RS為基礎(chǔ)，談數(shù)字城市RGIS的發(fā)展
摘要 ：上海是我國(guó)長(zhǎng)江經(jīng)濟(jì)帶的龍頭和長(zhǎng)江三角洲的發(fā)展前緣，其區(qū)位的優(yōu)勢(shì)和快速的發(fā)展，對(duì)GIS信息庫(kù)的建設(shè)提出了特大城市化的要求。本文指出了如今GIS的誤區(qū)，即采用含有少量信息的地形圖作為GIS基本平臺(tái)。并提出了以RS信息為主的地理信息系統(tǒng)--RGIS，RGIS采用RS技術(shù)捕獲城市的面貌，直接以高分辨率的遙感影像作為GIS基礎(chǔ)平臺(tái)，建立一個(gè)大比例尺的航空與航天遙感信息場(chǎng)，使得城市管理者和建設(shè)者有一個(gè)能在計(jì)算機(jī)上就能看到全市綜合特征的信息庫(kù)，即綜合信息場(chǎng)。
RGIS不僅適用于上海這樣的特大城市，也適用于各省大、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
