📡 LiDAR Modalities & Use Cases
Extreme-Spartan Cognitive Industries Pvt. Ltd.
🔍 Overview
LiDAR (Light Detection and Ranging) is central to ESCAPE-chip deployments for coastal disaster monitoring. Your architecture supports multi-modal LiDAR, enabling both terrestrial and aquatic mapping. This section outlines the three key modalities integrated into your payloads:
🧠 LiDAR Modalities
1. Topographic LiDAR
| Attribute | Value |
| Wavelength | ~1064 nm (Near-Infrared) |
| Target Surface | Land surfaces |
| Use Cases | DEM generation, terrain mapping, erosion modeling, infrastructure planning |
| Platforms | Drone, UAV, static beach sensors |
2. Bathymetric LiDAR
| Attribute | Value |
| Wavelength | ~532 nm (Green Laser) |
| Target Surface | Submerged surfaces |
| Use Cases | Underwater depth estimation, rip current modeling, shoreline bathymetry |
| Platforms | Drone-mounted, UAV with water-penetrating optics |
3. Short-Range LiDAR
| Attribute | Value |
| Wavelength | ~850–940 nm (Near-IR) |
| Target Surface | Near-field detection |
| Use Cases | Shoreline dynamics, wave motion, micro-topography |
| Platforms | Static perimeter sensors, rover payloads |

🔄 Integration with ESCAPE Architecture
- All LiDAR modalities are routed through the ESCAPE microcontroller
- Data is fused with GPS, IMU, and optical sensors
- Outputs feed into Edge AI inference for disaster detection
- Bathymetric LiDAR is critical for rip current depth modeling and drone dispatch targeting
📎 Deployment Strategy
| Deployment Tier | LiDAR Modalities Used | Purpose |
| Audit Drone | All 3 (Topographic + Bathymetric + Short-Range) | Full shoreline + underwater scan |
| Beach Perimeter Node | Short-Range + Topographic | Continuous monitoring |
| Emergency Drone | Bathymetric + Optical | Depth scan + live feed |
