2.4.1
Changes of Note
writers.copc now sorts chunks by GPStime, allowing better compression.
Various warnings for newer compilers have been eliminated.
Enhancements
Errors from the geotiff library are now directed to the console
(standard error).
readers.bpf now adds a count of the number of points to metadata.
The pdal info command now always writes a GeoJSON metadata entry of
the area boundary called boundary_json.
2.4.0
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)
2.3.0
Changes of Note
GDAL version 3 is now required. (#3428)
readers.tiledb now defaults to unordered reads. (#3267)
readers.tiledb now supports Hilbert ordering. (#3345)
writers.pcd now writes 32-bit floating point for X, Y and Z by
default. (#3286)
The GDAL error handler is redirected to its destination when PDAL
logging stops. (#3244)
New Command
Added pdal eval to print a classification report from two input
point clouds. (#3346)
Added pdal chamfer to calculate the chamfer distance, a metric used
to quantify the similarity of two point clouds by evaluating the mean
square distance of nearest neighbor correspondences between clouds.
New Stages
filters.gpstimeconvert allows conversion between the various GPS
time standards.
filters.teaser uses the truncated least squares estimation and
semidefinite relaxation (TEASER) algorithm to create a rigid
transformation between two datasets.
readers.draco reads the Draco format.
writers.draco writes the Draco format.
filters.zsmooth sets a dimension to a value determined by nearby
points. (#3408)
Removed Stages
readers.oci
writers.oci
Enhancements
pdal pipeline and pdal translate now support a --dims option that
allows the stored dimensions to be easily controlled. (#3310)
readers.las now reports and terminates on some previously undetected
LAS file errors. (#3226)
Added override_srs and default_srs options to readers.gdal to allow
a raster with only NODATA to have an SRS. (#3271)
Support was added for MSVC 2019. (#3292)
Added text output of GeoTIFF keys to metadata when reading LAS
data. (#3299)
Added programmatic support to merge summary statistics. (#3321)
Extra dimension names in a LAS file containing characters deemed
illegal by PDAL are now converted by default to legal PDAL dimension
names. (#3325)
The sample filter is now streamable. (#3275)
Added the --error_on_failure option to filters.reprojection to allow
the program to terminate if a projection operation fails. (#3316)
Added the --start option to readers.las to allow skipping some number
of points. (#3313)
Set the `ACCEPT_ENCODING' curl option to enable automatic
decompression of HTTP replies.
Improve error messages for LAS where a specified point format is
not permitted. (#3324)
Add the --where option to all writers. (#3319)
Added a --nosrs option to readers.las to avoid reading the SRS
information. (#3441)
Improved performance of readers.ept in stream mode. (#3331)
pdal-lib: fix build on NetBSD
geography: Replace RMD160 checksums with BLAKE2s checksums All checksums have been double-checked against existing RMD160 and SHA512 hashes
geography: Remove SHA1 hashes for distfiles
geography/pdal-lib: new package for PDAL PDAL is Point Data Abstraction Library. It is a C/C++ open source library and applications for translating and processing point cloud data. It is not limited to LiDAR data, although the focus and impetus for many of the tools in the library have their origins in LiDAR.
