Pipeline

From orbit to API in hours

Every 5 days, our pipeline ingests the freshest Sentinel-2 pass over Lagos, computes flood indices, and serves scores via REST — no manual intervention.

01
🛰
Sentinel-2 Acquisition
ESA's Sentinel-2 satellite passes over Lagos every 5 days. We ingest L2A (atmospherically corrected) tiles from Copernicus Data Space — free, open, no per-image cost.
02
📡
Band Processing
We download only the two bands needed — Green (B03) and NIR (B08) — at 10m resolution and clip to the Lagos metro bounding box.
03
🌊
NDWI Computation
Modified Normalized Difference Water Index (MNDWI) separates water from built surfaces in urban Lagos — more accurate than standard NDWI for dense city environments.
04
📍
Neighborhood Scoring
Each SabiGround location is sampled with a 3×3 pixel window (30m × 30m) and normalized to a 0–1 flood risk score with LOW / MODERATE / HIGH / CRITICAL labels.
05
⚡
REST API Delivery
Scores are served via JSON API at api.sabiground.app — queryable by neighborhood name, lat/lng radius, or risk threshold. Webhook alerts on escalation events.
06
🌍
Ground Truth Layer
Satellite data is enriched with crowdsourced ground reports from SabiGround's Lagos user network — the only combined satellite + human validation layer for Lagos flood risk.
API Reference

Simple. Queryable. Real.

Two endpoints cover 90% of use cases. No proprietary SDK, no data format conversion — just JSON over HTTPS.

Use Cases

Who buys Lagos flood data

The $9.5B in Lagos flood losses from 2024–25 created an active market for ground-truth risk intelligence. These are the buyers.

🏦
Parametric Insurance Triggers
Use NDWI scores as satellite-derived flood triggers for parametric insurance policies — the same data type used in the Lagos State $7.5M parametric flood insurance deal, at open-source cost.
Swiss Re AXA Climate Descartes Underwriting Africa Re
🚢
Logistics Route Intelligence
Apapa Port handles 70% of Nigeria's imports. Real-time flood risk scores for port access routes help logistics operators reroute before events, not after. API integrates directly into TMS systems.
DHL Maersk FedEx Bolloré Logistics
🏗
Property & Infrastructure Due Diligence
Score any Lagos address for flood risk before acquisition, lending, or development. Historical NDWI trends reveal which areas have worsened over time — a signal invisible in static flood maps.

📊
ESG Physical Climate Risk Disclosure
SEC and ISSB climate disclosure requirements now mandate physical risk data for African portfolio companies. SabiGround provides the Lagos neighborhood-level data layer that global ESG platforms lack.

Data Provenance

Open satellite data.
Proprietary intelligence.

The underlying satellite imagery is free and open from ESA. The value we add is the pipeline, the neighborhood scoring methodology, the ground truth layer, and the API — built specifically for Lagos.

ESA Copernicus Programme
Sentinel-2 L2A (10m)
CDSE Open Access
NDWI / MNDWI
Built by Volition Tech
Hosted on OCI
Context: The Lagos State Government's $7.5M parametric flood insurance deal (March 2026) used ICEYE SAR satellite data as its flood trigger. SabiGround delivers comparable optical flood extent data from ESA's free Sentinel-2 constellation — validated against ground reports from our Lagos user network.
