Abstract
Project In 2013, Geoscience Australia commissioned AAM to undertake a LiDAR survey with accompanying field survey and ortho imagery capture over the Macintyre river region comprising approx 7,500 square kilometres. Ref Deed CMC G3298 Contract CMC G4417. Collection of both LiDAR and simultaneous and near simultaneous imagery utilising the Optech ALTM Pegasus HA500 sensor and the Vision Map A3 digital camera occurred from 06 November 2013 to 17th December 2013 with a total of 20 LiDAR flights plus a very small infill (LiDAR only) flight on 17th March 2014. The LiDAR was controlled from existing CORS GPS stations and 3 newly setup reference GPS station. 158 test point sites that overlapped the LiDAR were surveyed by AAM using Kinematic Smartnet GPS. The specification for this survey was provided in the aforementioned contract document Data The LiDAR, Ortho and field surveys conform in accuracy, format and nomenclature conform to the above specification. The ortho imagery comprises 0.20m GSD RGB Geotiff imagery in Geotiff and ECW formats. The area spans MGA zones 55 and 56 products have been generated with an overlap as per the specification and nomenclature advice from the client.

NEDF Metadata Acquisition Start Date: Wednesday, 6 November 2013 Acquisition End Date: Tuesday, 17 December 2013 Sensor: LiDAR Device Name: Optech ALTM 3100 Flying Height (AGL): 2300 INS/IMU Used: Honeywell URIS (S/N: 56016277) Number of Runs: 172 Number of Cross Runs: 17 Swath Width: 1300 Flight Direction: N Swath (side) Overlap: 25 Horizontal Datum: GDA94 Vertical Datum: AHD using Ausgeoid09 model Map Projection: MGA55 Description of Aerotriangulation Process Used:For ortho Visionmap Light Speed Turnkey Description of Rectification Process Used: Ortho Spatial Accuracy Horizontal: 0.45 Spatial Accuracy Vertical: 0.15 Average Point Spacing (per/sqm): 4.6 Laser Return Types: 4 pulses (1st 2nd 3rd 4th and intensity) Data Thinning: 0 Laser Footprint Size: 0.46 Calibration certification (Manufacturer/Cert. Company): 12SEN304 Limitations of the Data: The workflow and quality assurance processes were designed to achieve the Level 3 requirement for removal of significant anomalies which remain in the ground class (2) and achieve a ground point missclassification rate of 1% or less. The definition of the ground under trees may be less accurate. Surface Type: Mixed Product Type: Mass Points Classification Type: C3 Grid Resolution: 1 Distribution Format: LAS Processing/Derivation Lineage: The IMU and post processed airborne GPS logs were used to generate the LiDAR point cloud from the lidar instrument data. Raw LiDAR strips were levelled to establish internal consistency, merged and 1km x 1km tiles in LAS v1.2 format were created. The dataset were then output according to Flight number and swath line.
