Examples (proof of concept) | openEO

This page gives a detailed description of the openEO proof of concept use cases. After the proof of concept, this stays in the API to have some basic examples. The proof of concept covered three clearly defined example use cases and how they are translated to sequences of API calls:

1. Deriving minimum NDVI measurements over pixel time series of Sentinel 2 imagery
2. Create a monthly aggregated Sentinel 1 product from a custom Python script
3. Compute time series of zonal (regional) statistics of Sentinel 2 imagery over user-specified polygons

Note: CORS and authentication is not included in these examples for simplicity. Repeating calls are also not included as it would not make much sense to list the same discovery requests (see Use Case 1, requests 1 to 6) for each use case individually.

Deriving minimum NDVI measurements over pixel time series of Sentinel 2 imagery.

A similar example (computing an EVI) is also available. (opens new window)

1. Requesting the API versions available at the back-end

   Request

2. Requesting the capabilities of the back-end

   Note: The actual request path depends on the response of the previous request.

   Request

3. Check which collections are available at the back-end

   Request

4. Request details about a specific collection (e.g. Sentinel 2)

   Note: The actual collection ID in the path depends on the response of the previous request.
