Changes of Note

GDAL VSI Support

@normanb added support for GDAL VSI in #4647. It is now possible to use VSI to control access to remote content. Any /vsi-prefixed file path will go through GDAL's VSI layer.

pdal info \ /vsicurl/https://github.com/PDAL/data/raw/refs/heads/main/autzen/autzen-classified.copc.laz \ --readers.copc.resolution=1000

FileSpec Support

@trns1997 and @ibell13 added support for "FileSpec" in #4633 and #4625. FileSpec allows you to add a JSON node with filename, headers, and query members to control access to remote content. FileSpec uses non-VSI remote file access, so any http:// or s3:// -prefixed URLs will use this access system.

[ { "type": "readers.copc", "filename": { "path": "https://some/remote/file.laz", "headers": { "headerkey": "headerval" }, "query": { "querykey": "queryval" } } } ]

nlohmann Public API removal

https://github.com/nlohmann/json unfortunately changed its primary data type and broke the usage pattern that PDAL and others had been using to forward declare and use it. Initially reported by @jgrocha in #4706, it was decided to completely remove nlohmann from PDAL's public API to prevent downstream PDAL users compilation from breaking in the future when they are also using nlohmann in their APIs. See (#4721, #4722, #4723, #4724, #4725, #4727, #4728, #4731) for details.

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.

pdal - 2.1.0

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.

pdal - 1.9.0

Important Functionality Note

The meaning of the precision option for filters.hexbin for WKT output has changed from "digits after the decimal point" to "total digits of precision". If you need text output as precise as possible, you should set the value to 17. This change is most obvious when using the boundary option with the pdal info command.

Changes of Note

Changes of Note

PCL --visualize capability of the pdal command line application has been removed.
writer.derivative has been removed. Use gdaldem for faster and more featureful equivalent functionality.
GeoTIFF and Proj.4 are now required dependencies.
writers.p2g has been removed. It was replaced by writers.gdal in 1.4, but the P2G writer was essentially unmaintained and we will be using the GDAL one going forward.

Support was added for the recently added cartesian coordinate in BPF files.
writers.p2g now uses the InCoreInterp method of the points2grid code. This uses more memory but runs faster and doesn't crash.
The application now provides better error feedback on command-line errors by indicating the invoked kernel when an error is detected.
PDAL now searches by default in the following locations for plugins: "." "./lib", "../lib", "./bin", "../bin". Use PDAL_DRIVER_PATH to explicitly override the plugin search location.
Vector-based command-line arguments now accept default values in the API.
JSON parsing errors of pipeline files now provide more detailed messages.
Writers now add output filenames to metadata.
Stage names provided as input to other stages in pipelines can now be specified as strings or arrays of strings. The previous version required single input stage names to be placed in an array.
Added --smooth option to filters.hexbin to allow user control of boundary smoothing.

Bug fixes

Well-known text provided as a spatial reference isn't interpreted by GDAL unless necessary.
filters.hexbin now returns MULTIPOLYGON EMPTY when it is unable to compute a boundary.
Reading a not a number (nan) value from a text file now works properly.
The --compression option for writers.pcd has been fixed so that the writer actually compresses as requested.
The stage manager (and hence, pipelines) now properly recognizes the text reader as readers.text.
readers.text now detects the case when a dimension has been specified more than once in an input file.
Fixed a problem where filters.splitter could create cells larger than requested about the X and Y axes.
writers.nitf now errors if it attempts to write an FTITLE field that exceeds the allowable length.
If PDAL is build with LAZperf but without LASzip, the program now properly defaults to using LAZperf.
Fixed a problem where filters.sort could fail to properly order points depending on the implementation of the C++ sort algorithm.
Fixed a problem in pgpostgres readers and writers where a failure in a query could lead to a crash.

pdal - 1.3.0

Changes of Note: - Command line parsing has been reworked to cause invalid options to emit an error message. Stage options specified in pipelines and on the command line are handled similarly. - The dimension PlatformHeading has been renamed to Azimuth. When looking up a dimension by name, the string "platformheading" is still accepted and returns Azimuth. - Errors detected by GDAL are no longer thrown as exceptions. A log message is emitted instead. - Well-known dimensions are now added to PDAL by editing a JSON file, Dimension.json. - Linking with PDAL using CMake no longer requires explicit linking with curl, jsoncpp or arbiter libraries. - PDAL now searches for plugins in the following locations and order by default: ./lib, ../lib, ../bin, the location where PDAL was installed. - The '--debug' and '--verbose' options are no longer supported as stage options. The '--verbose' option is accepted on the PDAL command line. The '--debug' option is deprecated, and if specified on the command line is equivalent to '--verbose=3'. One can enable logging programmatically by calling setLog() on a PipelineManager or a specific stage. - pdal::Dimension types are now C++11 enumeration classes. The change may require editing any Stage implementations you might have and removing the extraneous ::Enum type specification.

