The Forestry Information Service Platform Based On Open Gis Environment

Modern forestry plays an important role in realizing ecological civilization, while basing forestry on information is the foundation and key guideline of modern foretry development. With basing forestry on information, building a forestry information service platform is regarded as a vital measure. Common pool in geodata is always a limitation to promote GIS, as well as to forestry GIS service platform. OpenGIS standard aims at settling the interoperation among special data in different sysytems and data structure.It is better to build a forestry information service platform on the foundation of open resource software. This software not only has the equal effect which dear business software has, but also saves money and has an extendibility in function. As PostGIS open resource database has a function which is no worse than any business software in managering and dealing with special data, it outlines in all of databases and is uesd into many programs along with good result. GeoServer is a server of special databases and has a function in publish data from many special databases and special data in many data format. What's more, it can take operation on data so that the limitation—unable to share information because of differing in structure—is removed. It is a key point to publish maps in GIS.This paper first describes the backgrounds of research project, status quo of domestic and international application research of forestry information services on the OpenGIS, then on the basis of full study on the theory of technology, including the theory and technology related OpenGIS, OpenGIS-based forestry information service platform, spatial database concepts, pre-process, digitization, storage and management the related spatial data; analysis and design the logical structure and function of the platform, The series follows the OpenGIS specification using open source software:open source database PostGIS, Database Server GeoServer, client-side open source software and spatial data processing middleware OpenLayer GeoTools, the platform based on J2EE framework for developing, implementing user management, data management, map data services, special system interface, comprehensive information dissemination and other functional modules.
