Abstract
The Kurnell 2008 LiDAR Survey was captured over Kurnell Peninsula (south of Sydney) on 8 December 2008. The source data was captured by AAM Hatch and funded by New South Wales, Department, Land & Property Management and made available under licence for use by Commonwealth, State and Local Commonwealth Government. The vertical accuracy is 0.15m at 1 sigma in open clear ground as specified in the project scope and 0.3m in the horizontal. All data are referenced to GDA94/MGA Zone 56 and AHD. The source data are available as mass points (ASCII XYZ, LAS) and Gridded 1m DEM tiles or 1m or 10m mosaic. A hydrologically enforced elevation model is available for this product, which should be used for any water modelling. Sydney Hydrological Enforced DEM (HDEM) 2007-2008 is a combination of this dataset and the 2007 & 2008 Sydney LiDAR datasets adn should be used for hyrological modelling.

Laser strikes have been classified into 'ground' and 'non-ground', based upon algorithms tailored for major terrain/vegetation combinations existing in the project area. The definition of the ground may be less accurate in isolated pockets of dissimilar terrain/vegetation combinations. Laser return: Last and first pulse. Data thinning: Points not contributing to the terrain definition within 0.04m removed Captured terrain model: 1.6m average point separation Limitations of use: The definition of the ground under trees and at the boundaries of water bodies may be less accurate.
