LiDAR Data Processing

Transforming Raw LiDAR Scans into Precise Spatial Intelligence

At Cartospatial Technologies, our LiDAR Data Processing services convert massive volumes of raw point cloud data into clean, classified, and geospatially accurate products. With advanced software and expert workflows, we provide filtered, feature-rich datasets essential for design, analysis, and decision-making across industries.


Key Features of Our LiDAR Data Processing

  • ✅ Raw Data Cleaning & Noise Removal
    • Filtering out atmospheric interference, moving objects, and errors
    • Ensures high-quality point clouds free of outliers and artifacts
  • ✅ Point Cloud Classification
    • Automated and manual classification of ground, vegetation, buildings, and water bodies
    • Custom class definitions per project needs
  • ✅ Georeferencing & Coordinate System Alignment
    • Precise alignment with GPS and control points
    • Support for any projection system (WGS84, UTM, local grids)
  • ✅ DTM & DSM Generation
    • Separation of terrain from surface features
    • Creation of Digital Terrain Models (DTM) and Digital Surface Models (DSM)
  • ✅ Feature Extraction & Vectorization
    • Automated extraction of roads, powerlines, buildings, trees, and other features
    • Conversion of point cloud data into vector formats (lines, polygons)
  • ✅ Quality Assurance & Accuracy Validation
    • Cross-checks against ground control points (GCPs)
    • Statistical error reporting and completeness analysis
  • ✅ Data Compression & Optimization
    • File size reduction without quality loss for easy handling
