CONTOURS

AUSTRALIA’S DIGITAL ELEVATION MODEL

  • The Digital Elevation Model (DEM) 5 Metre Grid of Australia derived from LiDAR model represents a National 5 metre (bare earth) DEM which has been derived from some 236 individual LiDAR surveys between 2001 and 2015 covering an area in excess of 245,000 square kilometres.
  • This raw data is available for download from the Elevation Information System (ELVIS) as digital elevation models (DEM). Weddin Mappping Solutions can use these DEMs to generate geo-referenced contour lines. These can be displayed in scaled, printed maps or outputted as a KML file which can be used in Google Earth or other mapping software.

GENERATING CONTOURS FROM A DEM

    • Digital elevation models can be clipped to a defined area – for example a lot boundary. A contour layer can then be generated from the DEM for that particular area of land. This layer can be added along with other spatial data and imagery to create maps such as property plans.
    • The DEM has a resolution of 5 metres and is able to produce very detailed contour lines – capable of showing the earth banks around farm dams for example.

DIGITAL OUTPUT

  • The contours can be outputted as a KMZ file which can be added into online mapping applications such as Google Earth and accessed easily via your phone or other device
  • If you would like contour lines for your property generated from the 5m DEM just use the NSW sixmaps tool below to find your DP, lot and boundary number and message the information to us at Weddin Mapping Solutions.
  • Orders can be customized to suit your needs. Let us know how you’d like the contours presented – for example as a scale A4, A3, A2, A1 or A0 landscape/portrait map with or without aerial imagery and we’ll provide a quote.
