Abstract

The invention relates to a construction method for geospatial information workflow service function flow templates. The method is characterized in that a framework is constructed on the basis of a service function flow template of a spatial function warehouse architecture, and by sufficiently utilizing the advantages of scalability and easy construction of the spatial function warehouse, the rapid extension and packaging of spatial function services is provided. The core component of the framework mainly comprises two parts, i.e. a function drive service module and a service function flow execution engine. The function drive service function for driving services serves which serves as an important part of the function warehouse of a geospatial information kernel provides a function of discovering and registering various heterogeneous GIS (Geographic Information System) function component resources on spatial information nodes, and after the warehouse registration and clearing of the function components, all the issued functional resources declare resource services to the outside according to a unified interface specification. The service function flow execution engine which serves as a carrier for the logic execution of the lower-layer functions of the spatial information grid services can instantiate a service function processing flow by parsing service flow templates in a service function flow template library and call and execute a function drive service for a spatial function component associated with a function flow object.

Description

technical field

[0001] The invention relates to a method for constructing a geographic spatial information workflow service function flow template. Background technique

[0002] Industry or field-oriented remote sensing information tools, advanced geospatial information and professional tools often involve complex processing models or processes. In order to reduce the difficulty of building models for users and make full use of existing tool models, existing tools can For construction and reuse, this project needs to provide a visual modeling environment, that is, a new application tool technology that uses basic tools to describe and build new application tools in a graphical way.

[0003] Geographic information system software can be divided into two categories of functional blocks: spatial data management and spatial analysis and processing in terms of architecture. Spatial data management is usually completed by spatial data map and spatial data engine, which realizes t...
