RS为基础，谈数字城市RGIS的发展
摘要 ：上海是我国长江经济带的龙头和长江三角洲的发展前缘，其区位的优势和快速的发展，对GIS信息库的建设提出了特大城市化的要求。本文指出了如今GIS的误区，即采用含有少量信息的地形图作为GIS基本平台。并提出了以RS信息为主的地理信息系统--RGIS，RGIS采用RS技术捕获城市的面貌，直接以高分辨率的遥感影像作为GIS基础平台，建立一个大比例尺的航空与航天遥感信息场，使得城市管理者和建设者有一个能在计算机上就能看到全市综合特征的信息库，即综合信息场。
RGIS不仅适用于上海这样的特大城市，也适用于各省大、中、小城市。

Abstract:
Shanghai is the center of the Yangtse River Economic Area and the developing front line
of the Yangtse Delta. Her area advantage and accelerating changes require metropolitan
information for the GIS database construction.
This paper points out the GIS common failing of using topographic maps with little
information and suggests RGIS in which RS information is the main content. It catches the
general view of the whole city by RS technology and takes high resolution RS Images as
GIS basic platform directly. It builds up a large-scale aviation RS&n
