Research andDesign onaWeb-Based System forSpatial DataCo-Edit

Web-Based System forSpatial DataCo-Edit isa CoGISsystem, andalsoa WebGISapplication system. This paperstudies thetechnical schema forGML-Based WebGISapplication systemusedJ2EE systematic framework. A Geography MarkupLanguage (GML)and J2EEbasedWebGISmodelisprovided. A task-group managementmechanism for CoGIS is designed. Meanwhile, acontrol system forspatial dataco-edit is provided. Thissystem isanasynchronous concurrent mechanism system usesedition management methodto co-edit. Thissystem hasbeenimplemented whichsolves theshareofheterogeneous spatial dataandco-edit efficaciously.
