Question 1

What is Satalyse?

Accepted Answer

Satalyse is a REST API that converts satellite imagery from sources like Sentinel-2 and Landsat into structured JSON data. It provides change detection, vegetation health metrics (NDVI, EVI, NDWI), environmental risk scores, anomaly detection, and temporal trend analysis for any location on Earth.

Question 2

What satellite data sources does Satalyse use?

Accepted Answer

Satalyse processes data from Sentinel-2 (10m resolution), Landsat 8 (30m resolution), MODIS (temperature at 1km resolution), SRTM (elevation at 30m), CHIRPS (precipitation), and JRC Global Surface Water. All data is accessed via Google Earth Engine.

Question 3

How much does each API call cost?

Accepted Answer

Pricing per call: Change Detection $0.50, Feature Extraction $0.20, Temporal Analysis $0.75, Anomaly Detection $1.00, Risk Scoring $1.50. Your first 50 API calls are free. Playground/demo calls are always free and don't count toward your limit.

Question 4

What is the resolution of Satalyse's satellite data?

Accepted Answer

The default data source, Sentinel-2, provides 10-meter per pixel resolution with a ~5-day revisit time. Landsat 8 provides 30-meter resolution. The minimum analyzable area is approximately 10m × 10m.

Question 5

Does Satalyse provide satellite images?

Accepted Answer

No. Satalyse processes satellite imagery and returns structured JSON with computed metrics, scores, and analytics. It does not return visual imagery, raster tiles, or raw satellite photos.

Question 6

How long does a Satalyse API call take?

Accepted Answer

First-time requests for a location typically take 60–180 seconds (1–3 minutes) as satellite data is processed via Google Earth Engine. Subsequent identical requests are served from cache instantly.

Question 7

What can I build with Satalyse?

Accepted Answer

Common applications include crop health monitoring platforms, insurance claim verification systems, environmental compliance dashboards, real estate risk assessment tools, deforestation tracking systems, and climate change analysis tools.

Question 8

Is Satalyse an alternative to Google Earth Engine?

Accepted Answer

Satalyse uses Google Earth Engine for processing but abstracts away all complexity. Instead of learning the GEE Python API, managing service accounts, and writing processing scripts, developers make a single REST API call and get structured JSON back. It's GEE made accessible via API.
