1 second SRTM Level 2 Derived Digital Elevation Model v1.0
Dataset Identification:
Resource Abstract:
The 1 second SRTM derived DEM Version 1.0 is a 1 arc second (~30m) gridded digital elevation model (DEM). The DEM represents
ground surface topography, and excludes vegetation features. 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. This product provides substantial improvements in the quality and consistency of the data relative to the original
SRTM data, but is not free from artefacts. Man-made structures such as urban areas and power line towers have not been treated.
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, 2009). A full description of the methods is in progress (Read et al., in prep; Gallant et al., in
prep). The grid spacing is 1 second in longitude and latitude (approximately 30 metres).Smoothed and drainage enforced versions
are under development, and are expected to be released in 2010.
