Data aggregation, V2

This deliverable provides information about the implementation of an API to serve aggregated data from resources relevant to past large-scale disasters and the aggregation of data coming from internal sources and devices, such as smart glasses, smart helmets, drones, and sensors.
As far as the past disasters are concerned, 7 relevant sources have been chosen that can be proven to be useful for crisis preparedness and search and rescue operations, after being evaluated according to specific criteria. Data aggregated and transformed from these sources are then served through an API to be used as part of a collective access point for the execution of experimental knowledge discovery algorithms.
The second section of D4.8 aims to present the data aggregation mechanism. This section settles down the available components that enable the aggregation mechanisms that process the real-time data and combine them with rest data, such as historical data, data from COncORDE.
