PDAL - 2.4.0

Published by abellgithub over 2 years ago

Changes of Note

  • The PDAL_STATIC_BUILD cmake option has been removed. We do not support building PDAL as a static library, though it may work.

Published by abellgithub about 4 years ago

Changes of Note

  • 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.

  • 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)

PDAL - 2.1.0

Published by hobu over 4 years ago

Changes of Note

  • The X, Y and Z dimensions are now always stored internally as double-precision floating point. This was normally case previously, but it is now enforced. (#2892)
  • The interface include file directory is now set for downstream projects using cmake, eliminating the need to explicitly set the location of PDAL header files. (#2262)
  • PDAL is now always built using the arbiter library, which is included in the source distribution.
  • filters.python has been removed from the primary PDAL library and is part of the PDAL python library.
  • When the bounds option of filters.crop represents a 3D volume, the filter now does 3D cropping, rather than 2D cropping as in previous releases. (#2904)
  • writers.ply no longer accepts default as a valid value for the storage_mode option. (#2385)

API User Notes

  • Support has been added for range-based iteration of PointView objects. The dereferenced iterator yields a PointRef object.
  • We are now providing private header files as part of the distribution. The API exposed by these files may change or be eliminated in a future release. Use of these files may require the installation of the header files from other packages. The symbols for some of these functions may not be public, especially on Windows.
  • There are now enumerations for classifications (pdal::ClassLabel).
  • N-dimensional KD-tree support has been added.
  • There are some small API changes (const changes, for example), but almost all code using the PDAL library should build without modification.
  • We do not guarantee ABI compatibility, though in most cases this release should be backward compatible.

New Stages

  • filters.voxeldownsize provides streamed support for voxel filtering. (#2699 - Thanks Helix.re!)
  • filters.separatescanline splits input into separate output point views based on associated scan lines. (#2724 - Thanks Guilhem Villemin)
  • filters.farthestpointsampling add points from the input to the output one-at-a-time by selecting the point in the input that is the furthest from any point in the output. (#2761)
  • filters.skewnessbalancing classifies ground points using the method of Bartels. (#2740)
  • filters.dbscan provides density-based clustering. (#2748)
  • filters.csf provides ground classification of points using the cloth simulation method of Zhang. (#2765)
  • readers.hdf provides generic support for many HDF files. (#2934)
  • filters.hag_nn, filters.hag_delaunay and filters.hag_dem have been created to replace filters.hag. (#2886)

Deprecated Stages

  • filters.hag is deprecated and will be removed in a future release. Use filters.hag_nn, filters.hag_delaunay and filters.hag_dem instead.

Removed Stages

  • readers.sqlite and writers.sqlite

  • writers.las now allows specification of a filesource_id as an option. (#2862)
  • readers.text now handles quoted dimension names in a header line. (#2201)
  • pdal info now reports the reader used for a file, the current time and the size of the file. (#2900)

Bug Fixes

  • An error in calculating variance, standard deviation, skewness and kurtosis has been fixed in filters.stats. (#2790)
  • An error where a list of dimensions would be expanded improperly in writers.ply under certain API uses. (#2791)
  • Crashes in filters using the delaunay triangulation code have been fixed. (#2805)
  • writers.pcd now always writes dimension names as lowercase. (#2789)
  • The extended VLR offset was not being written to LAS files. This has been fixed. (#2823)
  • Fixed some small memory leaks.
  • filters.elm now works properly when input is an empty point view. (#2921)
  • filters.pmf now classifies all points either as "Ground" or "Unclassified". Points are no longer marked as "Created, Never Classified". (#2898)
  • LAS VLRs specified in a pipeline are now properly handled by writers.las. (#2937)
  • When not building with LASzip or LAZperf, writers.las would fail to properly set a spatial reference in some cases. This has been fixed.
  • writers.las now always uses WKT version 1. In the previous release it may have used WKT version 2 in some cases. (#2943)
  • A bug in pdal tile where the input spatial reference wasn't set on the output has been fixed. (#2976)
