LiDAR Uses & Applications
What is LiDAR?
LiDAR (Light Detection and Ranging) uses lasers for accurate 3D measurements:
Terrain Models: LiDAR-derived DSM/DEM Generation with Tailored Outputs
ASPRS LAS 1.4: Enhances point classification and memory efficiency
Accurate and Discreet: Precise surface/object lidar point clouds, even from oblique angles
3D (X, Y, Z): Coordinates and point attributes (intensity, returns, classification) dictate density and accuracy
2024 Preliminary LiDAR - Available Now
The 2024 preliminary LiDAR data is now available, providing high-resolution elevation information ideal for planning, flood analysis, and environmental monitoring.
LiDAR/Elevation Data Pricing
Current LiDAR/Elevation Data Pricing
| Product | Full Extent Price | 1 to 50 Tiles | 51 to 200 Tiles | 201 to 1,000 Tiles | 1,001 to 2,000 More Tiles | 2,001 or More Tiles |
|---|---|---|---|---|---|---|
| 2024 Preliminary LiDAR/Elevation Data 1 | Not Available | $100 per tile | $75 per tile | $50 per tile | $35 per tile | $25 per tile |
1 Please note that the 2024 Preliminary Dataset is not fully "cleaned" and QC'ed. It still contains artifacts (vegetation, structures, bridge decks, etc.) and the DEMs are not hydro-flattened.
