ArcGIS Server应用开发中的数据优化策略

Strategy for Data Optimization in Application and Development of ArcGIS Server

影响ArcGIS Server应用系统性能的因素有很多,其中地图数据是关键因素之一。在ArcGIS Server应用于"长江流域水政执法卫星遥感动态监测系统"中,使用地图图层的整理、地图渲染、属性字段的整理、地图缓存机制等多种手段对地图数据进行了优化,从而大幅提高了系统中地图的访问速度。对如何进行数据优化作了详细介绍和讨论分析。

There are many factors affecting the ArcGIS Server system, therein, the map image itself is one of the key factors. In the ArcGIS Server System the Satellite Remote Sensing Dynamic Monitoring System for Marine Law Enforcement of Yangtze River Valley, map data are optimized by image layer arrangement, optimization of map rendering, field length arrangement, application of map cache mechanism and so on. Therefore, the access speed for maps in the system is increased greatly. In this paper, the methods for map data optimization are introduced in detail and then discussed.
