Satellite Imagery

Satellite images are photographs of the earth or other planets made from artificial satellites. Satellites orbiting Earth have orbit elevations and time intervals to cover the globe and image the same area.

Satellites may have active or passive sensors. Passive sensors use reflected sunlight (solar radiation) to record objects on the ground and send digital image data in several spectral bands to the receiving stations on earth. These systems have multi-spectral scanners to collect data. Active satellites record reflected radiations which the sensors will send to the earth surface.

The BC Digital Imagery Service (DIS) warehouse has several series of imagery in its inventory, including Canadian RADARSAT 1 and 2.
