Abstract A thesis is proposed to show that the availability of repetitive observations from satellites yields information of significant benefit to the study of geography. A specific example of land-use survey of a selected test site is used to test the thesis. Data from the satellite LANDSAT-1, from aircraft at very high and medium altitudes, and from ground survey are used in the test experiment. Validation of the thesis statement requires definition of the terms, "benefit" and "significant." This is accomplished by reference to published information needs of selected geographers. A set of five needs is extracted: (1) develop new approaches and ways of measuring interrelationships, (2) attempt to study all significant phenomena in an area, (3) include temporal data, (4) study human/nature relationships, and (5) determine areal distributions and pattern associations. The thesis is placed in historical perspective by discussion of the importance of reflective observation in past geographical discoveries. It is shown that the rapid traverse studies which began forty years ago are analogous to observations from spacecraft. Design of the test experiment in land-use survey establishes the rationale of the experiment, selects the test site in Madison County, Alabama, establishes objectives and limitations, and out-line tests to determine if objectives are met. Technical details of factors affecting conduct of the experiment are given. These include resolution limits, data gathering, observation modes, and the land-use classification system. Conduct of the experiment is described, and in the analysis of data a number of maps are produced. Using the maps as information products, the test are applied to show that experimental objectives were met. The results are stated in terms of questions raised by the thesis; the five information needs are each examined relative to the experiment findings, for example. The success of the study in confirmation of the thesis is shown. Important findings, unanswered questions, conclusions, and recommendations complete the report.
