rlas v1.3.6

• 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

• 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

• 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

• 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.

rlas v1.3.1 (Release date: 2019-02-08)

• Fix: valgrind - Conditionnal jump on uninitialized value (consequentless for users)
• Fix: valgrind - Invalid read of size 2

• New: introduction of a set of 5+ functions to modify a header easily repecting LAS specifications
• Fix: #26 segfault in read.las when using an inappropriated filter such as -keep_class 123.

rlas v1.2.9 (Release date: 2018-10-26)

• New: write.las writes the epsg code in the header.

rlas v1.2.6 (Release date: 2018-08-20)

• Change: check_data now check the adequation between the ReturnNumberand the NumberOfReturns
• Fix: las format 7 was supported at the C++ level when reading a file but an old test still throw an error at the R level stating that this format was not supported.
• Fix: several compilation warnings on CRAN
• Change: readlasdata and readlasheader were definitively removed.

rlas v1.2.4 (Release date: 2018-06-10)

• Reupload on CRAN after being removed.

rlas v1.2.3 (Release date: 2018-05-17)

• New: Read the classification flags in fields Synthetic_flag, Keypoint_flag and Withheld_flag.
• Fix: point in polygon includes the points that define the polygon.
• Fix: [#21] writing a vector that contains only NAs in extra bytes
• Fix: additional warnings on CRAN with gcc 8+
• Fix: [#19] additional errors on CRAN with valgrind

• New: enables the support of files with point data formats 6, 7 and 8 in read mode.
• New: enables the support of extra bytes attributes in write mode.
• New: function read.las that replaces readlasdata, which is now deprecated. The selection of the field to be loaded is made easier by use of string syntax instead of multiple logical parameters.
• New: function read.lasheader that replaces readlasheader, which is now deprecated. This change was made only for naming consistency.
• New: functions header_* that allows the user to make valid headers and thus properly write the las files.

• New: function writelax for writing LAX files.
• New: function readlasdata enable for reading several files.
• Fix: the las files were read twice every time. lasdatareader is twice as fast since it reads files only once
