基于AutoCAD二次开发实现库区淹没调查中图斑面积的统计与分类

摘要

基于AutoCAD平台二次开发，高效、准确地在数字化地形图中自动标注图斑号，并根据不同地类把各图斑分色填充图案，形成彩色分类图，同时把各图斑所在图幅号与图斑号相关联，自动生成图斑面积表和分类面积统计表等属性表，快速准确地完成库区淹没调查中图斑面积的统计与分类工作。%By secondary development based on AutoCAD platform, efficient, accurate and automatic coding of map-spots on digital topographic map is permissible; map-spots corresponding to different land-use classes are filled with different colors; drawing No. is associated with corresponding spot code; map-spots area chart and classified area statistics chart can be generated automatically, so as to permit rapid and correct map-spots area statistics and classification for reservoir area inundation investigation.
