Abstract
The coverage of this dataset is over the WestNarranLake region . The C3 LAS data set contains point data in LAS 1.2 format sourced from a LiDAR ( Light Detection and Ranging ) from an ALS50 ( Airborne Laser Scanner ) sensor . The processed data has been manually edited to achieve LPI classification level 3 whereby the ground class contains minimal non-ground points such as vegetation, water , bridges , temporary features , jetties etc . Purpose: To provide fit-for-purpose elevation data for use in applications related to coastal vulnerability assessment, natural resource management ( especially water and forests) , transportation and urban planning . Additional lineage information: This data has an accuracy of 0.3m ( 95 CI ) vertical and 0.8m ( 95 CI ) horizontal with a minimum point density of one laser pulse per square metre . For more information on the datas accuracy, refer to the lineage provided in the data history .
