<p style="margin-bottom: 0cm">Dear all,</p>
<p style="margin-bottom: 0cm"><br>
</p>
<p style="margin-bottom: 0cm">Today I uploaded a new GRASS 7 addon to SVN.</p>
<p style="margin-bottom: 0cm">The Python-script „v.lidar.mcc“ aims at removing vegetation returns from LiDAR point-clouds. It is a modified implementation if Evans & Hudak`s (2007) multiscale curvature classification (mcc) algorith.</p>
<p style="margin-bottom: 0cm">Compared to the original, the GRASS module has a few more options (useer can define also spline steps, number of scale domains, and convergence threshold). I am not sure if terrain interpolation method in v.outlier (which v.lidar.mcc
uses) does match exactly the thin-plate interpolation that Evans & Hudak used. </p>
<p style="margin-bottom: 0cm"><br>
</p>
<p style="margin-bottom: 0cm">When I find the time I will compare results and performance to the original mcc-tool... I hope the manual is understandable and I would be happy about feedback...</p>

<p style="margin-bottom: 0cm">Cheers</p>
