摘　　要：为有效显示各类测绘地理信息数据,达到数据快速浏览的目的,提出了一种分类别多尺度数据显示方法。基于数据显示库表,列明各类数据的数据格式、显示尺度、显示软件、显示符号等信息,生成显示配置文件;以配置文件为驱动、尺度为控制条件,快速显示各类多源测绘地理信息数据。通过在济南勘测资源一张图平台中的应用验证其实用性。In order to display all kinds of data and browse data quickly,the data display method based on multi-scale and classification is proposed.Based on the data display database table,the data format,display scale,display software,display symbols and other information of all kinds of data are listed,with configuration file as driver and scale as control condition,various kinds of multi-source surveying and geographic information data can be displayed quickly. Its effectiveness is verified by the application of Jinan survey resource one map platform.
