 The paper examines the potential uses of two new satellite imaging systems, one providing high-resolution images of the Earth at night and the other capturing photographs from the International Space Station. The first system, known as the Visible Infrared Imaging Radiometer Suite Day-Night Band, VIRES DNB, provides detailed information about the intensity of light emitted by different areas on Earth. This can be used to identify large sources of light, such as airports, and to measure the amount of light emitted by individual cities. The second system, which captures photographs from the International Space Station, offers a much higher level of detail but does not provide any spectral information. However, it does offer street-level resolution, making it useful for epidemiological studies. Both systems show great promise for future research into human geography.
