Slope Map Applications

Slope maps reveal terrain gradient—critical information for everything from drainage planning to solar farm siting. LiDAR-derived slope maps offer superior accuracy calculated from high-resolution Digital Terrain Models.

A slope map represents the rate of change in elevation across a terrain surface, typically expressed in degrees (0-90°) or percent rise. LiDAR-derived slope maps filter out vegetation and structures to show true terrain gradient.

Site grading analysis before construction. Identify areas exceeding specs (3% for parking lots, 2% for ADA compliance, up to 33% for embankments):
• Pre-construction site analysis
• Earthwork volume calculations
• Retaining wall requirements
• Road alignment optimization

Model water flow direction and accumulation:
• Watershed delineation
• Storm drain placement
• Flood-prone low-gradient areas
• Erosion risk mapping

Continuous slope monitoring for safety. Maintain pit wall angles within geotechnical limits (45-70°):
• Pit slope stability monitoring
• Haul road gradient compliance (8-12% max)
• Stockpile assessment
• Reclamation planning

Identify optimal panel placement. Ground-mounted arrays require slopes under 5-10%:
• Buildable area identification
• Grading requirements
• Panel row spacing
• Access road routing

Drainage tile design—steeper slopes allow wider drain spacing and smaller diameter pipe.

Logging road planning, harvest unit delineation, and erosion control on steep terrain.

Grade compliance verification and earthworks tracking throughout project lifecycle.
