摘　　要：依据新疆高等级公路筑路材料的资源现状,采用叠置分析的地理信息系统(GIS)选线方法,研制开发了新疆高等级公路筑路材料GIS管理系统。将筑路材料资源信息及相关的地理背景信息按其数据特性的不同分为图形数据和属性数据两种,并以矢量数据及格栅数据两种结构形式进行表达;利用VB编程语言,基于OLE自动化技术对MapInfo进行二次开发,实现了Accsee数据与MapInfo数据的连接和GPS数据的输入。According to the distribution of materials for constructing highway in Xinjiang, this paper adopted the overlay GIS route selection method to develop the Xinjiang high-class highway material GIS management system. Based on the characteristics of the material resource information and the correlative geography background information, these two kinds of information were divided into graphic and attribute datum, and expressed by the vector data and the grill data. Using the VB programming language and the OLE automation technology, a second-round development from MapInfo was made to realize the connection between Access data and MapInfo data and the input of GPS data. 1 tab, 3 figs, 10 refs.
