In previous videos, we’ve talked about the size of a pixel—called spatial resolution—and the content of a pixel—called spectral resolution. Now we’ll discuss temporal resolution, which is how often a pixel is collected. Temporal resolution depends on three factors: Past collection, in the form of an image library assembled over the life of a satellite or constellation of satellites; Current image collection strategies, based on today’s needs and technical abilities; and Future Collection Capabilities, which inevitably change as the world changes and our needs evolve.
