| 摘 要： | 管网GIS中大量的管井点状符号的绘制，采用外业全站仪数值编码与属性编码相结合，内业通过CASS与Offiee Excel软件进行数据预处理，在CASS软件中对所有的管井用任意一种点样式替换原有的管井图形块，将CASS数据导入到MapInfo中后直接用规定的管井点样式替换缺省点样式的方法，为GIS数据的预处理节省了宝贵的时间。

| Abstract: | When drawing the numerous point shape marks of tube wells in pipe network GIS, entire station instrument value codes can be combined with attribute codes when outdoors work is being done, and the data can be pretreated by using CASS and Office Excel in the office. Then in CASS, the orginal tube well graph block is replaced with any kind of spot style in all tube wells;finally,the CASS data is inducted into MapInfo and the omitted spot style is replaced with the fixed tube well spot style directly. Thus, by this way, a lot of precious time can be saved for GIS data pretreatment. |
