Living Maps of the Field Plotter: Analog Simulation of Selected Geographic Phenomena, Technical Paper No. 4.
Nunley, Robert E.
This technical report describes the operation of a field plotter and the kinds of geographic problems that the instrument can simulate. The field plotter is an easily operated analog computer which employs the electrically conductive sheet analog to simulate a wide range of physical and human-related spatial phenomena. The diffusion patterns of current in the sheet are mapped directly by marking and measuring voltage with a pencil probe. The rsulting map of electrical potential is a direct analog to the spatial distribution of response to a simulated geographic phenomenon. After a brief introduction, chapter two discusses the geographic concepts of location, distribution, and spatial processes and rates the manner in which the field plotter describes these concepts. Chapter three examines the technical theory behind the field plotter. The fourth chapter presents the operations of the field plotter. Chapter five examines six specific applications of the instrument to geographic problems and models. The sixth chapter describes how field plotter techniques can be applied to wider geographic problems. (Author/DE)
