This document describes the concept and activities connected with Deliverable 3.5 “Report of new features of the Sentinel Hub App”. The main goal is to showcase how to filter and subset the results returned by the Umbrella using other data sources, such as GEOSS-related datasets. For this, the main structure of D3.5 consists of an introduction to the Umbrella Sentinel Access Point, the description of the extended features for filtering and subsetting the results returned by the Umbrella based on the condition of external data sources, as well as some examples and scenarios for the use of the extended application. The developed tool will facilitate Pilot studies in decreasing the volume of data needed to be acquired and processed, minimising the storage capacity and computational complexity of the Climate Change (CC) related applications. Lastly, at the end of the document, limitations and future steps to improve the tool are reported, which mainly focus in the availability of accessible external APIs to be linked/blended with Umbrella, and in the possible integration of more external datasets into the developed tool.
