Package opalsCity

The package opalsCity contains modules dealing with building and city modelling. Some of the modules require a Digital Terrain Model (DTM) and/or Digital Surface Model (DSM). For more details concerning the derivation of surface models within OPALS, pleaser refer to package opalsSurface.

opalsCity is not yet available.

Scripts and Modules of Package opalsCity
Modules Description
Contouring Derives the contour of foreground objects of a raster model and exports the results as a polygon shape file.
Export Exports vector data stored in an OPALS data manager (ODM) in various data formats.
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).
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).
Rasterize Performs vector-to-raster conversion for all types of simple feature geometries (points, lines, polygons).
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.
