title: ERTS: Surveying Earth's Resources from Space.
abstract: Several errors occurred in the Research News story "ERTS: Surveying earth's resources from space" (6 Apr. 1973) by Thomas H. Maugh II. In column 3, page 50, the statement, "It thus maps an area of about 6.5 km(2) every day," should read "6.5 x 10(6) km(2)." In Fig. 3, the land masses are identified as Manhattan and Staten Island; actually, the spit at the left of the figure is Sandy Hook, New Jersey, and the barrier beaches further north are Rockaway, Long Beach, and Jones Beach, from left to right. The negative for Fig. 4 was inadvertently flipped over so that the illustration is a mirror image of the actual picture. It has also since been brought to the author's attention that " the previously unsuspected difference in salinity" in the Great Salt Lake described in the caption of Fig. 2 was, in fact, well known before the ERTS picture was taken.
