NSW Elevation and Depth Theme – Relative
Heights 

Please Note
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.

Department 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 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.
