2015 City of Philadelphia Classified LiDAR LAS and Derivative Products

Abstract: 
Abstract: Classified LiDAR LAS and Derivative Products This dataset is lidar point cloud data covering the City of Philadelphia, PA, approximately 196 sq miles total. The dataset consists of 1024 lidar point cloud LAS files. Each LAS file contains lidar point information, which has been calibrated, controlled, and classified. The data was collected at a nominal point spacing of 0.70m using Pictometry's Riegl LMS-Q680i LiDAR system over 4 mission days on April 18th, 19th, 22nd, and 25th, 2015. At the time of capture ground condiitons were leaf-off, snow free, and water was at normal levels. Data Development: GPS/INS Processing: During the flight, GPS and INS data was logged on board the aircraft. Simultaneously, GPS data was logged by a stationary reference station network on the ground. After completion of the flight, this data was post-processed using Applanix POSPac v7.1 to generate a smoothed best estimate trajectory (SBET). DashMap/TerraSolid: The raw laser range data was combined with the SBET to create the raw point cloud using Optech's DashMap software package. Once the LAS point cloud is created, TerraSolid's TerraMatch software is used to measure and apply small adjustments to the system's orientation angles in order to ensure proper alignment of data between flight lines. Data Classification: A series of automated algorithms were applied using TerraSolid to classify ground points. The results of these algorithms were reviewed using models created in TerraModeler to ensure the quality of the classification results.
