L0106 Sydney North

The coverage of this dataset is over the SydneyNorth 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 confidence ) horizontal with a minimum point density of one laser pulse per square metre. For more information on the data's accuracy, refer to the lineage provided in the data history .

本数据集覆盖悉尼北部区域。C3 LAS数据集包含LAS 1.2格式的点云数据，其数据来源为搭载ALS50（Airborne Laser Scanner，机载激光扫描仪）传感器的激光雷达（Light Detection and Ranging，LiDAR）。经处理后的数据已通过人工编辑，达到LPI分类等级3标准，其中地面点类别仅包含极少量非地面点，例如植被、水体、桥梁、临时设施、码头等。数据集用途：提供适配实际应用需求的高程数据，可应用于海岸脆弱性评估、自然资源管理（尤其水资源与森林资源管理）、交通运输及城市规划等相关场景。附加溯源信息：本数据集的水平定位精度为0.3米（95%置信度），最小点密度为每平方米1个激光脉冲。如需了解该数据集精度的更多详情，请参阅数据历史记录中附带的溯源信息。
