Terrain datasets currently offered

The cards below come from the same live catalogue used by the export service. Source resolution, capture method and contour interval vary by state and location.

Contours (interval varies by state)

Elevation contour lines, Z embedded on each vertex.

NSWQLDVIC SHPDXFGPKGKMZ

Elevation Points

3D spot heights sampled from the state DEM.

NSWQLDVIC SHPDXFGPKGKMZ

Elevation Raster (GeoTIFF)

Float32 DEM in metres AHD, clipped to the extent.

NSWQLDVIC GEOTIFF

TIN Surface (DXF only)

Delaunay triangulated surface over the DEM, as DXF 3DFACE entities.

NSWQLDVIC DXF

Choose the terrain output by job

  • DXF contours: readable 3D linework for AutoCAD and Civil 3D base drawings.
  • Elevation points: sampled 3D spot heights for point-based surfaces and checks.
  • GeoTIFF DEM: the elevation grid for surfaces, slope, aspect and re-contouring.
  • DXF TIN: a Delaunay surface written as 3DFACE entities for CAD terrain workflows.

What arrives in the ZIP

  • Compatible vector layers organised into dxf/, shp/ and kmz/.
  • A combined GeoPackage when GPKG is selected.
  • The elevation raster as a root-level GeoTIFF.
  • DATASETS.txt and datasets.json recording the result for each selection.
  • COPYRIGHT.txt naming the government sources and licence.

Evidence from the current sample

Inspect the real terrain files

The current Queensland sample contains 14 contour features, 500 elevation points, a GeoTIFF elevation raster and a 2,999-face DXF TIN. It also shows how terrain aligns with cadastre, roads and the project lot.

Accuracy and intended use

Terrain mapping is a fast starting surface, not a substitute for verified site levels.

Useful for

  • Desktop terrain review
  • Concept-stage CAD and GIS setup
  • Preliminary drainage and slope understanding
  • Consultant briefing and feasibility mapping

Verify before

  • Detailed design or earthworks quantities
  • Setout and construction
  • Boundary-dependent grading decisions
  • Any work requiring current surveyed ground levels
Elevation quality and vintage depend on the government source available at the selected location. Vegetation, structures, capture date and grid resolution can affect the surface. Check the export attribution and validate against an appropriate survey before detailed design.
