A Middleware-based Approach to Multi-source Spatial Data

摘要

With the progress of the data collection technology,available multi source spatial data is growing rapidly. Thecommon manners to access these data are limited by thecomplexity and the need to collect the data in a center location.Moreover, a variety of softwares adopts their own data formatswhich may not be understood by other systems, which makes thedata sharing difficult. Therefore, an approach to multi sourcespatial data is needed. This paper presents a multi source spatialdata sharing system based on the middleware technology and theOGC specifications. In this system, data applications interactwith a middleware component to derive data in the standardformats. The middleware component deal with distributed andheterogeneous data and it can be used by all the applications. Thesystem architecture, working principles, and detailed function ofeach component are introduced. Based on the research of thispaper, an integrated multi source spatial data sharing platformcan be developed with the middleware approach to the multisource spatial data.
