PDAL/PDAL: 2.4.0RC1

Published March 18, 2022 | Version 2.4.0RC1

Software Open

Changes of Note

A compiler that supports C++17 is now required to build PDAL or include PDAL headers in your code.
The PDAL_STATIC_BUILD cmake option has been removed. We do not support building PDAL as a static library, though it may work.
The behavior of readers.ept when specifying both bounds and polygon options has changed such that a point must pass both the filters independently in order to be accepted. (#3506)
readers.ept will now ignore the spatial reference on a clip region if the point source has no spatial reference. This behavior is consistent with filters.crop. (#3580)
readers.las and writers.las no longer support the laszip library. Both stages now use the lazperf library, which is embedded into the PDAL library. The compression option is still accepted in readers.las, but is ignored. The compression option on writers.las still accepts the LASZIP and LAZPERF , but those values are treated the same as TRUE.
PDAL now builds on MinGW, though future support depends on community contributions.
Source code supporting las and ept has been moved to a private namespace.

New Stages

readers.copc and writers.copc have been added to support reading and writing of COPC files.
readers.smrmsg was added to read from post-processed MMS accuracy files to be used with SBET data.

Enhancements

The performance of filters.litree has been improved. (#3518)
Support for time query/storage in readers.tiledb and writers.tiledb has been added. (#3495)
Added various remote access support (AWS Fargate, AWS session token support, Azure SAS token support). (#3496)
An error is now reported when reading a pipeline with multiple leaf nodes.
Support for beam direction and origin in readers.rxp has been added. (#3565)
Add a cmake macro PDAL_CREATE_PLUGIN that may simplify the creation of some PDAL plugin stages. (#3588)
writers.null is now streamable. (#3591)
Added support for multiple output files in writers.ply (#3617 - Thanks @longhuan2018)
filters.csf now permits selective output of debugging/analysis files. (#3488)
Comments in JSON input files (pipelines) are now supported. (#3670)
Added support in writers.las for creating VLRs from metadata. (#3683)
Added query support origin query in version 1.1 of EPT. (#3505)
