Big Data is no stranger to the geospatial world; only it is known by several names. Perhaps Big Data is a way of defining a paradigm shift to a data-intensive collaboration where processes reinforce traditional database approaches.*
The explanation is extracted from the recently released Whitepaper addressing Big Data technologies on Earth Observation sector. Key findings to take on:
- more efficient and faster Big Data exploitation, timely delivery of meaningful extracted information are major challenges to overcome in the years ahead;
- added value services will integrate EO technologies with other different types of data: from in-situ data, which complement and validate the data gathered from space-borne and air-borne remote sensing, to Internet of Things (IoT) generated data, inputs from social media networks and citizen science approach;
- the Big EO Data collection, dissemination, processing and added value service delivery for end-users is, in fact, a technological challenge.
All the threats, the opportunities and the solutions are presented at large in the Whitepaper released by the Earth Observation & Geospatial Subgroup working in the Big Data Value Association (BDVA) within the Task Force 7- Applications.
The position paper is the Subgroup members’ contribution work, coordinated by TERRASIGNA.
