"The Latest Version"

Version 3.60 is the latest version of FUSION.

Version 3.60 includes two new programs: AreaProcessor and TreeSeg. Refer the the FUSION manual for details for both and specific instructions for using AreaProcessor to create processing workflows for large areas.

This version also introduces some configuration information specific to your computer regarding the use of GDAL utilities with the workflows created by AreaProcessor. Be sure to look at the APScripts\ComputerSpecific folder in the FUSION install folder to make sure that the information in GDALconfig.bat matches your system.

Version 3.40 added support for compressed LAS data files by linking to Martin Isenburg's LASzip.dll. To take advantage of this capability, you will also need to install LAStools and manually copy the LASzip.dll file into FUSION's install folder.

LAStools can be found here: http://rapidlasso.com/lastools/ or here: http://lastools.org/

If you have an earlier version of FUSION, you should upgrade to take advantage of several new features and bug fixes.

To upgrade from previous version, first remove the old version using the "Add/remove programs" option in the Windows control panel.  Then simply install the new version into the same folder as the previous version.  Existing project and data files should not be affected.
