摘要
地理信息系统(GIS)在组建和发展空间图形数据库中发挥着重要作用.GIS的核心是建立空间图形库与属性数据库的联动关系.在“辽宁省1/20万空间图形数据库”项目建库及系统结构设计中,利用国产GIS基础软件平台MAPGIS进行系统图层分类、数据输入和图形编辑,最终建立起空间图形数据库.利用GIS创建的空间图形数据库是进行其他地质研究的基础,可为下一步进行矿产预测提供多源图层及空间信息资料.GIS在矿产资源预测和其他地质领域,尤其是在区域地质调查、区域矿产资源与环境评价、矿产资源与矿权管理中也将发挥越来越重要的作用.
Geographic information system(GIS) plays an important role in forming and developing spatial databases.The core of GIS is to establish an interactive relationship between the spatial graph database and the attribution database.In the project of creating the 1:200 000 Spatial Graph Database of Liaoning Province,the software platform — MAPGIS,developed by China University of Geosciences — is based on to sort system graph layers,input data and edit graphs.The GIS based spatial graph database is a basis for geological research.It may provide multi sourced graph layers and spatial information for mineral resources forecasting,as well as for regional geological surveying,assessment of regional minerals and environment,administration of resources and the rights of mining.
