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.

Victor Harbour Lidar

Collection of Geoscience Australia's high-resolution elevation surveys collected using Light Detection and Ranging (LiDAR) and other instrument systems. <b>Value: </b>Describes Australia's landforms and seabed is crucial for addressing issues relating to the impacts of climate change, disaster management, water security, environmental management, urban planning and infrastructure design. <b>Scope: </b>Selected areas of interest around Australia.

The Lake George Basin project area was captured in January 2014. The data was captured in order to provide surface and intensity information to be used in earthquake hazard studies.

This metadata file and associated files contain metadata for the Geoscience Australia Kakadu LiDAR project carried out in 2011. This metadata is for the Digital Elevation Model created as 1m grid generated from the LiDAR point data classified as ground. The grid was generated employing a point to TIN and TIN to grid point process with nearest neighbour interpolation. The DEM was generated in ESRI ArcGIS V10 format.

High resolution elevation data covering an area of approximately 12,600 sq km in the Wakool-Murray catchment area. The survey is situated along the Victoria and NSW border, located between Yarrawong, Echuca, Robinvale and Moulamein and Deniliquin. A set of products were produced including classified lidar point clouds, hydro-flattened bare earth DEMs, DSMs, Canopy Height Models (CHM) and Foliage Cover Models (FCM). The outputs of the project are compliant with National ICSM LiDAR Product Specifications and the NEDF.

AAMHatch has been engaged by Geoscience Australia to undertake a LiDAR survey over the BHMAR Phase 2 project area, for the purpose of producing a DTM and vegetation structure analysis. The survey covers an area of approximately 7856 sqkm of the Lower Darling River, downstream from Wilcannia. To this end, LiDAR data was acquired from a fixed wing aircraft between June 19th and August 5th 2009.

Background This report describes a project which involved the capture and processing of LiDAR and coincident imagery and resultant derived products for the lower reaches of the Darling River. The data joins two existing LiDAR datasets, one to the north covering the Menindee Lakes and the other in the south along the Murray River corridor. It is intended to provide the Murray-Darling Basin Authority with a very accurate, quality assured measurement of topography in order to accurately model the flow and volume of water in the floodplains within the project area. The LiDAR was captured in April and May 2013 at a point density of two 1st return points per square metre within swath, (equivalent to two outgoing laser pulses per square metre at ground level). The specified accuracies; 30cm vertical and 80cm horizontal, were achieved and verified through a rigorous network of ground check points and base stations. A set of seamless products were produced including hydro-flattened bare earth DEMs, DSMs and cartographic contours. The outputs of the project are compliant with National ICSM LiDAR Product Specifications and the NEDF.

The data covers an area of approximately 4600 sq km in the Namoi Valley, located around Narrabri, NSW. The LiDAR was captured in September and October 2013 with a point density of two points per square metre. The specified accuracies; 30cm vertical and 80cm horizontal, were achieved and verified through a rigorous network of check points and base stations. A set of seamless products were produced including hydro-flattened bare earth DEMs, DSMs, Canopy Height Models (CHM) and Foliage Cover Models (FCM). The outputs of the project are compliant with National ICSM LiDAR Product Specifications and the NEDF. The survey was conducted over two areas along the Namoi River: one from Boggabri to Narrabri, and the other between Wee Waa and Walgett including a newer extension to this original area to the north east of Wee Waa.
