Manual of Remote Sensing
- In the broadest sense, the measurement or acquisition of
information of some property of an object or phenomenon, by a
recording device that is not in physical or intimate contact with the
object or phenomenon under study; e.g., the utilization at a
distance (as from aircraft, spacecraft, or ship) of any device and its
attendant display for gathering information pertinent to the
environment, such as measurements of force fields, electromagnetic
radiation, or acoustic energy. The technique employs such devices as
the camera, lasers, and radio frequency receivers, radar systems,
sonar, seismographs, gravimeters, magnetometers, and scintillation
- The practice of data collection in the wavelengths from ultraviolet
to radio regions. This restricted sense is the practical outgrowth
from airborne photography. Sense (1) is preferred and thus includes
regions of the EM spectrum as well as techniques traditionally
considered as belonging to conventional geophysics.

ones, collected by the Canada Centre for Remote Sensing.
