## Overview

The Landslide Intelligence Engine exposes a FastAPI backend for location-based susceptibility, environmental triggers, combined hazard scoring, and data-source status; the README also describes a React/MapLibre GIS dashboard. The main scoring path is hazard assessment calling susceptibility and trigger calculations. Trigger data comes from Open-Meteo when available, with demo fallback; ground movement and detection inputs are mocked. The tree does not show frontend source, so the dashboard is represented by its listed `surakshasetu` entry; its implementation and detailed API wiring are not inspectable here.

Main entry points: [`backend/app/main.py`](https://github.com/soumyakoley1975/sih26/blob/landslide/backend/app/main.py) (FastAPI app), [`backend/app/api/routes/hazard.py`](https://github.com/soumyakoley1975/sih26/blob/landslide/backend/app/api/routes/hazard.py) (Hazard scoring), [`backend/app/api/routes/trigger.py`](https://github.com/soumyakoley1975/sih26/blob/landslide/backend/app/api/routes/trigger.py) (Trigger scoring), [`surakshasetu`](https://github.com/soumyakoley1975/sih26/tree/landslide/surakshasetu) (GIS dashboard)
