摘要
注记图层因为存储了文字的位置信息,且具有相对比例尺,字体大小可以相对变化,越来越多地被应用于GIS数据建库中。ArcGIS MDB坐标转换中,注记图层的处理不同于普通的点线面图层。本文详细讲述了"三规合一"数据坐标转换中注记图层的处理方法和过程,通过本方法进行处理,既省略了重建注记子类型分类的步骤,减少手工录入量,又保留了原有图层各属性字段内容,同时也保留了注记字体、大小、角度等相关显示信息,能最大限度保持原有注记显示效果。
Becase annotation layer stores location information of the text ,and has a relative scale led to the font size can be relatively change ,it is increasingly being applied to the GIS database building .In the ArcGIS MDB coordinate transformation,the processing of annotation layer is different from common point line surface layer .This paper elaborats the method of coordinate transformations for annotation layer data in “the complexities of urbanization”.The method can omit the steps of rebuild annotation classes and symbol collection ,reduce manual work ,and keep all attributes of original layer.Meanwhile,it can keep anntation's font,size,angle and other display infomation ,and so keep the original diplay effect to a large extent .
