NSW Elevation and Depth Theme - Relative Height

Export Data Access APINSW Elevation and Depth Theme – Relative\nHeight\n\n\n\nPlease Note\nWGS 84 service aligned to GDA94\nThis dataset has spatial reference [WGS 84 ≈ GDA94] which may result in\nmisalignments when viewed in GDA2020 environments. A similar service with a\n‘multiCRS’ suffix is available which can support GDA2020, GDA94 and WGS 84 ≈\nGDA2020 environments.\nIn due course, and allowing time for user feedback and testing, it is intended\nthat the original service name will adopt the new multiCRS functionality.Metadata Portal Metadata InformationContent TitleNSW Elevation and Depth Theme - Relative HeightContent 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:Safe hydrographic, aeronautical and road navigationClimate science, including climate change adaptationEmergency management and natural hazard risk assessmentEnvironmental, including water managementDefinition of maritime and administrative boundariesDefence and national securityNatural resource exploration and exploitationData 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©\n State of New South Wales (Spatial Services, a business unit of the \nDepartment of Customer Service NSW).

That is, 1:500 = 0.25m, \n1:2000 = 1m, 1:4000 = 2m, 1:25000 = 12.5m, 1:50000 = 25m and 1:100000 = \n50m. A program to upgrade the spatial location and accuracy of data is \nongoing.  Spatial Accuracy Horizontal: +/-1.25 @95% Confidence IntervalSpatial Accuracy Vertical: +/-0.9 @95% Confidence IntervalCalibration certification (Manufacturer/Cert.
