Method and system for determining size of population distribution grid

The invention discloses a population distribution grid size determination method and system, and the method comprises the steps: obtaining noctilucent remote sensing data, carrying out the first preprocessing of the noctilucent remote sensing data, and generating a noctilucent remote sensing pattern spot; acquiring land surface coverage data, performing second preprocessing on the land surface coverage data, and generating pattern spots of all levels of house building areas; intersecting and superposing the noctilucent remote sensing pattern spots and the pattern spots of all levels of house building areas to generate a pattern spot overlapping and intersecting area; and calculating a population distribution grid scale based on the pattern spot intersection area. According to the method, the population grid scale in the research area is determined on the premise of not using population data. 本发明公开了一种人口分布格网大小确定方法及系统，该方法包括：获取夜光遥感数据，对所述夜光遥感数据进行第一预处理，生成夜光遥感图斑；获取地表覆盖数据，对所述地表覆盖数据进行第二预处理，生成各级房屋建筑区图斑；将所述夜光遥感图斑与所述各级房屋
