Topographic mapping services

High-resolution elevation mapping, contour mapping and terrain visualisation for surveying, infrastructure and development projects across Australia.

Terrain data your project team can rely on

Topographic mapping gives you a detailed representation of terrain: elevation change, contour lines, and natural and built surface features. It is an essential input for infrastructure planning, development feasibility and surveying work.

From preliminary feasibility assessments through to detailed design inputs, we produce terrain products delivered in the formats your project requires. A simple contour map for a residential site or a comprehensive digital elevation model for a large infrastructure corridor, both to professional standards.

What we deliver

Contour mapping
Accurate contour lines at any required interval: 0.5 m, 1 m, 2 m or 5 m depending on site complexity.
Digital elevation models
Bare-earth surface models derived from LiDAR or photogrammetric data for analysis and design.
Digital terrain models
Terrain surface products incorporating breaklines and survey-grade data points.
Slope and aspect analysis
Gradient mapping for drainage assessment, geotechnical analysis and site suitability.
Cross-section profiles
Elevation profiles along defined transects for infrastructure and development design.
Cut and fill analysis
Volume calculations and earthworks mapping for site development.
LiDAR data processing
Point cloud classification and surface product generation from raw LiDAR datasets.
Terrain visualisation
Hillshade and 3D terrain renders for reports and presentations.

How the job runs

  1. Project scoping

    We establish site extent, required accuracy, contour interval, and the specific outputs your survey or project team needs.

  2. Data sourcing

    We identify the best available source, whether public LiDAR, photogrammetric data or your own survey data, and assess its suitability for your accuracy requirements.

  3. Processing and mapping

    We process the elevation data, generate surface models, and produce clean topographic maps and datasets to your specifications.

  4. Delivery

    Final outputs arrive in your required formats: GIS rasters, contour Shapefiles, PDF maps and CAD-compatible files as needed.

Data we draw on

Source selection is matched to the accuracy your project needs.

Frequently asked questions

What is topographic mapping used for?
Feasibility studies, site development planning, infrastructure corridor design, drainage analysis and surveying support. It provides the elevation data needed for cut and fill calculations, stormwater design, earthworks estimates and site layout planning.
What is the difference between a DEM and a DTM?
A Digital Elevation Model represents the bare earth surface without vegetation or structures. A Digital Terrain Model typically incorporates breaklines and natural terrain features such as ridgelines and stream channels for more accurate representation. Both are used in infrastructure and planning projects, and the right choice depends on your requirements.
Can you create contour maps from LiDAR data?
Yes. LiDAR is the most accurate source for contour mapping and topographic analysis. We work with publicly available national and state LiDAR datasets as well as client-supplied point cloud data.
How accurate is topographic mapping?
Accuracy depends on the data source. LiDAR-derived products typically achieve vertical accuracy of ±0.10 m to ±0.30 m. Photogrammetric data typically achieves ±0.20 m to ±0.50 m. We advise on the most appropriate source and achievable accuracy at the quoting stage.
Do you cover regional and rural areas?
Yes. We have access to extensive LiDAR coverage across Australia through state and national data programs, enabling accurate topographic mapping even in remote locations.
How long does topographic mapping take?
Most projects are completed within 3 to 5 business days. Larger sites or work requiring specialised processing may take longer. Turnaround is confirmed with your quote.
What file formats do you deliver?
Contour Shapefiles and GeoPackages for GIS use, GeoTIFF and ASCII grid for DEM and DTM products, high-resolution PDF maps for reports, and DWG/DXF for CAD compatibility. We can match specific format requirements on request.
