Abstract

The present invention provides a population density analyzing system based on high resolution satellite remote sensing data, comprising: a remote sensing data acquisition module, a land feature type determination module, a population coefficient determination module, a grid division module and a population density determination module. Compared with the prior art, the present application calculates the population density in each grid respectively using the grid as the unit so that more specific population density distribution in a target area can be calculated. Compared with the existing technology, the system is more accurate. On the other hand, based on the remote sensing data, the present application can accurately determine the forming of the land feature types in the target area, so as to accurately determine the population coefficients corresponding to different land feature types to ensure high accuracy of the finally calculated population density.

Description

technical field

[0001] The invention relates to the technical field of population density analysis, in particular to a population density analysis system based on high-resolution satellite remote sensing data combined with surface object types. Background technique

[0002] Population density is the number of people living on a unit area of ​​land. It is an indicator of the density of the regional population. It can be used to measure the level of economic development and urban construction of a region. It can also be used for national and local macro-control, urban Development planning provides data support. In addition, accurate population density distribution data can help enterprises, institutions and entrepreneurs make reasonable decisions about location selection and industrial layout.

[0003] At present, the population density is generally calculated based on administrative divisions. For example, dividing the total population of a county by the area is the populatio...
