Research on Urban Built-Up Area Extraction Based on Multi-Source Remote Sensing Satellite Data Fusion
Taking a certain city as the research area,based on the characteristics of urban built-up area,a method of urban built-up area extraction based on NPP/VIIRS high-light luminous data inversion and urban impermeable area inversion is constructed.The results show:The proposed algorithm for extracting urban built-up areas has high accuracy and can effectively reveal the internal relationship between urban built-up area and regional imper-meability rates,as well as luminous data activity.It is a feasible extraction method for urban built-up,and can also lay a good data foundation for further research such as urban sprawl analysis.
