摘要
现代城市的规划、决策和资源利用离不开地理空间数据库的支持,而工程测量图是地理空间数据建库的重要数据源。本文研究了由欧特克计算机辅助设计(CAD)工程图构建SuperMap空间数据库的基本方法,通过图纸预处理、数据读取与转换、数据检查与修复等过程,建立了一个案例地理空间数据库,并实现了某城区地理空间数据的可视化分析与应用。
The planning,decision-making and resource utilization of modern cities are inseparable from the support of geospatial database,and engineering survey map is an important data source for geospatial data database construction.This paper studied the basic method of constructing SuperMap spatial database by CAD engineering drawings.Through the process of drawing preprocessing,data reading and conversion,data checking and repairing,a case geospatial database was established,and the visualization analysis and application of geospatial data in a city were realized.
