1m contours were generated for the Christmas Island urban area from the August 2011 LiDAR digital elevation model.

1997 DEMtiles (a concatenation of 97DEM tiles) contains some samples of a representation of the Digital Elevation Model as TIFF and ECW images.

DEMs 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 as part of the Land Monitor salinity study program. The status of coverage is available either directly or via remote access to Land Monitor's website http://www.landmonitor.wa.gov.au/ Information relative to a specific map DEM data may be obtained directly through the DOLA contact.

This data disk contains SunRISE 21 Licensed Data prepared for: - CLIENT: Geoscience Australia / CRC LEME - SUPPLY DATE: 30/8/2006 - Under Terms and Conditions of Data Licence Agreement(DLA): 0046 OR as set out below The data has been derived photogrammetrically from aerial photography: - Date of Photography: Various - Scale of Photography: Various DATUM: - Horizontal Datum: GDA94 MGA54 - Vertical Datum: AHD (Australian Height Datum) ABOUT the CONTOURS / DEM: - DEM: 10m x 10m height grid points - Contour Interval: 1 metre form lines derived from 2 metre contours. The contours have been interpolated from the height grid, and a smoothing spline fitted. ACCURACY ESTIMATE: - Horizontal 0.5 metres Vertical 1.0 metre In areas subject to dense vegetation, shadow or where the terrain is not confidently visible, the stated horizontal and vertical accuracy should be regarded with caution.

This layer is part of Vicmap Elevation 1- 5 Contours and Relief, a subset of Vicmap Elevation. It contains point features delineating ground surface points photogrammetric control points. Includes; Spot heights and Rocky Outcrops. This layer is part of Vicmap Elevation 1-5 Contours and Relief, a subset of Vicmap Elevation. It contains relief features represented by lines at 1 metre intervals with some areas at 5 metres intervals. Data has been derived from Melbourne Water base maps and converted to Microstation .DGN format. Data is incomplete ie. there are "holes" in the data where for example there are quarries, or large building sites.

Metadata acquired by GA for the purposes of the National DEM Project from WA Landgate. DEMs 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.

This Digital Elevation Model Image is a subset from the GLOBE Project (1km) . The data is stored at /d/geo/store/data/national_data/dem/1kilometre and dataset(s) in this directory include: dem1k (LAMBERT projected image), dem1kdd (GEODETIC projected image), dem1kg (LAMBERT projected image - greyscale) and dem1kddg (GEODETIC projected image - greyscale. Note that Jpeg representations are also stored with each image for a quick view. Images can be viewed using ERMapper, ERViewer and ARCGIS (with the cew plug-in, available free from www.ermapper.com ). Full GLOBE metadata is stored in GEOMET.
