摘要
GIS空间数据的出版可视化技术研究与实践,不仅能够满足GIS空间数据的出版要求,同时对于最大限度地利用GIS数据资源、避免基础数据的重复投入和提高地图生产效率有着重要的现实意义。文章论述了地理空间数据的类型、关系、矢量数据结构及其在电子出版系统中共享的制约因素,讨论了GIS空间数据在电子出版系统中可视化技术实现的基本方法,在实践的基础上提出了两种企业级解决方案。
Research and practice on publishing and visualization technology of GI S data have important practical significance not only in to meet the needs of GIS spatial data publishing,but also in the full play of GIS data resources utili zation,to avoid unnecessary basic data repetition and to raise map productive e fficiency.The paper discusses type and relation of geo-graphic spatial data,v ector data structure and its condition of sharing in electronic publishing.It a lso discusses basic method of realization of GIS spatial data visualization in e lectronic publishing system,put forward two enterprise level resolvents on th e practical basis.
