NSW Geoscience Metadata
NSW Elevation Greyscale
Elevation is a greyscale layer with a histogram-equalised colour stretch. Cooler colours indicate lower values and warmer colours represent increasingly higher elevation. Elevation is derived from 5 metre LiDAR coverage of NSW and has been resampled to a uniform 25 metre grid cell size.

Resource lineage
- Statement
- Elevation (in metres above sea level) is derived from elevation data acquired during airborne magnetic and radiometric surveys. Elevation is calculated by subtracting the ground clearance from the GPS altitude. Numerous surveys have been flown over NSW. For each survey an elevation grid is generated and merged with to create a statewide DEM. In regions with gaps, shuttle radar (SRTM) has been used.
