Estimation of Small Area Populations Using Remote Sensing and Other Approaches

摘要

This paper documents the results of an assessment of a variety of techniques for estimating residential population for a five-mile radial grid around a nuclear power plant. The study area surrounded the proposed Limerick Nuclear Power Plant located near Philadelphia, PA. Techniques evaluated ranged from the use of air photos to infer population from housing distributions to the use of Landsat data to characterize probable residential population around the plant site. Although the techniques involving the use of Landsat data provided good results, a simple proportional area allocation method and the current procedure used by Oak Ridge National Laboratory for the Nuclear Regulatory Commission were among the best techniques. Further research using other sites and better resolution satellite data is recommended to investigate the possible refinement of population estimates using remote sensing media. 34 references, 10 figures, 2 tables.
