ArcGIS-based data processing method for applications system of metro monitoring

摘要

Data processing is the foundation of subway construction monitoring system, it would be no practical significance leaving data. This paper taking the processing course of subway construction map for CAD format as an example, which is important while developing a subway monitoring application system, introduce the GIS-oriended data processing course, treatment methods, and key issues which should be noticed of the monitoring data from data collection to data storage and then propose specific methods for dealing with the problems.
