What kinds of real-world use cases are featured on copernicus.eu?

Updated

Copernicus use cases show how satellite Earth observation data is turned into practical decisions, and the examples on copernicus.eu fall into a few recurring categories: environmental incident response, maritime surveillance and enforcement, and thematic applications tied to the Copernicus Thematic Hubs (health, coastal, energy, Arctic and heritage). Two featured examples illustrate the pattern: drift modelling to trace a vegetable oil spill along Finland's Hanko Peninsula, and a maritime decision-support system for law enforcement, search operations and pollution control. Note that copernicus.eu is now an archive, so current use-case content and the Image of the Day are published on the new EU Space website.

The two featured use cases, explained

Drift modelling for a vegetable oil stranding (Gulf of Finland)

On 27 January 2025, clumps of solidified vegetable oil were found along a 25 km stretch of coastline on Finland's Hanko Peninsula. The substance was not toxic but posed risks to wildlife. Suspecting it came from a passing vessel's cargo tank wash, Finnish authorities launched an investigation, using drift modelling to work back from where the oil came ashore toward its likely source.

What makes this a useful template for reading other use cases: it combines an observed event (oil on the coast), a modelled reconstruction (drift), and an enforcement outcome (identifying a suspect vessel). When you browse similar cases, look for that same chain — observation, model, decision.

Maritime surveillance for law enforcement, search and pollution control

The COSNORTH-SEMAR decision-support system is described as enhancing maritime surveillance and law enforcement along a northern sea area. Its stated functions — supporting law enforcement, search operations and pollution control — show how Copernicus marine data feeds operational tools rather than standing alone as raw imagery.

What categories of use cases to expect

Category What the case typically shows Example on the site
Pollution and incident response Tracing a spill or stranding back to a source Vegetable oil drift modelling, Hanko Peninsula
Maritime surveillance Decision support for patrols, search and enforcement COSNORTH-SEMAR
Thematic hub applications Data applied to health, coasts, energy, the Arctic or heritage Linked from each Thematic Hub

The Thematic Hubs act as entry points to use cases in their domain. The Health Hub covers environmental data relevant to physical and mental health and well-being; the Coastal Hub offers open and free access to selected coastal Earth observation data from the Sentinel satellites and all Copernicus Services; the Energy Hub connects environmental data to the green energy transition; the Arctic Hub provides data, interactive maps and thematic use cases for the region; and the Heritage Hub supports monitoring and management of cultural and natural sites.

How to view more use cases

  1. Open copernicus.eu and scroll to the "Use cases" section, where featured cases appear with a "View more" link.
  2. To browse by topic, go to the relevant Thematic Hub (Health, Coastal, Energy, Arctic, Heritage) and look for its use-case or interactive-map section.
  3. For current editorial content — including the EU Space Observer articles that often profile applications — use the new EU Space website, since the Image of the Day and EU Space Observer have moved there.

Expect the archive site to remain useful for older case write-ups, while new material appears on the EU Space site.
