GridFeature	Derives feature models (slope, curvature, roughness, etc.) from grid models based on the local grid neighbourhood defined by a kernel.
Histo	Derives histograms and descriptive statistics (min, max, mean, r.m.s, etc.) for ODM or grid/raster data sets and stores the results graphically (SVG) and numerically (XML).
ICP	Performs orientation (co-registration) of multiple point cloud datasets using the Iterative Closest Point algorithm.
Import	Loads vector and raster data into an ODM for subsequent use in modules dealing with point cloud and line related data.
