Paper Abstract

While Mr. Hasell's argument that optimal earth resource inventory and monitoring systems will necessarily require data from several sources is a sound one, a comment on the use of the phrase "multistage approach" is perhaps in order. The basic problem is to differentiate between two real and significantly different, though complementary, approaches to quantity estimation. The first method involves the use of several levels of information--satellite imagery, low and high resolution aircraft data in resource areal extent classification inventories calibrated to known ground data models. The second estimation technique ultilizes all data levels in an integrated, randomized sample design. The former approach is that described by Mr. Hasell while the latter embodies sample plans such as introduced in William G. Cochran's Sampling Techniques (Second Edition, John Wiley & Sons, Inc.).
