We collect information overtly (openly) and covertly
(secretly).
-
Reading foreign newspapers and magazine articles,
listening to foreign radio, and watching overseas television
broadcasts are examples of “overt” (or open) sources for us.
-
Other information sources can be “covert” (or
secret), such as information collected with listening devices and
hidden cameras.

We can even use space-age technology like satellite
photography.
-
For instance, some analysts could actually view how
many airplanes are present at a foreign military base by looking at
a picture taken from a satellite in space.
