针对天津城市测量中建筑楼高测量存在的问题,本文提出一种基于C#辅助工具的建筑楼高测量新模式,给出了新模式的具体原理和实现流程。结合具体的工程项目,同时采用新旧两种楼高测量模式,比对两种模式下的测量结果和工作效率。工程实践结果表明:基于C#辅助工具的建筑楼高测量新模式是可行的,增强了结果的可靠性,提高了工作效率。 Aiming at the problems existing in building height measurement in Tianjin urban survey, this paper proposes a new model of building height measurement based on C # aids, and gives the specific principles and implementation process of the new model. Combined with specific projects, both the old and the new floor height measurement mode, the two modes of measurement results and work efficiency. The engineering practice shows that the new model of building height measurement based on C # aids is feasible, which enhances the reliability of results and improves the work efficiency.
