Redland 2009 LiDAR survey was captured over the Redland City Council region between 25th March and 9th June 2009. The data was acquired by AAM Hatch (now AAMGroup) and funded by Queensland and Commonwealth governments. The data is licensed for use by all Commonwealth, State and Local Government. Data acquisition and post-processing has been controlled to achieve a vertical accuracy within 0.15m (RMS, 68% CI) and horizontal accuracy within 0.45 m. Horizontal coordinates are based upon Map Grid of Australia (MGA) Zone 56 projection. Vertical coordinates are referenced to Australian Height Datum (AHD). The data was captured with point density of 2.5 points per square metre and the data is available as mass point files (ASCII, LAS) and ESRI GRID files with 1m grid spacing in 1km tiles. The data are available as a number of surface types, products and formats including: mass points, digital elevation model (DEM) and hydrologically enforced DEM (HDEM) for the low lying coastal areas. Redland DEM forms part of the Brisbane HDEM which is a combination of the Brisbane 2009 LiDAR, Redland 2009 LiDAR, Moreton Bay 2009 LiDAR and Logan 2009 LiDAR survey areas.

The 2011 digital elevation model (DEM) grid covers the whole of the Christmas Island. It was provided by AAM in 1km by 1km ESRI grid tiles which were then joined together using ESRI ArcMap. Each grid cell (1m by 1m) contains the height in metres of the ground surface derived from the 2011 LiDAR aerial survey data.

A useful spin off of the soft photogrammetry is the opportunity to get one metre contours over the disturbed areas of the Island. For the north-east area of the Island 2km X 2km DEM contour tiles have been trialed in the CIGIS. Most are at a contour interval of 5 metres but tiles 2269 and 2469 have been done at a one metre contour interval. The DEM contours are surface contours. They pick up the reflective surface beneath the aircraft. The reflective surface may be the ground or it may be a dense vegetation canopy or rooftops etc. Further one metre contour coverage can be prepared on a cost recovered basis.

Airborne Laser Scanning contains ESRI shapefiles constructed from ground height data points. The heights were obtained from an airborne laser scanning survey conducted by AAM Surveys Pty Ltd. The shapefiles contain surface heights in metres for the eastern half of Christmas Island.

Darwin and surrounds LiDAR 2009 data was flown by Dugro Spatial Solutions Ltd between 4th and 5th of July 2009 as part of the Urban Digital Elevation Modelling in High Priority Areas Project funded by the Federal Department of Climate Change. Distibution of this product is in file format of 1km tiles, and 1m DEM data in ESRI floating point file format. The data has a horizontal accuracy of 0.15m (at one SD) and vertical accuracy of 0.2m (at one SD).
