Lidar Data Processing

GIS Data Processing

Preprocessing

• Radiometric correction (adjusting sensor noise, calibration)

• Geometric correction (alignment with map coordinates)

• Noise removal (e.g., atmospheric correction)

• Resampling and re-projection

Image Processing

• Image enhancement (contrast stretching, filtering)

• Image fusion (combining different sensor data)

• Pan-sharpening (enhancing spatial resolution)

Data Analysis and Interpretation

• Classification (supervised/unsupervised)

• Change detection (monitoring changes over time)

• Object detection and feature extraction

• NDVI (vegetation), NDBI (built-up), NDWI (water)

Data Preprocessing

• Geotagging: Attach GPS data to images

• Image quality check: Remove blurred or over/underexposed images

• Ground Control Points (GCPs) (if high accuracy is needed)

Generate Output:

• Orthomosaic (georeferenced 2D image)

• Digital Surface Model (DSM)

• Digital Terrain Model (DTM)

• 3D point clouds

• Mesh models (3D visualization)

• Calculate volumes (e.g., stockpiles, excavation sites)

• Measure surface areas and elevation profiles

Visualization & Reporting

• Generate maps, 3D models, elevation profiles

• Share results through web maps or PDF reports

Processing & Classification

• Differential GPS correction (PPK/RTK) for higher accuracy

• Classification: Ground (terrain), Non-ground (vegetation, buildings, power lines)

Data Products Generation

• Digital Terrain Model (DTM)

• Digital Surface Model (DSM)

• Contours

• 3D visualization: Point clouds, mesh models, contours

Feature Extraction

• Extract linear and polygonal features (e.g., roads, buildings, power lines)

• Tree height and density estimation

• Volume calculations (e.g., stockpiles, cut/fill analysis)

Change Detection

• Compare LiDAR datasets from different times

• Identify changes in terrain, vegetation, infrastructure

Data Import and Quality Control

• Import spatial data (vector: points, lines, polygons; raster: imagery, DEMs)

• GIS Data conversions (KML, GeoTIFF, ASCII Grid, CAD etc.)

• Metadata tagging and documentation

• Remove duplicates and topological errors (gaps, overlaps, slivers)

• Fix attribute errors and missing data

GIS Analysis

• Overlay analysis: Intersect, union, clip, erase

• Proximity analysis: Buffers, nearest neighbor, distance calculations

• Terrain analysis (using DEMs): Slope, aspect, hillshade, watershed

• Map algebra: NDVI, land cover classification

• Raster-to-vector and vector-to-raster conversions

Map Creation and Visualization

• Thematic maps (land use, population density, risk zones)

• Cartographic design: symbols, legends, scale, north arrow, layout

• 3D scenes and fly-through animations

Training and Support

• Software training (QGIS, ArcGIS, Pix4D etc.)

• Technical support and consulting
