a view through the poorly magnetised cover to display bedrock distribution. Interpreted rock types of the region include granite, granitic gneiss, layered intrusions and sills. Interpreted structural elements include lithological banding, faults, and dyke swarms. Also presented are several surrounding and partially overlying Proterozoic and Phanerozoic basins and provinces.The Yilgarn Craton is arguably Australia's premier mineral province, attracting more than half the mineral exploration expenditure, and producing two thirds of the gold and most of the nickel mined in the country. For this reason, the online GIS provides the ability to display all deposits in the region or the option of displaying gold or nickel deposits only. Distribution of mineral deposits can be compared to other data layers including geology, and aeromagnetic domains.This map has been produced as a GeoPDF, which is an extension to the standard PDF file format viewed using Adobe Acrobat Reader. Layers can be turned off and on to customise the view of the data, similar to using Geographic Information System tools. In addition, GeoPDF maps are georeferenced to be compatible with other coordinated geographic data. Coordinate locations and distances can be retrieved automatically.A plug-in to view GeoPDF using Adobe Acrobat Reader is available as a free download ( http://terragotech.com/solutions/map2pdf_reader.php ).

Parcels delineate the approximate boundaries of property ownership as described in Napa County deeds, filed maps, and other source documents. GIS parcel boundaries are maintained by the Information Technology Services GIS team. Assessor Parcel Maps are created and maintained by the Assessor Division Mapping Section. Each parcel has an Assessor Parcel Number (APN) that is its unique identifier. The APN is the link to various Napa County databases containing information such as owner name, situs address, property value, land use, zoning, flood data, and other related information. Data for this map service is sourced from the Napa County Parcels dataset which is updated nightly with any recent changes made by the mapping team. There may at times be a delay between when a document is recorded and when the new parcel boundary configuration and corresponding information is available in the online GIS parcel viewer.From 1850 to early 1900s assessor staff wrote the name of the property owner and the property value on map pages. They began using larger maps, called “tank maps” because of the large steel cabinet they were kept in, organized by school district (before unification) on which names and values were written. In the 1920s, the assessor kept large books of maps by road district on which names were written. In the 1950s, most county assessors contracted with the State Board of Equalization for board staff to draw standardized 11x17 inch maps following the provisions of Assessor Handbook 215. Maps were originally drawn on linen. By the 1980’s Assessor maps were being drawn on mylar rather than linen. In the early 1990s Napa County transitioned from drawing on mylar to creating maps in AutoCAD. When GIS arrived in Napa County in the mid-1990s, the AutoCAD images were copied over into the GIS parcel layer. Sidwell, an independent consultant, was then contracted by the Assessor’s Office to convert these APN files into the current seamless ArcGIS parcel fabric for the entire County. Beginning with the 2024-2025 assessment roll, the maps are being drawn directly in the parcel fabric layer.Parcels in the GIS parcel fabric are drawn according to the legal description using coordinate geometry (COGO) drawing tools and various reference data such as Public Lands Survey section boundaries and road centerlines. The legal descriptions are not defined by the GIS parcel fabric. Any changes made in the GIS parcel fabric via official records, filed maps, and other source documents are uploaded overnight. There is always at least a 6-month delay between when a document is recorded and when the new parcel configuration and corresponding information is available in the online parcel viewer for search or download.Parcel boundary accuracy can vary significantly, with errors ranging from a few feet to several hundred feet. These distortions are caused by several factors such as: the map projection - the error derived when a spherical coordinate system model is projected into a planar coordinate system using the local projected coordinate system; and the ground to grid conversion - the distortion between ground survey measurements and the virtual grid measurements. The aim of the parcel fabric is to construct a visual interpretation that is adequate for basic geographic understanding. This digital data is intended for illustration and demonstration purposes only and is not considered a legal resource, nor legally authoritative.

This GIS web browser contains stratigraphic information from the southern flank of the Murphy Inlier, Lawn Hill Platform and Leichhardt River Fault Trough in the Western Succession of the Mount Isa Block. The principal lithostratigraphic units covered by this dataset include the Surprise Creek Formation, Mount Isa and McNamara Groups. The images are pixilated versions of those contained on CD Records AGSO Record 1999/10, AGSO Record 1999/15, GA Record 2002/3. The data contained on the CD's is more comprehensive, at a better resolution and also contains cross sections that are not available over the web. No drill hole data is supplied in this viewer. The data compiled for this viewer was collected during the course of the NABRE, AMIRA P552 and pmd*CRC projects. The respective CD's also provide measured sections at different scales with slightly varying information available at 1:400, 1:1000, 1:2500 and 1:5000 scales. The information at each scale is slightly different. Plot files ready for printing also accompany the measured sections. Each of the measured sections contains primary observational data (grainsize, lithology, bed thickness, sedimentary structure and gamma ray curve) map-based lithostratigraphic units as shown on the 1:100,000 geological sheets, interpreted facies and sequence stratigraphic surfaces. Sections were measured using a Jacobs Staff and Abney Level and the rocks were marked in 1.5 m intervals of true thickness. Gamma ray data was collected at either 50 cm or 75 cm intervals of true thickness using hand-held Scintrex GRS 500 spectrometers that measured total gamma ray counts. A beryllium standard was used to calibrate each spectrometer. Each machine was calibrated at intervals of two to three hours. Each gamma reading was averaged over an interval of ten seconds. Outcrop discontinuities prevented the collection of stratigraphic data in a line of continuous section. As a result most of the sections present in this data set comprise a series of segments combined to form a single composite section. The single sections were all measured within a radius of several kilometres of each other. Individual sections were spliced together at prominent marker beds (outcrop tracing of strata), or by the use of overlapping gamma ray curves in conjunction with facies descriptions. Section locations shown in the web browser depict the base of each composite section. Grid coordinates for the base each composite section can be found in the header block of the appropriate section. The geological maps used in this web browser depict the approximate position of supersequence boundaries. Not all the geology for the region has been included and only the geology relevant to the measured sections has been used. The supersequences provided are based on the most appropriate lithostratigraphic boundaries and no new geological polygons have been created. It should be noted that the Torpedo Creek and Warrina Park Quartzites have been placed in the Prize Supersequence. However, we acknowledge that due to mis-mapping of these sand bodies the Torpedo Creek and Warrina Park Quartzites from the basal part of the Gun Supersequence at some locations.
