Geospatial intelligence systems have been around for centuries, at least since the 21st of November 1783, when two men rose to a height of 900m and covered a distance of 10km in the first untethered flight of a Montgolfier hot air balloon. Despite the rapid acceptance of such concepts, it was still confined to a relatively select group who had real reasons to "need know" their locations accurately. Over the past ten years, however, there has been a real shift in our overall perception of GIS, and not just amongst the cognoscenti.
