The EOCHA Data Portal facilitates the access to heterogeneous datasets providing in a one-stop-shop the access services and basic data mining tools necessary to explore geospatial data i.e. in the context of the disease early warning systems. The Portal is based on the Multisensor Evolution Analysis (MEA) technology - an Earth Observation and geospatial data analysis tool empowered with OGC (Open Geospatial Consortium) standards and open source technologies to enable Big Data access and processing services. Key World Bank sectors can benefit from such climaterelated health risk assessment including Agriculture and Rural Development, Environment, and Health, Nutrition and Population in the regions that are afflicted by both high burdens of infectious disease and climate change - notably, Africa, South America, East Asia and the Pacific. This platform is produced under the 2016 World Bank (WBG) - European Space Agency (ESA) partnership, and is published in the partnership report: Earth Observation for Sustainable Development, June 2016
