Discussion on the Technical Points and Changes of Urban Land Spatial Monitoring in 2023
Based on the high-resolution remote sensing images in 2023 and the latest relevant thematic information and combined with field surveys,the urban land spatial monitoring in 2023 is conducted by using the results of land change survey in 2022 as the base map. The monitoring work can grasp the total amount of urban construction,land use structure,infrastructure and service functions,which effectively support the work of national land spatial governance. This paper compiles and summarizes the urban land spatial mo-nitoring work in Jilin province in 2023,focusing on the technical points of the monitoring work and the changes compared with the mo-nitoring work in 2022. It provides reference for the urban land spatial monitoring work in the coming year.
