<b>RETIRING</b>
This GD94 service is scheduled for retirement.


Please begin transitioning to the GDA2020 service and update any maps, applications, or workflows that currently reference this service.


You can access the GDA2020 Service here:

<i>Please Note</i><i>
WGS 84 service aligned to GDA94
This dataset has spatial reference [WGS 84 ≈ GDA94] which may result in
misalignments when viewed in GDA2020 environments. A similar service with a
‘multiCRS’ suffix is available which can support GDA2020, GDA94 and WGS 84 ≈
GDA2020 environments.
In due course, and allowing time for user feedback and testing, it is intended
that the original service name will adopt the new multiCRS functionality.</i>

Content TitleNSW Elevation and Depth ThemeContent TypeHosted Feature LayerDescription
Elevation
 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: <ul><li>Historical Contours (2m Urban, 10m and 20m)</li><li>Current 2m Contours (State wide)</li><li>Spot Heights</li><li>Relative Heights</li><li>Point cloud (LiDAR and Photogrammetrically derived) (available for download from Geoscience Australia ELVIS Platform)</li><li>Digital Elevation Model (available for download from Geoscience    Australia ELVIS Platform) </li></ul>
<b>Elevation Data Sets available from additional services.</b>
<a href="https://elevation.fsdf.org.au/"><b>ELVIS – Elevation and Depth</b></a>
Point
 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. <b>Digital Elevation Models - </b>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 
<b>Digital Elevation Model derived from LiDAR -</b> Are 1m or 2m resolution and is not hydrologically enforced
(breaklines) or hydrologically conditioned (identification and analysis of sinks).
<b>Digital Elevation Model derived Photogrammetry - </b>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. <a href="https://elevation.fsdf.org.au/">Geoscience Australia ELVIS Platform</a> as 2km x 2km tiles.

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

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:
<ul><li>Aerial LiDAR capture program across NSW.</li><li>DEM and Point Cloud generation from photogrammetric techniques.</li></ul>

Longer term programs include:
<ul><li>Update of contour data using updated DEM data generated from LiDAR and Photogrammetry.</li><li>Hydrological enforcement using improved surface models.</li></ul>

 dataset was captured by utilising the best available source at a 
variety of 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. A program to upgrade the spatial location and 
accuracy 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 <a href="https://customerhub.spatial.nsw.gov.au/servicedesk/customer/portals">Spatial Services Customer Hub</a>Data ClassificationUnclassifiedData Access PolicyOpenData QualityFor additional information, please contact us via the <a href="https://customerhub.spatial.nsw.gov.au/servicedesk/customer/portals">Spatial Services Customer Hub</a>Terms and ConditionsCreative CommonsStandard and Specification
