report description:
the report introduced the progress of the research on the application of remote sensing data of nighttime lights to urban issues, including quality improvement of remote sensing data of nighttime lights and key technologies of cross-sensor correction. it studied the spatial structure of the urbanization process (physical attributes), such as the extraction of urban built-up areas, the analysis of the intra-city spatial structure and the spatial structure of urban agglomerations, and the socio-economic structure of the urbanization process (social attributes), such as the estimation of various socio-economic indicators (gdp, electricity consumption, total freight, carbon emissions, material social stock, etc.), the estimation of urban housing vacancy rates, and the estimation of the composite poverty index.
