Version

Version 2.1

• Released: 8 January 2013
• Download MCC-LIDAR-setup.exe
  • Fixed an issue with the program not recording lower left XY coordinates properly in output ascii grid files.
  • Fixed the bug where the program crashed with larger scale and threshold parameters (ticket [#36])

Version 2.0

• Released: 8 January 2013
• Download MCC-LIDAR-setup.exe
  • Code updated to conform with the latest version 1.7.0 of libLAS library and OSGeo4W distribution.
  • The code now compiles against the recent version 1.51.0 of the boost library (ticket [#46]).

Version 1.0

Final Release

• Released: 1 July 2011
• Download MCC-LIDAR-setup.exe
  • The header in the *.las output file now indicates that the file was generated by MCC-LIDAR
    (ticket [#20]).
  • When too many output files are specified, the program now lists them in the error message
    (ticket [#29]).
  • Fixed the bug where the program crashed while searching for points with the same X,Y
    coordinates (ticket [#45]).
  • Added short options for --help (-h) and --version (-v) (ticket [#7]).

Known Issues

• Sometimes the program will crash on Windows with large scale and threshold parameters (ticket [#36]). A workaround is available.

Release Candidate 4

• Released: 13 May 2011
• Download MCC-LIDAR-1.0rc4-setup.exe
  • Fixed the bug where the program crashed with singular matrix error while interpolating the
    ground surface for the *.asc output file (ticket [#38]).
  • Modified the program so that it now assigns the classification value 1 (for "unclassified")
    to all the points that it doesn't classify as ground (ticket [#43]).

Release Candidate 3

• Released: 14 December 2010
• Download MCC-LIDAR-1.0rc3-setup.exe
  • Discovered that the wrong QA release was distributed as release candidate 2. To help with
    managing releases, the output from the --version option was modified to include the revision
    number of the source code used to build a particular release (ticket [#37]).

Release Candidate 2

• Released: 9 December 2010
• Download MCC-LIDAR-1.0rc2-setup.exe
  • Modified the program to handle duplicate points, i.e, points with the same X,Y,Z coordinates,
    in the input file (tickets [#34], [#35]).
  • Modified how the program responds to a singular matrix error during surface interpolation.
    Instead of reporting the error and stopping, the program now adds a nearby point to the set
    of points for a spline calculation and restarts the calculation. It repeats this process
    of adding a point and restarting the spline calculation until the singular matrix error
    doesn't occur (ticket [#30]).

Release Candidate 1

• Released: 8 August 2010
• Download MCC-LIDAR-1.0rc1-setup.exe
  • Changed the surface interpolation so that every cell in ground-surface output files has a value
    (ticket [#27]).
  • The X,Y coordinates of the extent of the input LAS file are reported in floating-point numeric
    format instead of exponential format (ticket [#2]).

Beta 5 Release

• Released: 9 July 2010
• Download MCC-LIDAR-1.0b5-setup.exe
  • Fixed a bug which was causing too many NODATA cells in the ground-surface output file (ticket [#16]).
  • Changed the percentage that determines convergence for each of the scale domains. Previously, they
    all used 0.1%; now a sequence of decreasing percentages (1%, 0.1%, 0.01%) is used to reduce the
    program's run time (ticket [#24]).

Beta 4 Release

• Released: 7 June 2010
• Download MCC-LIDAR-1.0b4-setup.exe
  • Added more checks on input parameters:
    • Post spacing must be positive (ticket [#21]).
    • Curvature threshold must be 0 or positive (ticket [#22]).
  • Fixed a bug where a thin plate spline calculation would fail because the spline's 3 control points
    lie in a vertical plane (ticket [#19]).

Beta 3 Release

• Released: 4 May 2010
• Download MCC-LIDAR-1.0b3-setup.exe
  • Added a new type of output file: a CSV (comma separated values) file with ground points (ticket [#14]).
  • Increased the limit of passes per scale domain from 20 to 100, in order to increase convergence with large datasets (ticket [#13]).
  • Improved the error message that user sees when insufficient memory (ticket [#10]).

Beta 2 Release

• Released: 3 April 2010
• Download MCC-LIDAR-1.0b2-setup.exe
  • Fixed bugs where program crashed during pass 1 of scale domain 1 (tickets [#4], [#8]).
  • Fixed build errors with GCC 4.3.4 on Linux (ticket [#5]).
  • Fixed typo in help message (ticket [#1]).
  • Added --nonground-pts option to create output files with the points classified as non-ground by each pass.
  • Added --surfaces option to create ASCII Grid files with the raster surfaces interpolated by each pass.

Beta 1 Release

• Released: 20 November 2009
