摘要
地理信息系统(GIS)和遥感技术(RS)的一个重要发展趋势是两种学科的相互渗透和结合。文章从信息综合处理时效性的角度,提出了一种GIS、RS分布式多处理机综合处理系统模型,并进行了模型的系统设计。在此基础上,从GIS辅助遥感图象校正;RS自动生成数字高程模型(DEM),作为GIS的信息源;RS与GIS数据融合诸方面进行了综合技术处理实验。实验证明了该系统模型的合理性、可行性和时效性。
An important trend in the development of GIS and RS is their permeation and integration.So,based on the efficiency of the information comprehensive process,a GIS/RS comprehensive processing model of distributed multi-pro-cessing machines is presented,and the design of this system model is given in this paper.Additionally,GIS aided remote sensing image correction,data elevation model(DEM)which is produced automatically is used for a GIS data source and the fusion of RS and GIS data is processed in this comprehensive system.These experimental results are provided to show the rationalization and effectiveness of the proposed model.
