摘要
通过研究地理信息系统软件实现推荐航线的规划和海图专题图制作的方法,基于ArcGIS软件完成在不同比例尺海图基础上的航线数据采集及规划,利用COGO功能模块完成航向、航程等专题信息数据获取;使用字段计算功能和编写脚本程序完成智能化注记,实现专题信息的制图表达。实际应用表明,该方法能高效完成航线规划,提高制图效率。
The paper mainly makes research on the methods of GIS software to achieve recommended route planning and chart thematic mapping,specifically refers to the use of ArcGIS software to complete the route data acquisition and planning based on different scale charts,and to extract the thematic information such as direction,distance and other topics via the COGO function module,use field calculations and scripting to implement intelligent labeling and thematic information express on mapping.The practical application shows that this method can complete route planning efficiently,and improves the efficiency of mapping.
