<b>New
South Wales 2 metre Contour Dataset</b>


The
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.


 


<b>New
South Wales 5 metre Resolution Digital Elevation Model</b>


The
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.


 


<b>New
South Wales 5 metre Resolution Slope Model Dataset</b>


The
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.


 


<b>New
South Wales 5 metre Resolution Aspect Model Dataset</b>

The 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.<b>Dataset Producers and Contributors:</b>Administrative Spatial Programs | DCS Spatial Services
