📡 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
