NSW Elevation Data Service
The NSW Elevation Data Service is an on-demand
download service delivering a number of Spatial Services Elevation Datasets
delivered in 100k map partitions.Datasets delivered through this service are:
·
New South Wales 2 metre
Contour Dataset
·
New South Wales 5 metre
Digital Elevation Model Dataset
·
New South Wales 5 metre
Resolution Slope Model Dataset
· New South Wales 5 metre Resolution Aspect Model Dataset
These datasets are designed to fit together seamlessly and to
provide an authoritative terrain dataset to support the development industry
standards in a variety of governmental, research and industrial uses.
New South Wales 2 metre Contour DatasetThe
coverage of this dataset is over the full state of New South Wales. The 2 metre
Contours are generated off a 5m DEM created from a combination of 1m and 2m
resolution LiDAR DEMs and 5m resolution Photogrammetric DEMs using TIN (
Triangular Irregular Network ) method of averaging ground heights to formulate
a regular grid. Data is provided in Esri Shape file format.New South Wales 5 metre Resolution Digital Elevation ModelThe
coverage of this dataset is over the Western New South Wales region. The 5 metre
Digital Elevation Model ( DEM ) is produced from a combination of 1m and 2m
resolution LiDAR DEMs and 5m resolution Photogrammetric DEMs using TIN (
Triangular Irregular Network ) method of averaging ground heights to formulate
a regular grid. This data set contains ground surface model in ascii grid format derived from various Airborne Digital
Sensors.New South Wales 5 metre Resolution Slope
Model DatasetThe coverage of
this dataset is over the Western New South Wales region. The 5 metre Slope (
SLP ) is produced from a combination of 1m and 2m resolution LiDAR DEMs and 5m
resolution Photogrammetric DEMs using TIN ( Triangular Irregular Network )
method of averaging ground heights to formulate a regular grid. This data set
contains ground surface model in ascii grid format derived from various
Airborne Digital Sensors.
New South Wales 5 metre Resolution Aspect Model DatasetThe
coverage of this dataset is over the Western New South Wales region. The 5
metre Aspect ( ASP ) is produced from a combination of 1m and 2m resolution
LiDAR DEMs and 5m resolution Photogrammetric DEMs using TIN ( Triangular
Irregular Network ) method of averaging ground heights to formulate a regular
grid. This data set contains ground surface model in ascii grid
format derived from various Airborne Digital Sensors.Metadata
