Defense Geospatial Intelligence (DGI) is one of the largest GIS Conference in Europe Since it's launch in 2003, the Defence Geospatial Intelligence (DGI) Conference & Exhibtion, has become the largest and most international annual gathering dedicated to the high-level discussion of geospatial intelligence and national security in both defence and intelligence operations. 

Addressing the use of geospatial information in scenarios such as international conflicts, defence operations, C4ISR, humanitarian disasters, crime, national security, border control, arms treaty monitoring and global climate change; the fundamental objective of DGI is to help organisations understand how to build the necessary infrastructure and architecture to take advantage of geospatial intelligence capabilities. 

DGI brings together heads of geospatial intelligence, remote sensing, GIS mapping, gis data and satellite imagery within the military, governmental and national security sectors as well as industry solution providers. It attracts professionals who are responsible for using and integrating geo based capabilities in their operations and organisations. DGI provides a unique forum for defence intelligence professionals to discuss and debate the development of geospatial intelligence capabilities.

Over 700 senior defence and security executives from 46 countries attend the Defence Geospatial Intelligence (DGI) in Westminster, London, to discuss the future role of GeoInt in their organisations, to debate new strategies, future collaboration plans, and to find solutions to their current Geo challenges.
