Langridge, R.M. 2011 Precise mapping of near-field fault deformation in New Zealand using LiDAR technology : final report, Hazards Platform Contestable Fund. Lower Hutt, N.Z.: GNS Science. GNS Science report 2011/44 59 p.
Abstract: The Natural Hazards Platform (NRHP) Contestable Fund 2010 funded GNS Science and its Platform Partners to investigate the usefulness of LIDAR (Light Ranging and Detection) as a means of mapping active faults in remote, forested areas of New Zealand. Following a period of project planning three active fault strips were flown with LiDAR: the central part of the Alpine Fault; the western part of the Hope Fault; and part of the Tararua section of the Wellington Fault. The airborne LiDAR acquisition and processing was undertaken by New Zealand Aerial Mapping Ltd (NZAM). This project has been a remarkable success. Thorough planning prior to airborne data acquisition and collaboration between GNS Science, NZAM and the Platform Partners have been some of the major successes of the project. The resulting data is of very high quality and will be the research standard for active fault mapping for the next decade to come. Many lessons have been learned concerning the acquisition and usefulness of LiDAR as an active fault mapping tool in forested terrain in New Zealand. Without question, the airborne LiDAR technique can be applied to the most difficult forested terrains in New Zealand. A clear result is that the quality of the end product is dependent on the requirements designed for in the project plan. (auth/DG)
