The CRCSI has been involved in the coordinated acquisition and integration of approximately 100 individual LiDAR surveys covering over 200,000km2 of major urbanised coastal areas of Australia. These datasets are available for whole of government use through streamlined licensing arrangements.

The CRCSI has designed, managed and advised on a range of LiDAR projects in Australia and the Pacific in recent years. The organisation has significant experience in project management and data quality assurance. Being independent of any LiDAR provider, the CRCSI is able to commission and quality assure LiDAR products using any acquisition system. One of the CRCSI’s objectives is to acquire the best value service for clients from any of its private sector partners.

Dr. Nathan Quadros is a world leader in airborne LiDAR capture and quality assurance, specialising in bathymetry capture. The CRCSI has provided LiDAR project management and quality assurance services for many organisations, including the PACCSAP project for the Australian government. Most recently the CRCSI has managed a bathymetric LiDAR acquisition for the Gold Coast Waterways Authority within the Gold Coast in Queensland, Australia. These projects are among many which the CRCSI and Dr Nathan Quadros have managed and advised on in recent years.

The CRCSI has established LiDAR quality assurance standards in Australia. Nathan led the publication of the LiDAR Validation chapter in the Good Practice Handbook, which can be found at:

This chapter provides a basic understanding of LiDAR sensors, combined with knowledge of the various considerations which impact upon the quality of the products. To ensure that the LiDAR products meet the specifications and user requirements, the quality needs to be assured and the deliverables validated. The validation can either be against the required specifications, or against a set of requirements defined by the end use of the LiDAR data. The validation practices typically inspect the LAS and DEM data products, and any additional deliverables that are produced.

The chapter provided in the Good Practice Handbook outlines the recommended steps which may be taken by a purchaser or end user to validate the project deliverables. The validation checks include the delivery completeness, coordinate systems, vertical datums, extent, coverage, survey control, vertical accuracy, density, classification and reports. Additional checks may be performed for unique deliveries, or for specific applications requiring an analysis of particular components of the LiDAR products.

The CRCSI released a standard LiDAR QA software tool to project partners in 2014. This tool implements the validation concepts presented in the Good Practice chapter.  The tool provides an easy to use, automated approach for the LiDAR checks. This software has set the standard for LiDAR quality in Australia and the Pacific. The research page on the LiDAR QA Tool "QA4LiDAR" can be found at:

The standards developed by the CRCSI have improved the quality of LiDAR data in Australia and the Pacific. The recognised benefits of standard LiDAR specifications and the quality assurance tool include:

  • Providing a more comprehensive quality assurance procedure which ensures a higher quality LiDAR dataset.
  • To reduce the costs and times of feature extraction by decreasing the number of errors being found by users after a project has been signed off and completed.
  • To reduce the repetition of quality checking data, by providing a standard QA report which represent known checks on the LiDAR data.
