Earth Observation data are currently showing an unprecedented scenario in terms of variety, volume, velocity, veracity and value; moreover, datasets to be used for security applications can be composed also by geospatial data coming from other sources. Thus, the key challenge in the Space and Security domain is to improve the capacity to access, process and analyse this huge amount of heterogeneous data to provide decision-makers with timely, clear and useful information.
An important value provided by EO datasets is the possibility to identify certain features or changes on the Earth’s surface at various spatial and temporal scales. Change Detection is a transversal technique supporting the monitoring of urban, built-up and natural environments by identifying relevant changes within areas of interest. The provided information constitutes a valid support to address environmental, scientific, humanitarian, security or political issues.
Within this context, the objectives of the Space and Security pilot in NextGEOSS are:
