Abstract:
The performance of Web Geographic Information System(Web GIS) is not good when including mass of raster data, too many layers and spacial feature operations. This paper tests the Web GIS with different plans of database optimization and disk array, raster data’s compressing and pyramidal storage, layer’s amount and caches based on the ArcServer architecture of the ESRI company. Considering the enforceability in the real applications, it gives the optimization plans and analyzes the advantages and disadvantages.

摘要: 当前的网络地理信息系统(Web GIS)在遭遇影像数据、过多图层、大容量数据时的空间要素操作性能表现不佳。该文测试了基于ESRI公司ArcServer服务器架构的Web GIS系统在数据库优化与磁盘阵列、影像数据压缩与金字塔存储方案、图层数量、缓存机制等方面对系统性能的影响,结合在实际系统中的可实施性,给出相应的优化方案及利弊分析。
