| 摘 要： | 对利用1∶20000左右既有航摄资料采用全数字摄影测量系统测制1∶2000城郊规划用图进行探讨。作业中采用了相应的技术加强措施。测图工作结束后,又在测区进行了模拟导线和散点两种方法对图纸进行了高程、平面、精度的抽查,其结果表明,测图精度达到了预期值,满足了规划用图的需要。该方法可为今后一些局部地区急需用图,测绘作为借鉴。 |

| Abstract: | In this article, it introduces the making of 1:2000 suburban planning map with the existing 1:20000 aerial photo materials by VirtuoZo, the full digital photogrammeric system. During the processing, it uses the relevant techniques to ensure the quality. After the mapping, we make a spot check on the elevation, plane and precision to the map with two methods of the simulated lead-line and dispersed points. The result shows that the precision has met the expectation and also met the requirement of planning map. This kind of method can be used for the reference to the map making or surveying and mapping in the partial area with an urgent need in the future. |
