TERRAIN ANALYSIS
& MAPPING
Grace GIS delivers high-accuracy terrain analysis and mapping services using LiDAR and elevation data to support planning, engineering, hydrology, and environmental assessment. Our terrain products provide a reliable foundation for understanding landform behaviour, water movement, and development constraints.

What We Do
• LiDAR processing and elevation modelling
• Digital Terrain Models (DTM) and Digital Surface Models (DSM)
• Contour generation (high-resolution and engineering-grade)
• Slope, aspect, and landform analysis
• Flow direction and accumulation modelling
• Terrain correction and QA
• Integration with hydrological and infrastructure models
Deliverables
Clients receive:
• Digital Terrain Models (DTM) and Surface Models (DSM)
• Contours at required intervals
• Terrain derivatives (slope, aspect, flow paths)
• GIS-ready datasets and map outputs
• Metadata and quality documentation
If your project requires accurate terrain data as a foundation for analysis or design, Grace Detailed GIS Services can help.
