What is a Slope Map?

A slope map transforms complex topographic information into an easy-to-read color-coded visualization where each color represents a different degree of steepness. Generated from elevation data, it shows how steep the terrain is across any surveyed area.

Slope maps are created by analyzing Digital Terrain Models (DTM), precise 3D representations of the ground surface. The system calculates the rate of change in elevation between neighboring points and expresses this as either:

• Degrees (0° = flat, 90° = vertical cliff)
• Percentage (0% = flat, 100% = 45° angle)

The result is typically displayed using a gradient color scale: green for flat areas, yellow for moderate slopes, and red or purple for steep terrain.

LidarVisor creates slope maps from LiDAR point cloud data with precision. The platform first classifies ground points to build an accurate DTM, then automatically calculates slope values across the entire surveyed area.

The result is an interactive layer you can overlay on your 3D visualization, helping you quickly identify terrain challenges and make informed decisions, all without needing specialized GIS software.

• Instant terrain assessment: Visualize slope conditions across entire survey areas in seconds
• Risk identification: Quickly spot areas prone to erosion, landslides, or drainage issues
• Planning optimization: Make informed decisions about construction sites, road alignments, and infrastructure placement
• Multi-industry value: Applicable to construction, forestry, environmental management, and utility corridors
