Echelon is based on satellite images captured roughly from 2000 to the present. It depicts various so-called SIGINT (signals intelligence) stations that serve the interception and the collection and analysis of electronic signals, as for exaple commercial and other sattelite communication. These facilities are part of the ECHELON network. Most of its technology allows commercial and other satellite communications to be intercepted. These stations are operated by five nations: the U.K., U.S., Canada, Australia and New Zealand - and their allies, which have signed the UKUSA Agreement. The network was created in the early 1960s to monitor the military and diplomatic communications of the Soviet Union and its Eastern Bloc allies during the Cold War. Nowadays, the stations have different intelligence targets.
When surveillance is ubiquitous and therefore an abstract notion - then concentrating on changes on a certain geographical position like the appearance of new buildings and technology - is a possibility to specify the issues. It is also important to think about the historical notion of signal intelligence, it is nothing new, it isn't something that suddenly happened, it has almost always been connected to state power. The differences that are the result of better data processing capabilities translate to changes in scale and method - the search for anomalies in digital and biophysical patterns - though this does not always translate to better efficiency.
