Summary

Description

This data is a 3 second Digital Elevation Model (DEM) over the State of Queensland and includes a 100 km buffer into The Northern Territory, South Australia and New South Wales. This data is a subset of the national 3 second (~90m) Smoothed Digital Elevation Model (DEM-S) Version 1.0 which was derived from resampling the 1 second Shuttle Radar Topographic Mission (SRTM) derived Digital Elevation Model (DEM-S) Version 1.0 which is a 1 arc second (~30m) gridded smoothed version of the DEM (ANZCW0703013355). The DEM-S represents ground surface topography, excluding vegetation features, and has been smoothed to reduce noise and improve the representation of surface shape.
