Five endpoints

Everything you need from a satellite

One API, five analysis types. Drop coordinates in, get answers out.

Change Detection

Identify what changed between two dates: construction, deforestation, flooding, land use shifts.

POST /api/v1/satellite/detect-changes

Feature Extraction

Pull NDVI, surface temperature, moisture index, and terrain metrics from any location.

POST /api/v1/satellite/extract-features

Temporal Analysis

Track how a location evolves over weeks, months, or years with trend forecasting.

POST /api/v1/satellite/analyze-temporal-trends

Anomaly Detection

Flag statistically unusual patterns compared to historical baselines for the same location.

POST /api/v1/satellite/detect-anomalies

Risk Scoring

Composite flood, wildfire, drought, and deforestation risk scores for any asset location.

POST /api/v1/satellite/score-risk

More coming

Object detection, building footprints, and SAR-based flood mapping are on the roadmap.

How it works

From coordinates to insights in seconds

Send coordinates and a date range

Pass a GeoJSON polygon (or bounding box) and a time window. No GIS setup, no raster files.

We process real satellite imagery

Satalyse queries Sentinel-2, Landsat 8, MODIS and other sources via Google Earth Engine, on demand.

Get structured JSON back

Every response is clean, typed JSON: scores, metrics, polygons, confidence values. Plug it straight into your app.

Use cases

Built for industries that depend on location data

Satalyse is industry-agnostic by design. The same API handles agriculture, insurance, climate, and beyond.

AgTech

Monitor crop health across thousands of farm parcels. Track NDVI trends, detect irrigation failures, and forecast yields, without physical sensors.

InsurTech

Verify property damage claims in minutes. Cross-reference change detection against claim dates and locations for fraud prevention and faster payouts.

Climate / ESG

Quantify deforestation, carbon sink changes, and environmental risk for ESG reporting and regulatory compliance.

PropTech

Score every property for flood, wildfire, and drought risk before underwriting. Embed into listing pages or due-diligence workflows.

Research

Access consistent, analysis-ready satellite metrics over time for academic studies, climate modelling, or humanitarian mapping.
