MultiCRS service - supporting requests in multiple Coordinate Reference Systems -\u00a0Information Sheet

A new series of \u2018multiCRS\u2019 web services have been published to support GDA2020. \u00a0These new \u2018multiCRS\u2019 services:

using built-in server-side transformations:

o\u00a0\u00a0\u00a0\u00a0GDA94 < NTv2-CPD > GDA2020

o\u00a0\u00a0\u00a0\u00a0GDA94 < NTv2-CPD > WGS 84 aligned to GDA2020

o\u00a0\u00a0\u00a0\u00a0GDA2020 < NULL > WGS 84 aligned to GDA2020

\u00a0 \u00a0 \u00a0Note: ESRI software will automatically align by transforming from the\u00a0sourceSpatialReference\u00a0(GDA94).
\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0Other software may need to set client-side transformations from the\u00a0SpatialReference\u00a0(GDA2020).

\u00a0 \u00a0 \u00a0Note:\u00a0Client-side transformation(s) can be used to over-ride these default transformations.

The original [WGS 84-aligned-to-GDA2020] is still available, without the \u2018multiCRS\u2019 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.


Metadata\u00a0Portal Metadata Information
Content TitleNSW Elevation and Depth Theme multiCRS
Content TypeHosted Feature Layer
Description

Elevation and Depth is the measurement of the Earth\u2019s 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:\u00a0

  • Historical Contours (2m Urban, 10m and 20m)
  • Current 2m Contours (State wide)
  • Spot Heights
  • Relative Heights
  • Point cloud (LiDAR and Photogrammetrically derived)\u00a0(available for download from Geoscience Australia ELVIS Platform)
  • Digital Elevation Model\u00a0(available for download from Geoscience \u00a0\u00a0\u00a0Australia ELVIS Platform)\u00a0

Elevation\u00a0Data Sets available from additional services.

ELVIS \u2013 Elevation and Depth

Point Clouds\u00a0-\u00a0The point cloud data set consists of point clouds captured from LiDAR (Light Detection and Ranging) and derived from airborne imagery using photogrammetric techniques.\u00a0

Spatial\u00a0Services\u00a0Point Cloud data is available for on demand download from Geoscience Australia ELVIS Platform.\u00a0

Digital Elevation Models\u00a0-\u00a0Digital Elevation Models (DEM) are derived from Spatial\u00a0Services\u2019 (SS) point cloud data. The DEM is a bare earth\u00a0representation of the earth\u2019s surface where all the above\u00a0ground feature has been removed.

Spatial Services have a number of different Digital Elevation Models\u00a0

Digital Elevation Model derived from LiDAR -\u00a0Are 1m or 2m resolution and is not hydrologically enforced

(breaklines) or hydrologically conditioned (identification and\u00a0analysis of sinks).


Digital Elevation Model Derived Photogrammetry -\u00a0Data 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\u00a0enforced (breaklines) or hydrologically conditioned (identification and analysis of sinks).

Spatial\u00a0Services\u00a0Digital Elevation Model data is available for on demand download from. Geoscience Australia ELVIS Platform as 2km x 2km tiles.\u00a0

You can also access the\u00a05 Metre Digital Elevation Model Service\u00a0in the Collaboration Portal.


Elevation and Depth provides an accurate representation of the Earth\u2019s surface enabling evidence-based decision making, 3D modelling, planning and earth surface representation.

Elevation and Depth underpins:

  • Safe hydrographic
  • Aeronautical and road navigation
  • Climate science, including climate change adaptation
  • Emergency management and natural hazard risk assessment
  • Environmental, including water management
  • Engineering projects and infrastructure development
  • Definition of maritime and administrative boundaries
  • Natural resource exploration.


Update frequencies vary for each dataset. Individual current status can be found under each Spatial data profile.\u00a0

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.

Data Theme, Classification or Relationship to other DatasetsElevation and Depth Theme of the Foundation Spatial Data Framework (FSDF)
AccuracyThe dataset maintains a positional relationship to, and alignment with, the drainage and topographic digital datasets. These datasets were captured primarily by digitising from the best available aerial photography at scales and accuracies ranging from 1:500 to 1:250 000 according to the National Mapping Council of Australia, Standards of Map Accuracy (1975). Therefore, the position of the feature instance will be within 0.5mm at map scale for 90% of the well-defined points. That is, 1:500 = 0.25m, 1:2000 = 1m, 1:4000 = 2m, 1:25000 = 12.5m, 1:50000 = 25m and 1:100000 = 50m.\u00a0A program to upgrade the spatial location and accuracy of data is ongoing.
