Readers provide Dimensions to Pipeline. PDAL attempts to normalize common dimension types, like X, Y, Z, or Intensity, which are often found in LiDAR point clouds. Not all dimension types need to be fixed, however. Database drivers typically return unstructured lists of dimensions. A reader might provide a simple file type, like readers.text, a complex database like readers.oci, or a network service like readers.greyhound.

Read BPF files encoded as version 1, 2, or 3. BPF is an NGA specification for point cloud data.
Special stage that allows you to read data from your own PointView rather than fetching data from a specific reader.
Used for reading Entwine Point Tile format.
Used for testing pipelines. It does not read from a file or database, but generates synthetic data to feed into the pipeline.
Read point cloud data from Accumulo.
Query point cloud data from a Greyhound server.
Read data stored in the Esri I3S format. The data is read from an appropriate server.
Read from files in the ILVIS2 format.
Read ASPRS LAS versions 1.0 - 1.4. Does not support point formats containing waveform data. LASzip support is also enabled through this driver if LASzip or LAZperf are found during compilation.
Read point cloud data from MATLAB .mat files where dimensions are stored as arrays in a MATLAB struct.
Read sonar bathymetry data from formats supported by the MB-System library.
Read data compressed by the MrSID 4.0 LiDAR Compressor. Requires the LizardTech Lidar_DSDK.
Read point cloud data (LAS or LAZ) wrapped in NITF 2.1 files.
Read point cloud data from Numpy .npy files.
Read data from Oracle point cloud databases.
Read Optech Corrected Sensor Data (.csd) files.
Read files in the PCD format.
Read point cloud data from a PostgreSQL database with the PostgreSQL Pointcloud extension enabled.
Read points and vertices from either ASCII or binary PLY files.
Read data from Leica Cyclone PTS files.
Read data in the QFIT format originated for NASA’s Airborne Topographic Mapper project.
Read data in the RXP format, the in-house streaming format used by RIEGL. The reader requires a copy of RiVLib during compilation.
