This map has been created to update the old Crimes at Sea maps produced in 2000. These maps have been checked & approved by the Attorney Generals Office April 2013. There are 13 maps in the series plus the main map showing all of the Australian Territory. The AAT maps have not been released to the public as yet.

The Christmas Island Geographic Information System (CIGIS) is a collection of spatial data, viewing and analysis tools dealing with Christmas Island, Indian Ocean. The data include orthophotography, topographic, mining, cultural and environmental features of the island. This work is part of ongoing service to the Department of Transport and Regional Services.

Christmas Island is located approximately 2,600 North West of Perth. It is the surface expression of an emergent seamount uplifted by tectonics. Bathymetry data are required in this area to help identify major seabed processes and habitats. The data are also required to enable modelling of tsunami as they interact with the shelf around the island and the coast. This report describes the methodology employed in creating detailed bathymetry data grids of the Christmas Island region. It covers data collection, quality control and gridding. Descriptions are provided of each dataset employed, the methods used to integrate the different datasets and the attributes of the new bathymetric models. Five new bathymetry grids are presented, including grids that integrate bathymetry with the island's topography.<p><p>This dataset is not to be used for navigational purposes.

Laser DEM Shiny Colour Drape Images contains Digital Elevation Model (DEM) tiles covering the eastern half of Christmas Island as 8 bit TIFF, 24 bit TIFF, and ECW images. A LiDAR Digital Elevation Model (DEM) was constructed for the eastern half of Christmas Island from ground heights obtained from an airborne laser scanning survey flown September 2000 by AAM Surveys Pty Ltd. Shiny colour drape images of the ground surface were produced from this DEM in Geoscience Australia by processing the set of last returns (mostly ground heights), and the GPS location in MGA (GDA94) units of each height. Point shape files and Arc grids were also created from the raw data by GA. Laser DEM Grids consists of 27 digital elevation model grids. The Arcview grid files were constructed from the "Airborne Laser Scanning" shapefiles. The Laser DEM grid tiles cover the eastern portion of the Christmas Island. Each grid contains the height in metres of the ground surface with a value every one metre on the ground.
