A so-called "Global Heat" view from the NSA program Boundless Informant, the existence of which was first made public by Britain's Guardian newspaper. According to internal NSA documents seen by SPIEGEL journalists, it is an elaborate new system that allows the NSA to visually track their current data collection possibilities practically in real time. The color-coding, which varies according to time and evaluation, ranges from green (least intensively monitored) to yellow to orange to red. In January 2013, the most monitored countries were -- not surprisingly -- Iran, Afghanistan and Pakistan. Germany came up yellow for the same time period and type of evaluation, signifying relatively high accessibility.
