1. Tools for Linked Geospatial Data Exploiting Open Data
Manolis Koubarakis
Brussels October 11-13, 2016

2. Motivation - Open EO Data
Lots of open Earth Observation data have been made available in the last few years too.

3. Motivation - Data Silos
All this data still exists in different data silos
(e.g., different EO archives).

4. Main Objectives
1. Open up existing EO silos by moving them over to the linked data paradigm.

5. Main Objectives
2. Stay close to the real world: Develop services that heavily utilize linked data:
Improving Greenhouse Gas Emission Inventories
Management of Urban Growth Challenges
Providing Economic and Ecological Advice to Farmers
Assess the Quality of European Seas
Monitoring Desertification
Hazard Information Services
Marine Services based on AIS Data
Groundwater modeling
