3D Laser Scanning Services & LiDAR Surveying in Australia & New Zealand

3D laser scanning is a type of remote sensing that measures the properties of land, terrain and objects using laser pulses. The pulses are reflected back from the surface and are converted into 3D coordinates. The LiDAR system produces hundreds of thousands of these points, which are then analysed to produce an image.

The technology has many advantages over traditional surveying equipment. First, it’s faster and more accurate. LiDAR is usually accurate to within two centimetres, and it requires fewer resources. Secondly, it can be used in difficult or inaccessible environments. Using mobile laser scanners also makes it possible to perform surveys remotely and transmit high-fidelity images.

Using 3D laser scanning is an excellent way to get a better view of land. It can provide highly detailed information about a region by detecting features and measuring their distances. It is used by engineers and earth scientists for a variety of industries. A LiDAR system consists of a laser source, a scanning device, and a GPS receiver. The scanner sends a beam of light at specific targets, which produces a digital 3D model of the area. The data generated by this method can be used to analyse the landscape or create plans for construction.

Another advantage of LiDAR surveys is their speed. The system works quickly and can be mounted to an aerial craft. This means that it can be used to survey difficult areas and to avoid damaging the environment. Additionally, the data generated by a LiDAR survey can be easily integrated with other sources of data to create a high-quality 3D model.

LiDAR scanning data is invaluable for construction planning. A LiDAR system can generate 3D models that are accurate to 15cm. These models are also important for assessing the risk of landslides and floods. LiDAR surveys provide more detailed information than conventional topographical surveys. They can also provide detailed terrain models through thick vegetation.

LiDAR is especially useful for mapping areas beneath tree canopies and narrow structures. Photogrammetry cannot always recognise such objects. LiDAR can also be used in poor lighting conditions and at night. This technology allows for faster data acquisition operations. In addition, photogrammetry requires more Ground Control Points (GCPs) than LiDAR does.

A drone-mounted LiDAR is a more affordable alternative than manned aircraft, and can survey difficult areas with great accuracy. This method can be used to create 3D maps of land with low personnel requirements. A drone can also fly much lower than manned aircraft, and the high-resolution LiDAR data can be used to make accurate digital surface models and landscape maps. A drone can also provide ground control points to confirm the accuracy of the survey.

The output of LiDAR surveys can be incredibly useful in construction planning. It can be used to analyse the suitability of land for a construction project, and it can even highlight small details, such as the condition of existing roads and buildings. This data can also help construction crews better plan their budgets.
