| 摘 要： | 数字地形图的接边问题实质是对两幅地形图的同步操作问题,提出长事务缓冲区同步接边法,以待接边边界为中心建立缓冲区,提取磁盘上另一幅地形图中落入缓冲区内的实体建立长事务,调入当前打开的地形图(当前数据库)中,实现了对两个待接边地形图的快速同步操作.用ObjectARX开发工具开发了在AutoCAD平台上执行的长事务缓冲区法接边程序,取得了满意的编辑效率和成图质量.

| Abstract: | The subsfance of digital topographical map join is the synchronous operation to two sheets of maps. A synchronous join method of long transaction in buffer area is discussed here, in which the join boundary is the center to establish buffer area and another sheet of map from disk is to be put into the buffer area, to reach a quick operation to two sheets of maps. By using ObjectArx SDK developed program running on AutoCAD environment, the software for synchronizing join method of long transaction in buffer area is designed, which satisfied with editing efficiency and drawing quality. |
