LAS Dataset Properties dialog box from the Catalog pane.LAS Dataset Statistics geoprocessing tool.You can use any of the following methods to calculate statistics on your LAS dataset: Statistics can be generated and updated in several ways for the LAS dataset. A higher point density means lower values for point spacing. To convert point spacing to point density, use the following equation: PD = 1/(PS)^2. Point spacing (PS) is defined as linear units per point, and point density (PD) is defined as points per square unit area. Point spacing is not the same as point density. Statistics can be computed for an entire LAS dataset containing several LAS files, or they can be computed for a single file. lasx), statistics have already been calculated and will not need to be recalculated. If LAS files that are added to a LAS dataset already contain a LAS auxiliary file (. Were not generated using the Create LAS Dataset tool, use the LAS Dataset It stores theĬalculated statistical information and the spatial index for each lasx) is given the same name as the source LASįile and stored in the same location on disk. It also allows you to determine the overall quality and extent of the data prior to conducting time-consuming processes on the lidar data. Statistical analysis allows you to conduct initial quality assurance and quality control on lidar data to ensure that the data deliverables are exactly what was expected. Produce statistical information for LAS files referenced by the LASĭataset is essential to better understand the lidar and point cloud data that you are
