The SPOT-HRS Digital Surface Model (DSM) data was funded by Federal Government, Department of Climate Change. It was completed and delivered by SPOT IMAGE in 2008. The project area covers the coastal areas of Australia with the exeception of areas in North Queensland and Northern Territory. Data was collected and processed as part of the global Reference3D database being developed by SPOT IMAGE. The data was captured using the HRS (High Resoution Stereoscopic) instrument on board the Spot 5 Satellite. This instrument allows for the acquistion of stereoscopic pairs for the purpose of providing Digital Elevation or Terrain Models and Orthoimages. Importantly, while the standard product is termed a Digital Elevation Model (DEM), which in Australia is generally interpreted a being a ground surface, the SPOT-HRS DEM represents the theoretical surface of high points including trees and buildings, commonly referred to as a Digital Surface Model (DSM) in Australia. Data postings are at 1 second of arc, conforming to the DTED level 2 standard. The data projection is geographic, latitude and longitude using a horizontal datum of WGS 84, and a vertical datum of mean sea level as determind by the EGM96 geoid. The absolute horizontal accuracy is 15m at the 90% confidence level, relative horizontal accuracy is 8m at the 90% confidence level. The absolute vertical accuracy at the 90% confidence interval is reported as: 10m in flat rolling terrain < 20 degree slope; 18m in hilly terrain with 20-40 degree slope , and 30m in mountainous terrain > 40 degree slope. Relative vertical accuracy at the 90% confidence interval is reported as: 5m in flat rolling terrain < 20 degree slope; 15m in hilly terrain with 20-40 degree slope , and 28m in mountainous terrain > 40 degree slope. The data is available in DTED and ESRI GRID format at a 1 second (30 metre) grid spacing in 1 degree tiles, 1 second mosaic and also as a 3 second (90 metre) mosaic.

These datasets cover approximately 323 sq km over a strip of land joining the Town of Karumba to the Town of Normanton within the Carpentaria Shire Council and are part of the 2010 Gulf LiDAR capture project. This project, undertaken by Vekta Pty Ltd on behalf of the Queensland Government captured highly accurate elevation data using LiDAR technology. Available dataset formats (in 1 kilometre tiles) are: - Classified las (LiDAR Data Exchange Format where strikes are classified as ground, vegetation or building) - 1 metre Digital Elevation Model (DEM) in ASCII xyz - 1 metre Digital Elevation Model (DEM) in ESRI grid - 1 metre Digital Elevation Model (DEM) in ASCII grid - 0.25 metre contours in ESRI Shape

Digital Elevation Model Image - 9 second Version 2 National Geoscience datasets corporate store directory - /d/geo/store/data/national_data/dem/9second_v2 Dataset(s) in this directory - aus_dem_lm (LAMBERT projected greyscale ArcInfo Grid) pixel size is 260m NOTE : These data can be opened by ArcView or ArcGIS. Jpeg representations are also stored with each image for a quick view. The original 9 second Version 2 DEM data is stored in GEOGRAPHIC coordinates in /d/geo/store/data/topo/dem/9second_v2 These datasets are generated from the aus_dem ArcInfo Grid stored in that directory. Aus_demlm is projected from aus_dem and aus_demlmhs is a slope aspect index grid generated from aus_demlm, done in ArcInfo Grid. The hillshading is done using colormap files generated using the SAI command. Contact for further information - Bruce Kilgour

Metadata acquired by GA for the purposes of the National DEM Project from WA Landgate. DEM's are a mass of ground heights representing a terrain surface. In this instance they are spaced at a regular grid interval This dataset has been developed from aerial photography to assist in the digital imagery Orthorectification program. The status of coverage or other information relative to specific DEM data may be obtained directly through the DOLA contact.

The data have been derived from 1:250 000 scale NATMAP, NTMS, Royal Army Survey Corps Joint Operations Graphics, and TASMAP maps. The NATMAPs were created from EPS files which are by-products of the map production process. The remaining maps were scanned. All maps have been georeferenced to the Map Grid of Australia. Resolution is at 200 dpi and supplied in 24 bit (16 million) colour. The map images are available as a 2-CD set.

This map is part of the series that covers the whole of Australia at a scale of 1:250 000 (1cm on a map represents 2.5 km on the ground) and comprises 513 maps. This is the largest scale at which published topographic maps cover the entire continent. Each standard map covers an area of 1.5 degrees longitude by 1 degree latitude or about 150 kilometres from east to west and 110 kilometres from north to south. There are about 50 special maps in the series and these maps cover a non-standard area. Typically, where a map produced on standard sheet lines is largely ocean it is combined with its landward neighbour. These maps contain natural and constructed features including road and rail infrastructure, vegetation, hydrography, contours (interval 50m), localities and some administrative boundaries. The topographic map and data index shows coverage of the sheets. Product Specifications Coverage: The series covers the whole of Australia with 513 maps. Currency: Ranges from 1995 to 2009. 95% of maps have a reliability date of 1994 or later. Coordinates: Geographical and either AMG or MGA (post-1993) Datum: AGD66, GDA94, AHD. Projection: Universal Traverse Mercator (UTM) Medium: Paper, flat and folded copies.
