10月15日，江西烟家山核电站项目筹备处召开江西烟家山核电站项目可行性研究阶段陆域地形测量项目成果评审会，江西省第一测绘院承担的地形测量成果通过专家评审。

　　专家组认为，项目施测的平面、高程基础控制网布设合理，网形强度高，点位分布均匀，密度满足要求。项目采用国家C级GPS点和国家I等水准点成果作为起算数据，科学可靠，各项观测记录数据齐全，数据处理、平差方法正确，施测要求、控制网平差后精度能满足要求。陆域1：1000、1：1万地形图数据采集、编辑成图方法正确，施测要素全面，图面表示合理，符号采用正确，数据格式、图廓整饰等符合“两纲”要求，1：2000、1：25000、1：5万缩编地形图各要素综合取舍恰当、合理，图式符号运用正确，符合要求。测量成果将根据专家组意见修改后提交业主。

October 15, Jiangxi smoke Jiashan nuclear power plant project to convene the Preparatory Office of Tobacco Jiashan nuclear power plant in Jiangxi project feasibility study stage of terrestrial topography assessment of the project results will, of Surveying and Mapping Institute of Jiangxi Province first topographic survey undertaken by the outcome of the assessment by experts.

The Group believes that the project facilities measuring plane, elevation control network laid the basis of a reasonable shape and high intensity, point and uniform distribution, density meet the requirements. Project uses the national C-GPS points and national level I and other outcomes as the starting point of the data, the scientific reliability of the observational record data is complete, data processing, adjustment method is correct, Shi measurement requirements, control network adjustment after the precision can meet the requirements. Landside 10000 1:1000,1:1 topographic map data acquisition, editing, mapping out properly, the elements of a comprehensive testing facilities, surface that is reasonable, using the correct symbols, data format, map profile finishing, which qualify for "two systems" requirements, 1:2000,1:25000,1:5 10000 topographic maps of various elements of downsizing the right to choose a comprehensive, rational and schematic symbols to use correct and meet the requirement. Survey results will be revised according to comments submitted by owners of the Group of Experts.
