| 摘 要： | 随着信息技术的发展,地理信息的存储介质发生了很大变化,数字地形图作为计算机可识别存储介质上的有序集合,仍沿用最初的分幅方式。这种基于分幅、相互分离的数字地形图存在以下弊端:与无分割的实际地理空间实体不一致,无法适应地理信息的完整性需求;不便于数据库的分布式管理;地形图的叠幅使得信息重复获取与存储,产生裂隙和数据冗余,致使资源空间在使用上浪费。基于ArcGIS Engine9.2(相对于以前版本,功能大大得到扩展)的图幅自动化接边,可以实现数字地形图无缝拼接,解决了存在的弊端。 |

Algorithm Research for Automatic Edge Matching of Digital Maps Based on ArcGIS Engine 9.2 |

| Abstract: | The advantage of Geography information storage medium had very sweeping change along with the development of the information technology.The digital relief map as an aggregate could be distinguished by the computer,and continued to use the initial divide up way.These digital map's disadvantages which based on minute were as follow: It was inconsistent with the non-division actual geography space entity,also was unable to adapt the geography information demand completely.It was inconvenient to manage the database distribution.The repeatedly obtainment and storages of topographic fold characteristic caused the crevasse and the data redundancy.Using the automatic edge match of digital maps,matching the digital maps non-divisionally could be realized,these disadvantages could be improved. |
