Abstract:Aiming at the demand for monitoring and change research on environment and resources in Kashgar of Xinjiang province, a rapid order-style dynamic monitoring and evaluation system on environment and resources was constructed. Based on ArcEngine components and rich functional classes, the system was built upon the combinations of orderly spatial analysis operations, "virtual raster" in.afr format as a decent medium for band operations on remote sensing images, and multithreading technology. The architecture of the system and its core functions were exhaustively introduced, including task management, information extraction on water bodies, vegetation and ice, dynamic monitoring and evaluation, and thematic map production. Furthermore, the system application examples were presented. Meeting the requirements on operational applications, the system provided a good way to timely monitor changes and developments on environment and resources in a region, thus contributing to the regional economic development. The system can be widely used in the field of monitoring on environmental factors and resources, which displayed certain versatility and scalability.
