基础GIS数据用于地质制图关键技术研究

Research on the key technology of geological mapping based on GIS data

近年来,随着电子地图技术的发展,在地质勘探中采用电子地图技术进行制图也越来越多。提出一种基础GIS数据用于地质制图的技术,主要从GIS数据模型中将道路、山脉、河流进行抽象建模,采用点、线、面结合的方式,用GIS数据表达地质结构情况。仿真实验表明,与传统的人工制图方法相比较,提出的基础GIS数据用于地质制图,提高了制图的准确度,在地质应用方面得到较大提升,具有较大的实用性。

In recent years,with the development of the electronic map technology,electronic map in the geological exploration technology is drawing more and more.Put forward a basic GIS data is applied to geological mapping technology,mainly from the GIS data model will be abstract modeling road,mountains,rivers,by means of dot,line,face combined with the GIS data to express the geological structure.Simulation experiments show that compared with the traditional manual mapping method,is put forward on the basis of GIS data for geological mapping,enhance the accuracy of the mapping,geological applications increase greatly,has great practicability.
