测量标志现状分析及保护措施

Analysis of the status and protection methods of survey marks

测量标志作为测绘地理信息数据的基础、为城市建设和发展提供重要的空间位置基准信息,然而城市的扩张、重建、规划也导致了测量标志大量损毁,为此,本文将根据某地区测量标志点的核查结果,从测量标志点的等级、埋设年份、所处地类、保护装置、点类型5个方面对测量标志损毁情况进行分析。通过实例分析,证明了测量标志的损毁情况与其核查维护、埋设年份、所处地类等有关,与点类型无明显关系,并根据分析结果对当地测量标志保护提出了合理建议。

As the basis of surveying and mapping geographic information data,survey marks provide important spatial position reference information for urban construction and development.However,urban expansion,reconstruction,and planning have also led to a large number of damage to survey marks.For this reason,the damage of the mark points were analyzed from five aspects:the level of the measuring mark point,the year of burying,the type of location,the protection device,and the point type.Through an example analysis,it was proved that the damage of the survey mark was related to its inspection and maintenance,the year of burial,and the type of place where it was located,but has no obvious relationship with the point type.Based on the analysis results,reasonable suggestions for the protection of the local survey mark were put forward.
