<b>NEW</b>

We have released a new GDA2020 version of our Foundational Spatial Data Framework (FSDF) datasets which replaces the current GDA94 version. This updated service aligns our spatial data with the national standard, improving accuracy, consistency, and compatibility with modern positioning technologies.

 

The previous service will remain available during the transition period as GDA94 services are retired, but users are encouraged to move to the new GDA2020 service as soon as practical.

Content TitleRelative Height - NSW Elevation and Depth Theme - GDA2020 ServiceContent TypeHosted Feature LayerDescriptionRelative Height is a point feature class representing relative heights of a vertical face of a cliff.Elevation and Depth provides an authoritative digital representation of the Earth’s surface enabling evidence based decision making, policy development and an essential reference to other foundation datasets.Elevation and Depth underpins:<ul><li>Safe hydrographic, 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>Definition of maritime and administrative boundaries</li><li>Defence and national security</li><li>Natural resource exploration and exploitation</li></ul>Data is as initially captured at 1:25 000, 1:50 000 and 1:100 000 scales from stereoscopic aerial photography.Initial Publication Date03/02/2020Data Currency01/01/3000Data Update FrequencyOtherContent SourceData provider filesFile TypeESRI File Geodatabase (*.gdb)Attribution©

For current information go to <a href="https://www.spatial.nsw.gov.au/">spatial.nsw.gov.au</a>Data Theme, Classification or Relationship to other DatasetsNSW Elevation and Depth Theme of the Foundation Spatial Data Framework (FSDF)AccuracyThis 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 Accuracy Horizontal: +/-1.25 @95% Confidence IntervalSpatial Accuracy Vertical: +/-0.9 @95% Confidence IntervalCalibration certification (Manufacturer/Cert.
