The Global Geothermal Energy Database (GGED) of the International Geothermal Association (IGA) is a web application based on a database containing global and country-specific geothermal information, and refers to both electricity generation and direct use of geothermal heat. The application, built using an open-source Business Intelligence platform, can be accessed through the IGA website. The application functionalities are: • the database "list of information" regarding geothermal fields and plants, direct uses, geothermal turbine manufactures and geothermal companies; • the "reports", with predefined aggregation of useful data in a standard format; • the "chart", producing pie charts and bar diagrams of data, which can be dynamically sorted and aggregated. • the "maps", using a webGIS tool for geothermal fields location, allows also to browse the maps, to zoom, to measure distance, to pan and to query for further analysis. Aggregation and filtering are options to summarise and organise data for direct use, power plants by region, category and operative status and GEA code. An on-line help document is downloadable from the menu of the application.
