Abstract
AAM Pty Ltd was commissioned by NSW Government's Office of Environment & Heritage to conducted an airborne LiDAR and Imagery survey over sections of the Gwydir Valley Floodplain west of Moree in north west NSW to assist with the development of Valley Wide Floodplain Management Plains under the Healthy Floodplain program. There has already been some LiDAR acquisition and this data will supplement this information. Collection of both LiDAR and simultaneous imagery utilizing the Optech ALTM Pegasus LiDAR sensor and DiMAC Ultralight medium format digital camera occurred from 31 May 2013 until 19 June 2013 (total of 7 separate flights). The primary use of the LIDAR data will be to provide topographical information necessary to define flood behaviour and undertake hydraulic modeling of floods in the area. Data is to be provided to LPI Classification 3 This project report provides specific information on: Project Details; Project Plan; Pre-Survey Quality Assurance Plan; Post-Survey Spatial Accuracy Report; Unforeseen/Extra-ordinary circumstances faced; Project Deliverable details; Statement of compliance; Control Reporting; Metadata documentation; Further project requirements.
