英文摘要	Complex spatial processes are always involved in large GIS applications. A well-defined spatial process helps to the modeling and implementation of spatial applications to achieve more effective plans and managements. By analyzing the main characteristics, the formalized definition and the meta-model of spatial process are presented. A spatial process is mapped to a directed graph with spatial activity nodes and process data nodes linked by flows. These elements and their relationships drive the control flows and data flows within the context of spatial application logic. To maintain the validity and compatibility and prevent the incorrect information and process logic, integrity constraints of spatial processes are also discussed, in which spatial semantic constraints play the core role. As a result, spatial process modeling can be well standardized and supported. And workflow technologies can be integrated to manage and control complex GIS applications.; EI; 0; 6; 914-921; 40
