rlas v1.8.2

New:read.las has a progress bar
New:read.las checks user interruption

rlas v1.8.1

Fix: can read file with multiple extra bytes definitions
Fix CRAN: Found non-API call to R: ‘DATAPTR’ for altrep
Removed aboost header still included in the code.
Functionstream.las exposed to users

rlas v1.8.0

Internal changes to appease CRAN: remove dependency toboost

rlas v1.7.0

support of Text Area Description#64
header_create() now take into accountScannerChannel
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_tinstead of[unsigned] long long andPRI[u|d]64to print[u]int64_t. This solves new warnings fromgcc-8 on Windows with%lld.

rlas v1.6.2

Fix compilation with g++-12 thanks to Dirk Eddelbuettel#57
Replacesprintf withsnprintf

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 ofnon populated attributes. For exampleUserData is usuallypopulated with zeros (not populated). Yet it takes 32 bits per point tostore each 0. It now uses 644 bits no matter the number of points if itis not populated. This optimization is automatically applied to eachattribute that contain a single repeated value. This enables to saveapproximately 30 to 40% of memory usage depending on the number ofnon-populated attributes.

rlas v1.5.3

Fix gcc-asan AddressSanitizer: global-buffer-overflow on CRAN whenreading las/laz with extrabytes attributes.
Fix warning: array subscript 32 is outside array bounds of ‘constchar [2]’ [-Warray-bounds]

rlas v1.5.2

Fix gcc-asan AddressSanitizer: global-buffer-overflow on CRAN whenreading 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 isnot null-terminated (fix#53)
Fix: value -128 can be read inScanAngleRank attribute.The value -128 previously triggered a false positive error (fix#54)
Fix:header_update() now populates theNumber of points by return with 0 in absence ofReturnNumber

rlas v1.5.0 (Release date:2021-06-02)

New: Full waveform support (still experimental and incomplete).read.las() can read full waveform butwrite.las() can’t write yet. The current read mode readsraw data without interpretation. A functionfwf_interpretation() can parse the raw data into somethingmore manageable by users. Everything is experimental and prone tomodification. For example we might change our mind and read interpretedwaveform instead of raw data in the future. The format of the output offwf_interpretation() may also change if we find that thiscurrent design is not relevant. In short the FWF support is not matureyet and we plan to provide a mature and stable API in v1.6.0.
Misc: removedLazyData inDESCRIPTION
Misc: UpdateDescription inDESCRIPTION toinclude format 1.4 in reading capabilities.
Enhance:header_create() creates a v1.4 header if thepoint source format is detected to be 6 or more
Enhance:header_create() usesfloor(min(X|Y|Z)) instead ofmin(X|Y|Z) asoffsets.
Enhance:header_create() infers the scale factor fromthe data instead of setting hard coded value 0.01

Fix: build failure with GCC 4.x
Fix: gcc-asan signed integer overflow.
Fix: when reading a non supported extra bytes attribute rlas used toprint 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 variablelength 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: usetinytest instead oftestthat

rlas v1.3.7 (Release date:2020-11-11)

Fix#48.header_set_epsg() incorrectly set the epsg code when thekey 3072 is missing but the VLR is not empty

rlas v1.3.6 (Release date:2020-06-02)

Fix: The functionis_valid_ReturnNumber() wronglytriggered errors when checking if the ReturnNumber attribute is correct.It missed errors for LAS < 1.4 and triggered wrong errors for LAS 1.4prf > 6.#45
Fix: The functionis_empty_point_cloud() did notactually test what it was expected to test.
Fix:is_valid_scalefactors() does not trigger anyreport for very fine scale factors such as 0.000001 that is a validscale of long/lat coordinates.
Fix:is_valid_returnnumber() does not complain forReturnNumber = 0. This is valid but not compliant to the specs.
Fix: formats 5, 7 and 10 were missing in the list of formats validfor storing RGB
Fix: format 10 was missing in the list of formats valid for storingNIR
Fix: more tests and fixes relative to asprs specification

rlas v1.3.5 (Release date:2020-02-04)

Change: defunc deprecated functionscheck_data,check_header andcheck_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 notcompliant with the specs (#44).
New: functionis_compliant_ScanAngle() to check thecompliance 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 functiontabulate() instead of home madeC++ code to count the return numbers.

Fix:#33 itis now allowed to writeScanAngleRank above 90 degrees butnot above 127 degrees.

Fix:#35Erreur reading a specific laz file. The actual problem is unknown. Thishas been fixed by updatingLASlib
Fix:#36Classification was zeroed when writing LAS1.4 prf 6. The actual problemis not known. This has been fixed by updatingLASlib
Fix:ScanAngle was rounded to integer for LAS 1.4 prf>= 6 before to be written. With the 0.006 factor conversion this leadto 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 touuid has been removed.
