近日,长城资源调查工作项目组组织专家在石家庄市召开《明长城测量项目》内蒙古自治区长城测量成果验收会。项目组认为,内蒙古自治区长城测量成果质量符合设计要求,一致同意通过验收。
该项目由内蒙古自治区测绘事业局统一组织,自治区航测院承担。共完成自治区境内明长城的210幅1:1万5米格网数字高程模型(DEM)、1米地面分辨率数字正射影像(DOM)、1:1万专题矢量数据、1:1万专题影像图数据(TMAP)、相关元数据,以及自治区明长城分布图、自治区明长城田野调查GPS轨迹图、自治区明长城测量加密分区方案图等。
为保证此项工作的顺利实施,自治区航测院多次与文物部门沟通,精益求精地处理每个长城要素。积极收集整合各种新资料,如地名库、公路图集等,努力提高成果的现势性。大力开展技术开发,经多次试验,解决了JX4 PBBA加密成果导入VirtuoZuo,VirtuoZuo AAT加密成果导入JX4的接口问题,组织人员编写入库程序,提高了入库的正确性和工作效率。
内蒙古明长城测量项目原计划生产1:1万图幅123幅,随着田野调查工作的开展,最终生产图幅210幅,测量单体、关堡及相关遗存1459个,工作量比原计划增加40%。工作区内明长城坡面长度712.572千米,投影长度706.421千米,测量的总体误差为0.028千米,测量成果质量得到项目组的好评。
Recently, the Great Wall of resources survey project team experts held in Shijiazhuang City, "Ming Great Wall of measurements," Measurement of the outcome of acceptance will be the Great Wall in Inner Mongolia. Project team believes that the Great Wall in Inner Mongolia measuring the quality of the results meet the design requirements, unanimously agreed to acceptance.
The project is the cause of Inner Mongolia Autonomous Region Bureau of Surveying and Mapping unified organization, autonomous regions and aerial hospital commitment. Completed within the Ming Great Wall in the autonomous region of 1:1 million, five MiG-210 network digital elevation model (DEM), 1-m ground resolution digital orthophotos (DOM), 1:1 million, thematic vector data, 1:1 million, thematic Image Map Data (TMAP), associated metadata, as well as maps of the Ming Great Wall and autonomous regions, autonomous regions and field research on the Ming Great Wall GPS track map, autonomous regions and the Ming Great Wall Survey map of encrypted partition scheme.
In order to ensure the smooth implementation of this work, autonomous regions and aerial hospital several times and heritage departments, excellence to handle each element of the Great Wall. Positive integration of a variety of new data collection, such as place names database, road atlas, and made efforts to improve the outcome of the current trend. Vigorously carry out technology development, after numerous tests, the results solved JX4 PBBA encryption into VirtuoZuo, VirtuoZuo AAT encryption results of the interface into JX4 organization to write storage procedures, improve the accuracy and efficiency of storage.
Ming Great Wall in Inner Mongolia measurements of the original plans to produce a 1:1 million map sheet 123, with the field surveys work, the final production map sheet 210, measuring monomer, off Castle and the remains of 1459-related work compared with the original plans to increase the 40%. Slope length of the Ming Great Wall of working area 712.572 km, 706.421 km projected length, measure the overall error of 0.028 km, measuring the quality of the outcome of the project team's praise.
