Aplication of Remote Sensing Technology to Population Estimation

This paper attempts to explore a new avenue of urban smallregional population estimation by remote sensing technology, comprehensively by using a residence count method, area (density) method and model method, and taking Tianjin City as an example. Firstly, the author proposes theoretical basis for population estimation by remote sensing. Secondly, two mathematical models of population are constructed on the basis of remote sensing data. Finally, some viewpoints on the principled problems about the practical application of remote sensing to population estimation are put forward.