Enhancements: - Pipelines can now be read directly from standard input. - Files can now be read from Amazon S3 buckets by providing an appropriate URL. - Many new filters have been added: filters.approximatecoplanar, filters.eigenvalues, filters.estimaterank, filters.hag, filters.normal, filters.outlier, filters.pmf, filters.sample. Most of these are algorithm extractions from the PCL library, with the hope of eliminating the need for PCL in some future PDAL release. - The PLY reader now loads dimensions that aren't predefined PDAL dimensions. - A '--driver' option has been added to allow a specific driver to be loaded for a file without regard to its extension. - The PDALDRIVERPATH environment variable now accepts a list of locations to search for drivers. - Beta release quality drivers improvements in readers.greyhound - Beta quality implementation of Mongus and Zalik ground filter - Experimental implementation of Pingel et al. ground filter - writers.pcd enhancements by Logan Byers (binary, compression) -- requires PCL - Docker images upgraded to Ubuntu Xenial - Cyclone PTS reader -- readers.pts - skewness, kurtosis, stddev, and variance added to filters.stats output - Python API now available https://pypi.python.org/pypi/pdal

Fixes: - A failure that may have resulted when using filters.hexbin to calculate density in the southern hemisphere has been corrected. - A failure to create the index file with 'pdal tindex' and GDAL 2.X has been fixed. - The '--tindex' option for the 'pdal tindex' command is now a positional option as specified in the documentation. - The icebridge reader now reads the X dimension as longitude and forces the value in the range (-180, 180]. It also properly uses the dimension Azimuth instead of ScanAngleRank. - An error in writers.pgpointcloud where it ignored SQL to be run at the end of the stage has been fixed. - An error that might incorrectly write values stored internally as bytes when written as a different data type has been fixed. - A problem where 'pdal info' wouldn't properly report dimension names not predefined by PDAL has been fixed. - A bug in filters.crop that wouldn't properly transform coordinates when provided the '--a_srs' option has been fixed.

1.2.0:

Changes of Note: - The GEOS library is now required to build PDAL. In earlier versions it was an optional component. - Boost is no longer a required component. Unless you are building plugins that require boost (notably PCL and Geowave), you no longer will need boost installed on your system to build or run PDAL. - PDAL now builds on Microsoft Visual Studio 2015. - The PipelineReader class has been removed and its functionality has been merged into PipelineManager. - Plugin libraries now support Linux versioning. - Naming changes have been made to allow packaging with the Debian release. - filters.height now uses the dimension 'HeightAboveGround' instead of a dimension named 'Height' to be compatible with the filters.heightaboveground. - Option names no longer contain lowercase characters. - PDAL now works with GDAL version 1.9 and later. - Stages created with the StageFactory are now owned by the factory. - filters.dartthrowing has been renamed filters.dartsample - 'pipeline-serialization' now produces JSON output instead of XML.

Enhancements: - Pipelines may now be specified using a JSON syntax. XML syntax is still supported but users should switch to JSON when possible as the XML support will be removed in a future version. - PDAL now can be built into a Docker container. - Many stages now support "streaming," which allows control of the number of points stored in memory during processing. See Stage::execute(StreamPointTable&) for more information. - A basic text reader has been added. - Added support for the dimension 'ClassFlags' in readers.las. - The derivative writer can now produce output for multiple primitive types with a single execution. - 'pdal info' now provides bounding box output instead of a more refined boundary when the hexbin plugin isn't found. - Added 'pdal density' to provide a command-line interface to the filters.hexbin density calcuations. - The icebridge reader can now load an associated metadata file. The reader also now marks the associated coordinate system as WGS84. - The stats filter now emits bounding box information in native and WGS84 projections. - PDAL command-line programs now (generally) check their argument lists for correctness and report syntax errors. - 'pdal info' now provides spatial reference attributes in addition to the actual well-known text. - Geometry can now be specified as GeoJSON as well as well-known-text in most contexts. Geometry optionally provides Z-dimension output. - Stage and plugin creation is now thread-safe (NOTE: Most of PDAL is NOT thread-safe, so tread carefully). - Many, many documentation enhancements.

Fixes: - A bug in generating PCIDs when with multiple simultaneous PDAL executions to the same Postgres database has been fixed. - Fixed a bug in generated SQL delete statements when certain table names were used in the writers.postgres driver. - Properly escape quotes when generating JSON output. - Fix an off-by-one error when writing data with the derivative writer that could lead to a crash. - Fixed a dependency error during builds that could lead to a failure to properly load Python extensions on Linux. - Fixed a bug where passing certain options to 'pdal info' could be handled in ambiguous ways. - Fixed bugs in the reading of raster data using readers.gdal. - Fixed population of the AIMIDB and ACFTB attributes in writers.nitf. - Corrected the parsing of some dimension names in filters.colorization. - Fixed a potential truncation in the GlobalEncoding dimension of readers.las.
