WaterMap框架在水利信息化中的应用

The Application of WaterMap Framework in Water Informatization

GIS(地理信息系统)作为水利信息化中不可缺少的一部分,其开发效率和实现效果很大程度上决定了整个水利业务系统的成败。该文提出的WaterMap框架,贴合水利业务需求,对OpenLayers等底层库进行了封装,且在雨量专题展示、地图数据模型和数据可视化等方面做出了一定的创新,从而既显著提高了GIS的复用性和开发效率,也增强了地图操作的灵活性、提高了地图数据展示的多样性。通过在水利工程动态监管系统的实验,进一步验证了该框架的有效性和实用性。在当前业务数据大量积累、数据可视化展示需求日益凸显的情形下,可进一步推广应用。

As a significant part of water informatization,the efficiency and effect of GIS development is closely related to the performance of the water information system.The framework of WaterMap,as proposed in this paper,is built on the basis of OpenLayers catering to the necessity of water informatization.Besides,certain breakthrough is made on the aspects of precipitation display,spatial data model,and data visualization.Thus,it can be repetitively applied in different scenarios,help improve the efficiency of GIS development,and greatly improve the flexibility and variability of map operation.The framework is verified to be useful with the experiment of application in Dynamic Monitoring System for Water Projects.With the fast accumulation of spatial data and ever-increasing necessity of data visualization,it is suggested that the framework can be further applied.
