Surveying the Unseen: How LiDAR Reveals Hidden Terrain

In the heart of Kentucky’s hills and Tennessee’s mountains, lies more than just the terrain we see—there’s a hidden landscape below dense forests, beneath the canopy, and across difficult terrain. That’s where LiDAR (Light Detection and Ranging) becomes an invaluable surveying tool. AJC uses LiDAR technology to collect high-resolution, 3D data that reveals the fine contours of the earth’s surface—even in areas where traditional surveying methods fall short.

What Is LiDAR, Exactly?

LiDAR works by emitting rapid laser pulses from aircraft, drones, or ground-based systems. These pulses bounce back when they hit the ground, trees, or buildings. By measuring the return time of each pulse, surveyors can construct extremely accurate elevation models—even through heavy vegetation or rough terrain.

Why It Matters for Surveying

• Topography in Detail: Unlike traditional methods, LiDAR can show every dip, ridge, and elevation change—crucial for grading plans and stormwater design.

• Efficient Coverage: LiDAR can cover vast, inaccessible areas quickly, improving efficiency and safety.

• Preserving Natural & Cultural Features: It helps identify archaeological features, floodplain changes, or sensitive habitats that might otherwise go unnoticed.

When Should You Consider LiDAR?

LiDAR surveys are ideal for:

• Large or heavily forested sites

• Floodplain modeling and FEMA maps

• Environmental impact studies

• Infrastructure planning in rugged terrain
