An Automatic Rapid Annotation Placement Algorithm of Point Features Based on Template

摘要

This paper first discusses the necessity of the automatic annotation placement.According to the Chinese custom of reading map,based on the present principle of map annotation placement,a new principle is proposed.Then some present algorithms of automatic map annotation placement are introduced and,at the same time,their shortcomings are pointed out.In order to improve the automatic annotation placement,the authors bring forward an automatic annotation placement algorithm of point feature based on template.The template is explained and described by figures.Then the automatic placement process using the template algorithm is detailed.At last,this paper shows the experimental result based on the new algorithm and makes some useful conclusions.
