Modules	Description
AddInfo	Inserts or updates ODM attributes by combining existing attributes and/or grid models.
Algebra	Provides a generic raster algebra calculator featuring mathematical, statistical and conditional operators.
Cell	Calculates statistical features of user defined attributes and stores them as raster models or rasterized point clouds.
Colorize
Contouring	Derives the contour of foreground objects of a raster model and exports the results as a polygon shape file.
Convolution	Performs convolutional filtering operations on a raster image.
DBH	Estimate the Diameter at Breast Height (DBH) based on 3D point cloud data (ODM).
DSM	Calculates a land cover dependent DSM raster model based on the approach of Hollaus et. al. (2010).
DTM	Calculates a high quality Digital Terrain Model in hybrid grid structure (i.e. regular grid + structure lines).
EchoRatio	Derives and stores the echo ratio (ER) attribute for points of an OPALS data manager.
Export	Exports vector data stored in an OPALS data manager (ODM) in various data formats.
Grid	Derives a 2.5D digital elevation models (DEM) in regular grid structure using simple interpolation techniques.
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).
Import	Loads vector and raster data into an ODM for subsequent use in modules dealing with point cloud and line related data.
Info	Extracts and reports header information of a vector or raster file (ODM, GDAL).
ModelFromAxis
Morph	Applies morphological operations (opening, closing, erosion, dilation) on raster datasets.
Normals	Estimates local surface normal vectors for each point of a specific point cloud (ODM).
PointStats	Derives and stores statistical parameters describing the local distribution of a point attribute for each point of an ODM.
Rasterize	Performs vector-to-raster conversion for all types of simple feature geometries (points, lines, polygons).
RoadStats
Shade	Derives shaded relief raster maps (geo-coded hill shading) of DEM grids.
StatFilter	Performs statistical filtering of raster datasets with a sliding kernel of arbitrary shape and size.
TIN	Creates a TIN surface from ODM vector data based on a 2D constrained Delaunay triangulation.
Translate	Performs format conversion for vector data files with additional read support of GDAL rasters.
Vectorize	Performs raster-to-vector conversion and exports polyline geometries.
View	Provides an interactive 3d viewer for points (including arbitrary attributes) and lines.
ZColor	Derives color coded visualizations of grid models and stores them as geo-coded raster images.
