A similar service with a\n‘multiCRS’ suffix is available which can support GDA2020, GDA94 and WGS 84 ≈\nGDA2020 environments.\nIn due course, and allowing time for user feedback and testing, it is intended\nthat the original service name will adopt the new multiCRS functionality.Metadata Portal Metadata InformationContent TitleNSW Elevation and Depth ThemeContent TypeHosted Feature LayerDescriptionElevation\n and Depth is the measurement of the Earth’s surface above or below a \nvertical datum to obtain the height of the land. Data is collected using\n a range of sensors including: laser, sonar, radar and optical.Technical\n methodologies are used to derive spot heights, raster surfaces, \ncontours, triangulated irregular networks and digital elevation models.Datasets that form the Elevation and Depth theme include: Historical Contours (2m Urban, 10m and 20m)Current 2m Contours (State wide)Spot HeightsRelative HeightsPoint cloud (LiDAR and Photogrammetrically derived) (available for download from Geoscience Australia ELVIS Platform)Digital Elevation Model (available for download from Geoscience    Australia ELVIS Platform) Elevation Data Sets available from additional services.ELVIS – Elevation and DepthPoint\n Clouds - The point cloud data set consists of point clouds captured \nfrom LiDAR (Light Detection and Ranging) and derived from airborne \nimagery using photogrammetric techniques. Spatial Services Point Cloud data is available for on demand download from Geoscience Australia ELVIS Platform. Digital Elevation Models - Digital\n Elevation Models (DEM) are derived from Spatial Services’ (SS) point \ncloud data. The DEM is a bare earth representation of the earth’s \nsurface where all the above ground feature has been removed.Spatial Services have a number of different Digital Elevation Models Digital Elevation Model derived from LiDAR - Are 1m or 2m resolution and is not hydrologically enforced(breaklines) or hydrologically conditioned (identification and analysis of sinks).Digital Elevation Model derived Photogrammetry - Data\n is 5m resolution. Areas of no data caused by steep slopes, shadow and \nvegetation have been interpolated or filled-in with another data source \nand will not be as accurate as the bare open ground areas. The data is \nnot hydrologically enforced (breaklines) or hydrologically conditioned \n(identification and analysis of sinks).Spatial Services Digital Elevation Model data is available for on demand download from. Geoscience Australia ELVIS Platform as 2km x 2km tiles. You can also access the 5 Metre Digital Elevation Model Service in the Collaboration Portal.Elevation\n and Depth provides an accurate representation of the Earth’s surface \nenabling evidence-based decision making, 3D modelling, planning and \nearth surface representation.Elevation and Depth underpins:Safe hydrographicAeronautical and road navigationClimate science, including climate change adaptationEmergency management and natural hazard risk assessmentEnvironmental, including water managementEngineering projects and infrastructure developmentDefinition of maritime and administrative boundariesNatural resource exploration.Update frequencies vary for each dataset. Individual current status can be found under each Spatial data profile. The objective is to maintain elevation datasets to meet the FDSI requirements of key data users.Current programs include:Aerial LiDAR capture program across NSW.DEM and Point Cloud generation from photogrammetric techniques.Longer term programs include:Update of contour data using updated DEM data generated from LiDAR and Photogrammetry.Hydrological enforcement using improved surface models.Initial Publication Date03/02/2020Data Currency01/01/3000Data Update FrequencyOtherContent SourceData provider filesFile TypeESRI File Geodatabase (*.gdb)Attribution©\n State of New South Wales (Spatial Services, a business unit of the \nDepartment of Customer Service NSW). For current information go to spatial.nsw.gov.auData Theme, Classification or Relationship to other DatasetsNSW Elevation and Depth Theme of the Foundation Spatial Data Framework (FSDF)AccuracyThis\n dataset was captured by utilising the best available source at a \nvariety of scales and accuracies, ranging from 1:500 to 1:250 000 \naccording to the National Mapping Council of Australia, Standards of Map\n Accuracy (1975). Therefore, the position of the feature instance will \nbe within 0.5mm at map scale for 90% of the well-defined points. That \nis, 1:500 = 0.25m, 1:2000 = 1m, 1:4000 = 2m, 1:25000 = 12.5m, 1:50000 = \n25m and 1:100000 = 50m. A program to upgrade the spatial location and \naccuracy of data is ongoing.  Spatial Reference System (dataset)GDA94Spatial Reference System (web service)EPSG:3857WGS84 Equivalent ToGDA94Spatial ExtentFull StateContent LineageFor additional information, please contact us via the Spatial Services Customer HubData ClassificationUnclassifiedData Access PolicyOpenData QualityFor additional information, please contact us via the Spatial Services Customer HubTerms and ConditionsCreative CommonsStandard and SpecificationAS/NZS ISO 19115 - ANZLIC Metadata Profile Version 1.1AS/NZS ISO 19131:2008 Geographic Information - Data product specificationsOGC compliant Web Map Services (WMS) and Web Feature Services (WFS)Metadata\n for the relevant Spatial Services datasets complies with AS/NZS ISO \n19115-2, ANZLIC Metadata Profile v1.1 and ISO 19139 Intergovernmental \nCommittee on Surveying and Mapping (ICSM): Guidelines for Digital \nElevation DataDCS Spatial Services: Elevation Data Products Specification and Description (LiDAR)DCS Spatial Services: Elevation Data Products Specification and Description (Airborne Photogrammetry)  Data CustodianDCS Spatial Services346 Panorama Ave Bathurst NSW 2795Point of ContactPlease contact us via the Spatial Services Customer HubData AggregatorDCS Spatial Services346 Panorama Ave Bathurst NSW 2795Data DistributorDCS Spatial Services346 Panorama Ave Bathurst NSW 2795Additional Supporting InformationData DictionariesTRIM Number
