Abstract
These datasets cover approximately 1990 sq km over the town of Bundaberg and the surrounding area in the Bundaberg Regional Council and are part of the 2011 Bundaberg LiDAR capture project. This project, undertaken by AAM Pty Limited on behalf of the Queensland Government captured highly accurate elevation data using LiDAR technology. Available dataset formats (in 1 kilometre tiles) are: - Classified las in ellipsoidal datum(LiDAR Data Exchange Format where strikes are classified as ground, non-ground, vegetation or building) - Classified las in AHD datum - 1 metre Digital Elevation Model (DEM) in ASCII xyz - 1 metre Digital Elevation Model (DEM) in ASCII grid - 1 metre Digital Elevation Model (DEM) in ESRI grid - 0.25 metre contours in ESRI Shape

Lineage
Airborne LiDAR data was captured between 4th November and 13th December 2011. DATA PROCESSING Reduction of the ALS data proceeded without any significant problems. Laser strikes were classified into ground and non-ground points using a single algorithm across the project area. Manual checking and editing of the data classification further improved the quality of the terrain model. Vegetation: Vegetation points have been classified using an automatic algorithm tailored for the project area. No manual checking of Vegetation points has been undertaken. There may be instances of non-ground strikes being incorrectly classified as vegetation and conversely vegetation strikes remaining classified as non-ground. Buildings: Building points have been classified using an automatic algorithm tailored for the project area. No manual checking of building points has been undertaken. There may be instances of non-ground strikes being incorrectly classified as buildings and conversely building strikes remaining classified as non-ground. Non-ground: Non-ground points have been filtered by removing points within 0.1m of the ground surface to reduce incidence surface 'noise'. Points classified as non-ground may include laser strikes on the surface of water bodies.
