AN AERIAL FRAME TECHNIQUE FOR POPULATION ESTIMATION: PROBLEMS, ACCURACY AND POTENTIALS

Resumo

A net residential land use concept of population estimation from aerial photographs was applied in estimating the population of two major and two mediumsized urban centres in Nigeria. A variety of aerial photographs (scale 1:6000 and 1:10,000) were utilized. A regression analysis of land use and population variables was made and the exponential coefficients of a population estimation model were established. The results provided some insights about the spatial patterns of population distribution in the neighbourhoods of rapidly urbanising cities in Nigeria. The application problems, accuracies and potentials of the aerial frame technique of population estimation are discussed.
