TEMPORAL AND DYNAMIC OBSERVATIONS FROM SATELLITES
George A. Rabchevsky · Photogrammetric Engineering & Remote Sensing · 1977
The sampling of terrestrial features or environmental phenomena by an airborne or satellite sensor is especially significant when repetitive surveys are required. Dynamic and short-lived natural events need to be detected rapidly and repeatedly for meaningful results. A series of satellites now provide a hitherto unavailable capability for detecting and mapping dynamic terrestrial features and environmental events on a global, repetitive, and temporal basis. The paper summarizes briefly some of the stellite missions and in a tabular form classifies the time-scale requirements for observing some of the dynamic events. /Author/
