rlas v1.8.0
- Internal changes to appease CRAN: remove dependency to boost
rlas v1.7.0
- support of Text Area Description #64
header_create() now take into account
ScannerChannel- Remove Rcpp.h and replace by R.h saves 2:30 min of compilation.
- support of COPC spatial indexed files
rlas v1.6.3
- Fix warnings with gcc-12
- C internals have been standardized to use
[u]int64_t
instead of [unsigned] long long and PRI[u|d]64
to print [u]int64_t. This solves new warnings from
gcc-8 on Windows with %lld.
rlas v1.6.2
- Fix compilation with g++-12 thanks to Dirk Eddelbuettel #57
- Replace
sprintf with snprintf
rlas v1.6.1
- Fix -Wempty-body on CRAN request
- Fix -Wformat on CRAN request
rlas v1.6.0
The ALTREP framework is now used to load compact representation of
non populated attributes. For example UserData is usually
populated with zeros (not populated). Yet it takes 32 bits per point to
store each 0. It now uses 644 bits no matter the number of points if it
is not populated. This optimization is automatically applied to each
attribute that contain a single repeated value. This enables to save
approximately 30 to 40% of memory usage depending on the number of
non-populated attributes.
rlas v1.5.3
- Fix gcc-asan AddressSanitizer: global-buffer-overflow on CRAN when
reading las/laz with extrabytes attributes.
- Fix warning: array subscript 32 is outside array bounds of ‘const
char [2]’ [-Warray-bounds]
rlas v1.5.2
- Fix gcc-asan AddressSanitizer: global-buffer-overflow on CRAN when
reading las/laz with extrabytes attributes.
rlas v1.5.1 (Release date:
2022-02-08)
- Fix: read of a 32 characters extra bytes description string that is
not null-terminated (fix #53)
- Fix: value -128 can be read in
ScanAngleRank attribute.
The value -128 previously triggered a false positive error (fix #54)
- Fix:
header_update() now populates the
Number of points by return with 0 in absence of
ReturnNumber
rlas v1.5.0 (Release date:
2021-06-02)
- New: Full waveform support (still experimental and incomplete).
read.las() can read full waveform but
write.las() can’t write yet. The current read mode reads
raw data without interpretation. A function
fwf_interpretation() can parse the raw data into something
more manageable by users. Everything is experimental and prone to
modification. For example we might change our mind and read interpreted
waveform instead of raw data in the future. The format of the output of
fwf_interpretation() may also change if we find that this
current design is not relevant. In short the FWF support is not mature
yet and we plan to provide a mature and stable API in v1.6.0.
- Misc: removed
LazyData in DESCRIPTION
- Misc: Update
Description in DESCRIPTION to
include format 1.4 in reading capabilities.
- Enhance:
header_create() creates a v1.4 header if the
point source format is detected to be 6 or more
- Enhance:
header_create() uses
floor(min(X|Y|Z)) instead of min(X|Y|Z) as
offsets.
- Enhance:
header_create() infers the scale factor from
the data instead of setting hard coded value 0.01
rlas v1.4.0 (Release date:
2021-03-23)
- Fix: build failure with GCC 4.x
- Fix: gcc-asan signed integer overflow.
- Fix: when reading a non supported extra bytes attribute rlas used to
print a warning message. It now throws a real warning.
- Fix: querying ROI using LAX files in LAS file > 2GB on Windows
(see #50)
- Fix: file creation day is now written (see #51)
- New:
read.lasheader() now reads the extended variable
length record (EVLR)
- New:
write.las() now writes all GeoKeyDirectoryTag +
GeoAsciiParamsTag + GeoDoubleParamsTag
- New:
write.las() can now write WKT OGC CS in EVLR
- Enhance: full update of LASlib (fix #43)
- Change: use
tinytest instead of
testthat

2021-01-11)
- Fix gcc-asan new-delete-type-mismatch error when reading las/laz
with lax files that appeared with C++14 and later standard.

rlas v1.3.7 (Release date:
2020-11-11)
- Fix #48.
header_set_epsg() incorrectly set the epsg code when the
key 3072 is missing but the VLR is not empty
rlas v1.3.6 (Release date:
2020-06-02)
- Fix: The function
is_valid_ReturnNumber() wrongly
triggered errors when checking if the ReturnNumber attribute is correct.
It missed errors for LAS < 1.4 and triggered wrong errors for LAS 1.4
prf > 6. #45
- Fix: The function
is_empty_point_cloud() did not
actually test what it was expected to test.
- Fix:
is_valid_scalefactors() does not trigger any
report for very fine scale factors such as 0.000001 that is a valid
scale of long/lat coordinates.
- Fix:
is_valid_returnnumber() does not complain for
ReturnNumber = 0. This is valid but not compliant to the specs.
- Fix: formats 5, 7 and 10 were missing in the list of formats valid
for storing RGB
- Fix: format 10 was missing in the list of formats valid for storing
NIR
- Fix: more tests and fixes relative to asprs specification
- New: new parameter transform to apply streaming transformations
- New: list of filters and transformations are available via
read.las(filter = "-h") and
read.las(transform = "-h")
- Enhancement: las specification tests now check for NAs
rlas v1.3.5 (Release date:
2020-02-04)
- Change: defunc deprecated functions
check_data,
check_header and check_data_vs_header.
- Fix:
is_valid_ScanAngle() triggers an error if |a| >
196.6 instead of 180. 196.6 is the maximum writable angle but is not
compliant with the specs (#44).
- New: function
is_compliant_ScanAngle() to check the
compliance of the Scan Angle.
rlas v1.3.4 (Release date:
2019-09-19)
- Fix: One Definition Rule (ODR) violation in LASzip (LTO issue)
- Note: use the function
tabulate() instead of home made
C++ code to count the return numbers.
rlas v1.3.3 (Release date:
2019-08-30)
- New: unlock reading
.ply files in read.las
and read.lasheader. This is an undocumented feature not
actually intended to be used. (#39).
- New: verbose option in
writelax().
- Fix: (#40)
in
read.las and read.lasheader modifications
in string encoding in R 3.5.0 generated issues with path containing
special characters. Native encoding is now enforced.
rlas v1.3.2 (Release date:
2019-04-26)
- Fix: #33 it
is now allowed to write
ScanAngleRank above 90 degrees but
not above 127 degrees.
- Fix: #34 fix
a misinterpretation of the LAS specification. Offset can be
negative.
- Fix: #35
Erreur reading a specific laz file. The actual problem is unknown. This
has been fixed by updating
LASlib
- Fix: #36
Classification was zeroed when writing LAS1.4 prf 6. The actual problem
is not known. This has been fixed by updating
LASlib
- Fix:
ScanAngle was rounded to integer for LAS 1.4 prf
>= 6 before to be written. With the 0.006 factor conversion this lead
to unrelated values when reading back a written file.
- Change:
header_create() does not generates random UUID.
The UUID is set to "00000000-0000-0000-0000-000000000000".
Dependence to uuid has been removed.
- Change: Dependancies to
sp, sf and
rgeos were no longer useful. rlas only depends
on data.table + Rcpp.

2018-08-20)
Change: check_data now checks the adequation between
the ReturnNumber and the
NumberOfReturns
Change: readlasdata and readlasheader

when reading a file but an old test still throw an error at the R level
stating that this format was not supported.

made only for naming consistency.
- New: functions
header_* that allows the user to make
