Bare Earth Terrain Modelling

DTM Classification

LiDAR Ground Extraction

Separate terrain from vegetation, buildings, and surface clutter

GIS-Ready Elevation Products

Reliable terrain layers for design, planning, and analysis

Bare Earth / Digital Terrain Model

Clean terrain classification from complex LiDAR point clouds.

Airborne and mobile LiDAR pulses can return from roofs, vegetation, utility assets, and the earth surface beneath them. DTM classification identifies the reliable ground returns inside that point cloud and converts them into bare-earth terrain products for engineering, GIS, environmental analysis, and infrastructure planning.

Terrain Extraction Workflow

From raw returns to smooth, quality-controlled DTM deliverables.

We classify point-cloud returns into ground, vegetation, buildings, powerline objects, water, and other surface classes, then refine the ground layer with manual quality checks. The final output can support contours, breaklines, hydrology modelling, flood studies, corridor design, route planning, and GIS integration.

Bare-Earth Ground Class

Accurate separation of terrain points from buildings, vegetation, vehicles, and other above-ground features.

DTM and Contours

Terrain surfaces, contour-ready outputs, elevation grids, and terrain products for GIS and CAD workflows.

Hydrology Support

Terrain layers prepared for drainage review, flood modelling, watershed analysis, and water-flow studies.

Infrastructure Planning

Reliable ground models for roads, rail, utilities, corridors, land development, and engineering design.

GIS Integration

Structured outputs that combine with orthophotos, vector layers, cadastral data, and planning datasets.

Quality Assurance

Visual inspection, cross-section checks, noise cleanup, and delivery review for dependable elevation data.

3D Modelling and Meshing

Terrain intelligence for visualization, simulation, and project delivery.

DTM classification is the foundation for terrain meshes, 3D visualization, digital twins, simulation-ready environments, and map products that need the true ground surface rather than the top of buildings or canopy. Clean ground data helps teams design with confidence.
