Abstract
These datasets covering all of the Logan City Council were captured under the 2008 Logan LiDAR capture project. This project, undertaken by Schlencker Mapping Pty Ltd on behalf of the Logan City Council captured highly accurate elevation data using LiDAR technology. Available dataset formats (in 1 kilometre tiles) are: - Classified las (LiDAR Data Exchange Format where strikes are classified as ground and non-ground) - 5 metre Digital Elevation Model (DEM) in ASCII xyz - 5 metre Digital Elevation Model (DEM) in ESRI ASCII grid - 0.5 metre contours in ESRI Shape Purpose: To provide highly accurate elevation data for use in risk assessment, the management of natural disasters, infrastructure planning, developing strategies to support climate change, topographic mapping and modelling.

Lineage
LI_Lineage: ACQUISITION Airborne Laser Scanning (ALS) data was acquired for the Logan project from a fixed wing aircraft between 16 January 2009 and 06 June 2009. DATA PRESENTATION The data has been supplied in accordance with a specification agreed with the primary client. The data is delivered in 1 km tiles to ensure file sizes and point counts. per file are manageable. FILE SIZES AND NAMES Data is provided in tiles 1km by 1km to the following file naming convention: eg. 426000_6983000_1k_5m_DEM.xyz 426000 - coordinate easting of north west tile corner. 6983000 - coordinate northing of north west tile corner _1km - tile dimensions, eg 1km x 1km _5m_DEM - Digital Elevation model with 5m grid spacing _cont - 50 cm contours .xyz - space delimited ASCII format .las - laser strikes 'classified in accordance with ASPRS V1.1 LAS file standards' various point class levels. DEM_ESRI.asc - ESRI ASCII Grid format SOURCE DATA Item: Laser System Description: Optech ALTM Gemini LASER SYSTEM CHARACTERISTICS Characteristic: Description Acquisition Start Date: 16/01/2009 Acquisition End Date: 06/06/2009 Device Name: Optech ALTM Gemini IMU Used: Applanix Litton 510 Number of Runs: 141 Flying Height: 800m Swath Width: 590m Side Overlap: 30% Flight Direct: East - West LASER DATA CHARACTERISTICS Characteristic: Description Format: space delimited ASCII, LAS Average Point Separation: 0.8m Laser return: All returns Laser mode: Multipulse REFERENCE SYSTEMS Horizontal: Datum: GDA94 Projection: MGA Zone 56 Vertical: Datum: AHD71
