天地图山东影像缓存方法研究与实现

Study and Implementation on the method for Image Cache of Tianditu in Shandong Province

摘要:

以山东省地理信息公共服务平台为例，阐述了从获取成品分幅影像到瓦片更新至系统的工作流程以及产生的成果。主要成果包括影像自动分块程序、电子地图数据的解密软件、缓存数据检查程序等工作中开发的工具。在实际工作中从数据处理的实际需求为出发点，进行程序开发，将数据处理和程序无缝结合，能充分发挥程序的效率，通过对一系列程序的应用，显著提高了工作效率，对相关数据处理人员有借鉴意义。

Abstract:

Taking Shandong Common Platform of Geo-spatial Service as an example，workflow and production results on how to update the image cache of finished image products to the system have been illustrated. Main achievements include the image automatically block programs, digital map data encryption software and checker of image cache. Taking processing data in the practical work as a starting point, program development has been carried out. It can give full play to the efficiency of procedures, and improve work efficiency. It will provide some references in the data processing.
