Data Center: GIS Function Warehouse

More and more organizations and departments need collaboration of geographic information function to complete work. The key is component reuse and collaboration in geographic information system (GIS) area. This paper adopts the component framework based on black box reuse, discusses the key technologies of function warehouse. Firstly, multi-granularity component structure is presented, including atom granularity, function component, function plug-in and function flow; Secondly, uniform function protocol is defined for unified management and release, unified configuration and system building on heterogeneous function resources. Through unified protocol, running service can discover and call function resource dynamically and achieve the function resource position and parameter transfer. Function warehouse can integrate various types of function resources, implement the uniform management and call in data center, and finally achieve collaboration of geographic information function with workflow engine and visual model building tools.
