Alsproc Development

Structure

Subversion

Alsproc can be found in subversion under tools/alsproc. Obtain a copy with svn checkout.

svn checkout http://rsg.pml.ac.uk/intranet/svnroots/arsf-internal/trunk/tools/alsproc

You can make and manage your changes in this checkout. When you've tested it and you're happy, you may need to advance the version number. Edit the Makefile in src/, and find the line which says vers=x.x.x and advance it as you need.

# VERSION NUMBER
vers=0.0.9

When you're satisfied, commit the changes.

svn commit

And finally, tag the branch version if you advanced the version number.

svn cp http://rsg.pml.ac.uk/intranet/svnroots/arsf-internal/trunk/tools/alsproc http://rsg.pml.ac.uk/intranet/svnroots/arsf-internal/tags/alsproc-0.0.9 -m "tagging new version of alsproc"

Installation in ARSF

Current policy is to install in the home directory of the arsf user, as this asserts that all users across the department are using the same and current version of alsproc. Enter usr/opt/alsproc and check out the version you wish to build, check out the repository, compile it, and install it locally using the purpose-built Makefile rule: arsf_install.

cd ~arsf/usr/opt/alsproc
svn checkout http://rsg.pml.ac.uk/intranet/svnroots/arsf-internal/tags/alsproc-0.0.9
cd alsproc-0.0.9/src
make
make arsf_install

To Do

• Analysis and refinement of accuracy of individual points (ongoing)
• Geotagging las files (partially done)
• Better verification of proj4 strings
• Better verbose mode, current verbose mode is more like debug mode
• Better mechanism for passing values into alsproc
• More reliable detection of test flightlines or verification of current methods
• scn_info is very slow for what it does, it should be able to skip unneeded data
• las12_las output module is very inter-dependant on the calling script, it should ideally be fixed or replaced
