航空摄影测量在地形数据修补测量中的应用——以文昌市航天核心区地形数据修补测量为例

Application of aerial photogrammetry in topographic data repair survey:Taking topographic data repair survey in the spaceflight core area in Wenchang City as an example

在城市管理及规划中,现有的测绘成果不能做到实时更新,难以满足实际工作需要。为提高地形数据的时效性、完整性和权威性,充分利用现有数据成果,对已有地形数据进行修测补测变得至关重要。本文以文昌市航天核心区地形数据修补测量为例,对航空摄影测量技术在地形数据修补测量中的方法进行研究,探索出一种能够满足日常地形数据修补测量的实际应用需求的技术方法。该技术方法能够满足日常地形数据修补测量的实际应用需求。

In urban management and planning,the existing surveying and mapping results can not be updated in real time to meet the needs of the actual work.In order to improve the timeliness,integrity and authority of the topographic data,and make full use of the existing data results,repair survey becomes crucial for the existing topographic data.Taking topographic data repair survey in the spaceflight core area in Wenchang City as an example,this paper studies the method of aerial photogrammetry in the repair survey,and explores a technical method that can meet the practical application requirements of daily repair survey.
