Land use Dynamic Monitoring using Multi-Temporal SPOT Data in Beijing City from 1986 to 2004

Remote sensing dynamic monitoring of land use can detect the change information of land use and update the current land use map, which is important for rational utilization and scientific management to land resources. This paper discussed the technological procedure of land use dynamic monitoring, including the process of remote sensed images, the information classification and extraction of remote sensed imagery, and analysis of land use changes. Based on SPOT imagery data in three periods, the paper took Beijing city as an example, extracted the land use information during 1986-2004, and the land use changes were required in the period. The object-oriented method was used to extract information, and contrastive method after classification was used to confirm change zones.
