Modern technology has developed to such an extent that it has hardly left anything out of the reach of the humans. On the other hand, man is constantly on the lookout for newer ways of analysing the resources they have in hand and then expanding them for better usage and applications. For instance, defence and intelligence operations need continuous care and scrutiny as they further involve a lot of other issues. The concept of Geospatial intelligence is of special significance in this regard. The process of deriving this intelligence revolves around exploitation of geospatial information that assesses, explains and also visually brings forth the physical features as well as geographically indicated activities on the Earth. Imagery has an important role to play. Having said that, geospatial intelligence is intricately linked to the subject of Human Geography. Conferences that address topics on everything that concerns the defence and intelligence, attempt at a thorough study of this particular branch of geography along with other essential concepts such as that of the ISR resources, remote sensing, GIS data and mapping and so on.
The field of human geography is an ever-expanding one, calling for the fact that the advancements are practically applicable within the geospatial intelligence communities. However, before anything else, it is important to know about the principle in details in order to be able to focus on its usability. As one of the two major sub fields of the discipline of geography, human geography is, at best, a study of the world and its people, with greater emphasis on the cross- cultural relations among them. The principal difference between this specific branch with that of the popular physical geography is that the former entail a study of human activities. Owing to the fact that this study is often based on qualitative research methodologies, the discipline finds its application in the discussion and analysis of serious issues related to defence and intelligence.
Equally important is the concept of ISR, the full form of which stands as intelligence, surveillance and reconnaissance. The ISR resources, too, need to be studied and analyzed in the context of geospatial intelligence. Nevertheless, while the accumulation of the resources come later, it is necessary to understand what ISR is all about in the vey first place. It is principally an activity that coordinates and integrates the devising of and the operation of sensors and assets. It is the processing, exploitation and dissemination of systems, which is carried out with the purpose of supporting the existing operations as well as paving the way for the future ones. The ways of developing the ISR resources are found out by means of discussion on the matter.
Attending the annual meetings and gatherings would be an essential way of gaining deeper insight into these topics, whether it is human geography or anything else. People coming from different countries and backgrounds throw light on the importance of integrating ISR resources and various other issues that need immediate focus and attention. It is often through conferences that ground breaking theories and strategies are developed.
Defence Geospatial Intelligence or DGI is a Human Geography national security conference, where various issues with respect to defence and intelligence operations are ISR Resources analyzed and discussed. It is undoubtedly one of the largest annual gatherings.
