Abstract

The invention relates to a geography information system (GIS) technology, in particular to a spatial information functional plug-in workflow construction method which comprises the steps that: Step (1) a database is connected and a data source is set; Step (2) a process template is created, process parameter information is added according to the factors of a process realization function, and the parameter information which is filled in is written into a workflow database table; Step (3) process parameters are defined for transmitting in and out parameters required by all functional nodes in a process; Step (4) a GIS workflow functional node is created, and the properties of the functional node are edited; Step (5) workflow starting and ending logic, activity execution logic and process control logic are defined; Step (6) the process parameters are edited and executed; and Step (7) the embodiment of workflow is debugged and operated according to workflow engine algorithm based on an activity state promoting model. The spatial information functional plug-in workflow construction method can support functional components in a GIS function library, so as to provide support for realizing visualized GIS functional modeling.

Description

technical field [0001] The present invention relates to workflow technology, and in particular to geographic information system technology (Geography Information System GIS), it is a kind of spatial information function plug-in workflow construction method. Background technique [0002] Workflow technology refers to a business process that is fully or partially supported or automatically processed by a computer. It was originally used for document management and office automation. With the continuous development of software platform technology, workflow technology has also continuously expanded its application fields. [0003] Many applications in GIS technology can be decomposed into functional processes for continuous execution, but the process control method and interpretation operation mode of the original office automation-oriented workflow management system cannot support the functional components in the GIS function library, and thus cannot realize visualization GIS ...
