Description

Changes of Note
  • The Zstandard compression library is no longer required in order to build PDAL.
  • The Ubuntu conda image now installs all of PDAL under /usr.
  • The default type of the ClusterID dimension has changed from uint64_t to int64_t.
  • Most operations now store data using ColumnPointTable, which stores data in arrays of dimensions, rather than arrays of point data. This can improve the performance of some operations substantially. Generally, this change should not be noticeable to users.
  • Normal refinement (refine option) in filters.normal is now off by default. (#3133)
  • All filters now accept a where option to allow points to skip the filters. (#3118)
  • PDAL now searches for plugins in the same directory containing the PDAL library. (#3181)
API User Notes
  • ColumnPointTable is now the default PDAL point table. If you have written code that expects row-major data rather than column-major data, be sure to use RowPointTable instead.
New Stages
  • filters.lloydkmeans labels points with a ClusterID based on Lloyd's algorithm. (#3075)
  • filters.litree provides segmentation of points into trees and non-trees. (#3111)
  • filters.faceraster creates a raster from an existing triangulation. (#3152)
  • filters.optimalneighborhood computes the optimal number of neighbors and corresponding radii (#3180)
  • reader.obj allows reading of OBJ files.
Removed Stages
  • filters.hag has been removed. Use filters.hag_dem, filter.hag_delaunay or filters.hag_nn instead.
Deprecated Stages
  • filters.ferry. Use the value option of filters.assign instead.
Enhancements
  • filters.colorinterp now provides the clamp option to force values to be in the range [min, max]. (#2729 - Thanks to Matt Csencsits)
  • Long options can now be specified on the command line without and equal sign ('=') separating the option name and value. (#3016)
  • Added seed option readers.faux in order to allow consistent generation of random data. (#3014)
  • Improvements have been made to cmake installation to better support downstream projects. (#2262)
  • Added color_vertices option to writers.gltf to allow writing of RGB and normals. (#3043 - Thanks to Emma Krantz)
  • Added classbits option to filters.smrf to specify points to be ignored by the SMRF algorithm. (#3055)
  • Delaunay triangulation performance has been improved on systems using libstdc++. (#3076)
  • filters.covariancefeatures now provides the options min_k and radius to support radius search of neighbors in addition to k-nearest. (#3083)
  • filters.cluster now provide the option is3d to support 2-dimensional clustering. (#3084)
  • filters.icp now emits a fully composed transformation matrix as metadata that can be provided to filters.transformation to modify point locations using a single operation. (#2939, #2962)
  • filters.eigenvalues added the options stride, radius and min_k to allow radius and strided neighbor searching. (#3132)
  • writers.las now accepts the filename key in the vlrs option to import VLR data from files. (#3146)
  • filters.transformation now provides the invert option to apply the inverse of the provided matrix. (#3126)
  • readers.ept now returns a clipped boundary in the summary to match the behavior of the point count. (#3168)
  • filters.head is now streamable.
  • readers.i3s is now streamable.
  • readers.slpk no longer expands the source file into a temporary directory.
  • filters.assign added the value option to allow standard expression-based conditional assignment of values.(#1468)
Bug Fixes
  • A problem where the classifications of voting points were being changed in filters.neighborclassifier has been fixed. (#3210)
  • Fixed an issue where NITF-wrapped LAS files may fail to open (#3010)
  • Reading and writing of E57 files over 2GB in size on Windows has been fixed. (#3000)
  • Fixed various compilations issues in filters.matlab. (#3013)
  • Added better handling for some cases of coordinate transformation failure. (#3009)
  • An error in calculating position for some data in filters.smrf has been fixed. (#3069)
  • An error in calculating neighbors for isolated points in filters.smrf has been fixed. (#3071)
  • readers.las now creates dimensions ScanChannel and ClassFlags only when reading point formats 6-10. It used to create them for any version 1.4 file. (#3092)
  • filters.poisson now throws exceptions instead of calling exit() when it encounters a fatal error. (#3094)
  • Errors that could occur in gdal::Raster::statistics() are now returned to the caller, rather than resulting in a crash. (#3097)
  • pdal tindex now ensures that traditional GIS axis order is used. (#3099)
  • readers.tindex now uses the file SRS rather than the tile index column SRS unless overridden by the srs_column option. (#3012)
  • An error in readers.ept that could create bad data when both the bounds and addons options were specified has been fixed. (#3054)
  • filters.hag_nn and filter.hag_delaunay now log an error rather than terminate if no ground points are found. (#3112)
  • An error in reporting point count was when the number of points exceeded the maximum 32-bit value in readers.ept has been fixed. (#3120)
  • pdal tindex now stores WKT instead of EPSG codes to handle vertical SRS instances. (#3100)
  • A bug in filters.crop that didn't properly handle 2D cropping has been fixed. (#3115)
  • readers.text now properly handles quoted dimension names in the header. (#2201)
  • Windows-style directory separators are now properly handled in cases using relative filenames. (#2936)
  • An exception reading E57 points with a transform has been fixed. (#3163)
  • Fix a failure in readers.pcd when preview() was called before execute(). (#3169)
  • The compression level for writers.tiledb is now properly set to 7. (#3198)
  • An issue where filters.neighborclassifier would modify classifications as it calculated them has been fixed. (#3210)
