摘要
地理信息系统(GIS)是地理学、地图学等在信息化时代发展的新的理论技术体系,其软件系统需要同时具有地理空间分析与地图表达两方面的功能。但是分析与制图对地理空间数据的要求存在一定程度的差异,导致两者间数据无法充分共享。在分析地理空间数据冲突的基础上,初步探讨了在GIS中实现分析与制图功能一体化的数据采集与应用方案,有助于避免数据的重复建设,提高地理空间数据的利用效率。
Geographic Information System （GIS） was a new theoretical and technical system of developing geography and cartography in information era. Its software needed in the meantime two aspects of function： geographic spatial analysis and cartographic expression. But there was a certain difference between spatial data of these two functions, which led to the data being not fully shared. Based on analyzing data confliction, this article basically discussed an integrative method of data collection and application in GIS which could avoid repeatedly building and increase using efficiency of geographic spatial data.
