Rigels RiWORLD 6.1: Advanced Software for Intelligent Point Cloud Processing
Rigels RiWORLD 6.1 is a professional software suite dedicated to the processing, classification, and modeling of massive 3D point clouds acquired from airborne LiDAR, terrestrial laser scanning, and photogrammetry. It provides geospatial professionals, surveyors, and mapping agencies with powerful tools to automatically filter raw point data, extract meaningful features, and generate high-precision digital terrain models (DTMs) and 3D city models for urban planning, forestry, and infrastructure management.
Core Function: Transforming Raw Points into Intelligent 3D Data
The software’s primary function is to apply sophisticated algorithms to automatically classify billions of LiDAR points into standard categories (Ground, Vegetation, Buildings, Power Lines, etc.) and then use these classified points to create accurate vector and surface models. This automates the most labor-intensive step in the point cloud workflow.
Key Processing Workflows & Features:
1. Automatic Point Cloud Classification
-
Intelligent Filtering & Classification: Uses advanced algorithms to automatically separate ground points from above-ground objects (buildings, trees, vehicles). Further classifies points into predefined categories relevant to the project.
-
Interactive Editing Tools: Provides manual tools to review, correct, and refine the automatic classification results for maximum accuracy.
2. Terrain & Surface Model Generation
-
Digital Terrain Model (DTM) Creation: Generates a “bare-earth” terrain model from the classified ground points, essential for hydrological modeling, contour generation, and engineering design.
-
Digital Surface Model (DSM) & Normalized DSM (nDSM): Creates models representing the top surface of all objects and a height-normalized model useful for vegetation and building height analysis.
3. 3D Feature Extraction & Modeling
-
3D Building Model Reconstruction: Automatically extracts building footprints and can reconstruct 3D roof shapes and wall surfaces to create detailed 3D city models (Level of Detail 2 – LoD2).
-
Linear Feature Extraction: Can identify and model linear features like power lines, guardrails, and road edges.
4. Data Management & Export
-
Handles Massive Datasets: Efficiently processes and visualizes very large point cloud projects.
-
Format Support & Export: Supports major point cloud formats (LAS, LAZ) and exports classified points, DTMs/DSMs, and vector features to CAD, GIS, and other modeling software.
