Space & Security

Curated by NextGEOSS

This pilot is being implemented by the European Union Satellite Centre:

The main objective of the Space and Security Pilot is to demonstrate, through a sample application, how Open Geo-spatial Data and Cloud Computing can support activities in the Security domain.

The pilot focuses on the detection and analysis of changes occurring on the surface of the Earth, in selected areas of interest and within predefined temporal intervals. The main categories of changes that are considered for analysis are related to human activity or involve man-made structures, urban or built-up areas.

The temporal scale of the analysis is in the order of months, while the spatial extent of the analysis is large areas (in the sense of Security applications, i.e. thousands of square km).

The structure of the pilot is centered around two main components:

1) SAR Change Detection

The SAR-based Change Detection component refers to a binary change detection workflow in which the temporal variation of Sentinel-1 satellites images is employed to detect changes affecting man-made objects or changes in landscape due to human activity (e.g. construction works). This component is based on results achieved in the EVER-EST project and the products generated by the processing chain consist of binary change detection maps. For showcasing the results one can refer to the EVER-EST Virtual Research Environment (VRE) here:

2) Multispectral Change Detection

The optical Change Detection component refers to a workflow in which the temporal variation of landcover classes observed in selected spectral bands of Sentinel-2 imagery (or variation of spectral indices) is employed to detect landcover changes occurring over selected areas of interest.
