Based on the data of GF-2 remote sensing images and GIS, this paper mainly constructs the model of regional security situation. Through the data preprocessing with the remote sensing image processing software, on the basis of the extraction of the information of vegetation, road, and water and housing construction resources, this paper constructs the evaluation index system for the regional security situation by using spatial data analysis technology. Combined with the study of the real situation of regional police information, this paper uses the expert evaluation method to normalize each detailed index, and further uses the analytic hierarchy process to get the weight value of each index. In the grid GIS spatial environment supported by computer technology, the security situation map of the study area is obtained through security indexes. A breakthrough is made when the remote sensing space technology is applied to the public security business. According to the regional security situation map, combined with the field visits in the study area, this paper provides support for the public security affairs by using the research results.
