Research in the Method of Population Estimation in Urban District Based on EO data
基于对地观测数据的城镇人口估算方法研究（英文）

In this paper,a method to estimate the population in urban districts by using EO (Earth Observation) data has been studied and discussed.Firstly,in this investigation residential districts have been classified into three kinds,which are high-dense,middle-dense and low-dense,and the area of each kind has been calculated by interpreting IKONOS.Then,the correlation between the population and the residential area has been studied by using the linear analysis,and an equation showing the correlation between the population and the residential area has been determined.Finally,the equation between the population and the residential area has been tested.Results show that it is a reasonable and adoptable way to estimate the population by using EO data in some urgent situations in urban districts.
