The properties altitude and azimuth together indicate the sun's relative position that will be used for creating any 3D model (hillshade or shaded relief). The following image displays an elevation model using the default hillshade symbology.Įxample hillshaded image. The inputs for this function are the following:īy default, a grayscale color ramp is used to display a hillshaded elevation model. This function uses the altitude and azimuth properties to specify the sun's position. The 3 second DEM was produced for use by government and the public under Creative Commons attribution.A hillshade is a grayscale 3D representation of the surface, with the sun's relative position taken into account for shading the image.

A full description of the methods is in progress (Read et al., in prep Gallant et al., in prep). The removal of vegetation effects has produced satisfactory results over most of the continent and areas with defects are identified in the quality assessment layers distributed with the data and described in the User Guide (Geoscience Australia and CSIRO Land & Water, 2010). Man-made structures such as urban areas and power line towers have not been treated.

The 1 second product provides substantial improvements in the quality and consistency of the data relative to the original SRTM data, but is not free from artefacts.

The dataset was derived from the 1 second Digital Surface Model (DSM ANZCW0703013336) by automatically removing vegetation offsets identified using several vegetation maps and directly from the DSM. The DEM represents ground surface topography, and excludes vegetation features. The 3 second (~90m) Shuttle Radar Topographic Mission (SRTM) Digital Elevation Model (DEM) version 1.0 was derived from resampling the 1 arc second (~30m) gridded DEM (ANZCW0703013355). Geoscience Australia is the government's technical adviser on all aspects of geoscience, and custodian of the geographical and geological data and knowledge of the nation.ģ second SRTM Derived Digital Elevation Model (DEM) Version 1.0 The library provides services to geoscience organisations, universities, research centres, the mining and petroleum industries and the public.
