Metadata Portal Metadata InformationContent TitleNSW Elevation and Depth ThemeContent TypeHosted Feature LayerDescriptionElevation and Depth is the measurement of the Earth’s surface above or below a vertical datum to obtain the height of the land. Data is collected using a range of sensors including: laser, sonar, radar and optical.Technical methodologies are used to derive spot heights, raster surfaces, contours, 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 Clouds - The point cloud data set consists of point clouds captured from LiDAR (Light Detection and Ranging) and derived from airborne imagery using photogrammetric techniques. Spatial Services Point Cloud data is available for on demand download from Geoscience Australia ELVIS Platform. Digital Elevation Models - Digital Elevation Models (DEM) are derived from Spatial Services’ (SS) point cloud data. The DEM is a bare earth representation of the earth’s surface 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 is 5m resolution. Areas of no data caused by steep slopes, shadow and vegetation have been interpolated or filled-in with another data source and will not be as accurate as the bare open ground areas. The data is not hydrologically enforced (breaklines) or hydrologically conditioned (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 and Depth provides an accurate representation of the Earth’s surface enabling evidence-based decision making, 3D modelling, planning and earth 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 Date05/04/2020Data Currency01/01/3000Data

Export Data Access API NSW Positioning Theme Survey Mark GDA94 multiCRS MultiCRS service - supporting requests in multiple Coordinate Reference Systems - Information Sheet Note: GDA94 coordinates for NSW survey marks are no longer maintained. This data has been superseded by NSW Positioning Theme Survey Mark GDA2020 multiCRS or NSW Positioning Theme - Survey Mark GDA2020 A new series of ‘multiCRS’ web services have been published to support GDA2020. These new ‘multiCRS’ services: · have a spatial reference of GDA2020 · support alignment with GDA2020, GDA94 or [WGS 84-aligned-to-GDA2020] GIS environments,using built-in server-side transformations: o GDA94 < NTv2-CPD > GDA2020 o GDA94 < NTv2-CPD > WGS 84 aligned to GDA2020 o GDA2020 < NULL > WGS 84 aligned to GDA2020 Note: ESRI software will automatically align by transforming from the sourceSpatialReference (GDA94). Other software may need to set client-side transformations from the SpatialReference (GDA2020). Note: Client-side transformation(s) can be used to over-ride these default transformations.The original [WGS 84-aligned-to-GDA2020] is still available, without the ‘multiCRS’ suffix. In due course, and allowing time for user feedback and testing, it is intended that the original service name will adopt this new 'multiCRS' functionality.Please note that SCIMS Online is the official option for obtaining state control survey data for cadastral surveys as it offers legal traceability.

Metadata Portal Metadata Information Content TitleNSW Positioning Theme Survey Mark GDA94 multiCRSContent TypeHosted Feature LayerDescriptionThis service provides GDA94 coordinates, heights and related information for NSW survey marks that form the official State control survey network (as reported in SCIMS). This service controls the precision of numerical output in a manner that mirrors SCIMS Online available through the Spatial Services Portal.The web service provides a wealth of data on each mark, including:mark type (Permanent Mark, State Survey Mark, etc.) mark number horizontal coordinates and their accuracy (class and order) heights and their accuracy (class and order) status of the mark (destroyed, restricted access, etc.) The mark type is represented using various shapes and the accuracy of the mark (both vertical and horizontal) is communicated by the colour. This web service allows users to easily integrate survey control mark data from SCIMS into Open Geospatial Consortium (OGC) compliant spatial platforms and applications. Data provided by the NSW Survey Mark web service can be used in a variety of engineering and surveying applications, including but not limited to: cadastral survey planning flood studies and hydrographic modelling infrastructure developmentsite calibration at construction sites elevation modelling preservation of survey infrastructure.The NSW Survey Mark web service gives users an alternative method to access state control survey data that can be incorporated into their GIS package without needing to log into SCIMS Online.Please note that SCIMS Online is the official option for obtaining state control survey data for cadastral surveys as it offers legal traceability.
