基于ArcObjects实现地图的散列式注记

Hash annotation based on ArcObjects

地图注记是描述地图属性信息的最主要方法之一,注记的质量与制图成果的质量密切相关。目前,各大GIS软件的注记类都是面向对象的,这种面向对象的地图注记库可以增强注记的编辑特性和地图数据复用性,但提供的注记类型过于单一,无法满足地图制图的要求。介绍ArcObjects开发技术,结合实际制图,二次开发实现散列式注记,从而完善ArcGIS中注记的实现方式,解决地图制图中注记的多样化需求。

Annotation is one of the most important methods to describe the attribute of map ,on which the quality of annotation is related to the quality of maps .At present ,the notes in GIS software are object‐oriented ,w hich can enhance the editing features and map data reuse ,but the annotation type is single ,and unable to meet the requirements of cartography .This paper introduces the ArcObjects development technology ,combined with the actual drawing and based on ArcObjects secondary development in order to improve the way of achieving note ArcGIS ,and solve the note of the diverse needs of cartography .
