# Fdot Sinkhole Signals

`GET /api/v1/fdot/sinkhole-signals/{lat},{lon}`

## Request

- Base URL: `https://www.deepmapai.com`
- URL: `https://www.deepmapai.com/api/v1/fdot/sinkhole-signals/{lat},{lon}`
- Auth: none declared

Computed sinkhole indicator signals from FDOT bridge and road data.

Fuses bridge condition trends, incident clustering, and road
closure patterns to produce ML features for the Ghost Network
sinkhole predictor.  Returns both individual signal scores
(0-1) and a composite score.

Signals computed:
    - bridge_condition_decline: NBI rating trend slope
    - scour_critical_density: fraction of scour-critical bridges
    - incident_cluster_score: spatial clustering of karst incidents
    - pavement_collapse_reports: recent collapse / subsidence count
    - road_closure_anomaly: closure rate vs historical baseline
    - subsidence_indicator: combined infrastructure distress index

**Pricing:** Included in subscription tiers (legacy list price: GET /api/v1/billing/pricing).
