A prototype for spatial information services based on J2EE
A prototype for spatial information services based on J2EE
摘要
Abstract
J2EE (Java 2 Platform , Enterprise Edition) is a kind of architecture that simplifies the development ,design and management of multilevel enterprise solution. The spatial middlewares based on J2EE can easily resolve the problems which the traditional Geographic Information Systems (GIS) now have to face with, such as transplantability,stability, easy maintainability and many more. This paper first introduces some conceptions and principles about J2EE, spatial middleware. then proposes a concrete J2EE-based solution of spatial middleware, namely SISP AS, which develops on JBoss(an open sources application server of J2EE) and uses the SISP spatial database. SISP AS follows Open GIS specifications, and implements a subset of OGC services. it improves interoperability and commonality by using XML/GML for communication and data transmission, resolves the transmission efficiency problem of large spatial data by using raster pyramid and vector pyramid. Finally, the related work will be presented. Notably,the experiments on this prototype system can proves that it is available to manage,distribute and share large scale spatial data by using SISP AS.关键词
