The **Geohazards Exploitation Platform (GEP)** is a cloud-based Earth Observation platform tailored for **geohazard monitoring** , **terrain motion analysis** , and **critical infrastructure assessment**. Operated by **Terradue** and funded by the **European Space Agency** , GEP hosts a wide range of processing services that empower users to transform EO data into actionable insights for science, operations, and disaster response.

With a growing community of over **3,200 registered users** across research institutions, public agencies, and industry, GEP has become a **central hub for EO-based geohazard services** , offering both **on-demand processing** and **systematic monitoring capabilities**.

## A Platform Purpose-Built for Geohazards

GEP offers more than **25 specialised EO services** , including:

- **Visualisation services** for full-resolution and change detection imagery
- **Advanced SAR and optical data processing** , including:
  - Classic and advanced InSAR for Persistent Scatterers (PS) and Small Baseline (SBAS)
  - Horizontal ground motion detection from optical time series
  - Digital surface model (DSM) generation from stereo optical imagery

These services support a wide range of use cases such as **volcanic activity tracking** , **subsidence analysis** , **earthquake response** , and **landslide detection**. All services operate on cloud infrastructure, with access to over **400 TB of EO data** , including Sentinel-1, Sentinel-2, Sentinel-3, ERS, ENVISAT, Landsat-8, SPOT, and Pléiades.

## Designed for Users — from Research to Operations

GEP is designed for different user types:

- **Researchers and scientists** , who use GEP for pilot studies, validation campaigns, and long-term monitoring
- **Public authorities and civil protection agencies** , who rely on GEP for hazard mapping and disaster response
- **Service developers** , who can deploy their own algorithms using the **EO Application Package** model

Over **350 active contributors** use GEP not only to run services but to **publish new content and datasets**. This enables collaboration and continuous service innovation.

## Operational Models: Flexible Access and Sustainable Growth

GEP is offered under a **Data-as-a-Service (DaaS)** model with:

- [**Pay-per-use**](https://portal.geohazards-tep.eu/t/55) options for occasional users
- [**Monthly subscriptions**](https://portal.geohazards-tep.eu/t/getting-started/55) for operational or intensive use
- [**Sponsored onboarding**](https://nor-discover.org/en/sponsorship/) through ESA’s Network of Resources (NoR) program

The [NoR sponsorship strategy](https://nor-discover.org/en/sponsorship/) helps new users—particularly from academia and public institutions—test the platform without initial cost. Many then transition into commercial users, reinforcing GEP’s **sustainable service model**.

GEP is in use across multiple continents, including Europe, Southeast Asia, Africa, and the Americas. Highlights include:

| Title | Region | Description | Link |
| --- | --- | --- | --- |
| Central Chile Earthquake (September 2022) | Chile | GEP provided InSAR analysis to detect surface deformation and assess the earthquake’s impact on infrastructure. | [Link](https://discuss.terradue.com/t/measuring-coastal-subsidence-after-recent-earthquakes-in-chile-central-using-sar-interferometry-and-gnss-data/1099) |
| Santorini Volcano Unrest Phase (2023) | Greece | GEP services were used to monitor another phase of volcanic unrest at Santorini, one of the most iconic volcanoes in the Aegean Sea. | [Link](https://discuss.terradue.com/t/santorini-volcano-experiencing-another-unrest-phase/1256) |
| Turkiye–Syria Earthquakes (February 2023) | Turkey - Syria | GEP facilitated the generation of interferograms and surface rupture mapping for the M7.8 and M7.7 earthquakes, supporting disaster response. | [Link](https://discuss.terradue.com/t/turkiye-syria-earthquakes-displacement-maps-of-the-gdm-opt-etq-service-publicly-available/1165) |
| Morocco Earthquake (September 2023) | Morocco | Radar interferogram generated using Sentinel-1 acquisitions to analyze the impact of the M6.8 earthquake. | [Link](https://discuss.terradue.com/t/radar-interferogram-over-morocco-using-the-copernicus-sentinel-1-acquisitions-of-30-august-2023-11-september-2023/1215) |

GEP services are licensed to users in over 20 countries, supporting both local studies and international development projects.
