Click here for a larger map - it wont fit on this screen. Here's the caption in the Guardian:
The color scheme ranges from green (least subjected to surveillance) through yellow and orange to red (most surveillance). Note the '2007' date in the image relates to the document from which the interactive map derives its top secret classification, not to the map itself.

The focus of the internal NSA tool is on counting and categorizing the records of communications, known as metadata, rather than the content of an email or instant message.Nice to know that Wikipedia already has pages on both PRISM and Boundless Informant.
The Boundless Informant documents show the agency collecting almost 3 billion pieces of intelligence from US computer networks over a 30-day period ending in March 2013. One document says it is designed to give NSA officials answers to questions like, "What type of coverage do we have on country X" in "near real-time by asking the SIGINT [signals intelligence] infrastructure."
An NSA factsheet about the program, acquired by the Guardian, says: "The tool allows users to select a country on a map and view the metadata volume and select details about the collections against that country."
