Abstract

Early in 1972 the first Earth Resource Technology Satellite (ERTS-A) is scheduled for launch in near-polar orbit. It will carry three return-beam-vidicon (RBV) TB cameras and a multispectral scanner (MSS). In 1973 a post-Apollo manned space flight called SKYLAB will orbit the earth at an inclination of 50° to the Equator. In addition to other sensors it will carry a battery of six multispectral cameras identified as experiment S190. This paper compares the images expected from ERTS and SKYLAB with those already obtained from GEMINI/APOLLO, all in terms of the photographic criterion of resolution. Recently provided data have led to several changes in the resolution of ERTS-A forecast a year ago (Colvocoresses, 1970).

ERTS-A satellite imagery

The first satellite designed to survey the Earth's resources is scheduled to be launched in 1972. This satellite, known as ERTS-A, will telemeter frames of imagery each covering 100-nautical-mile squares of the Earth. Except for the internal anomalies in the sensor system, the imagery, after being properly scaled, rectified, and controlled, may be considered an orthographic view of the Earth and used as a planimetric photomap. The accuracy of this photomap will be limited, principally by the geometric fidelity of the sensor system rather than by external effects, such as relief displacement, which restrict the direct cartographic use of the conventional aerial photograph. ERST-A is not designed as a topographic mapping satellite but does have real potential' for thematic mapping particularly in areas now covered by topographic maps.

Photographic systems for Apollo

The primary objective of the Apollo Lunar Program is to provide data for landing sites. The primary objective of Skylab is to demonstrate the ability of men to operate in space for extended periods of time. As a consequence, neither the missions nor the cameras in either program are optimum for photogrammetric operations. Nevertheless they provide an opportunity to evaluate the contribution that photogrammetry and space can make to the exploration of our own and other planetary bodies in the solar system. New equipment includes: an 18-inch fl camera exposing 430 frames on a roll of 5-inch wide film; a panoramic system of 24-inch fl, 108° sweep, 4.5 by 45-inch film for 1650 exposures; a terrain camera of 3-inch fl, 4.5 X 4.5 film frame; a stellar camera of 3-inch fl on 35-mm film; and a laser altimeter. Six multispectral cameras, 6-inch fl on 70-mm film are planned for Earth photos from Skylab.
