6月18日，国家测绘地理信息局在中国测绘创新基地主持召开了验收会，对由中国测绘科学研究院国家光电测距仪检测中心牵头、陕西测绘地理信息局第一测绘工程院参与承担的“全国比长基线场检定项目”进行验收。

该项目首次对传统的24米因瓦基线尺方法与现代高精度全站仪测距量值在全国测绘地理信息行业范围内，实施了为期长达四年的比对研究，在客观地评价传统方法、替代方案和与国际接轨等方面进行了有益的探索，取得了有价值的建设性和前瞻性研究成果。

以陈俊勇院士为组长的专家组对项目成果给予了高度评价，陈院士强调，测绘仪器量值的准确和统一是《测绘法》对测绘基准的基本要求和保证测绘成果质量的前提，建议后续设立专项，加强测绘计量基础研究。

国家测绘地理信息局副局长李维森指出，通过计量检测对测绘仪器装备质量实施客观和科学的评价，是测绘成果质量最重要的决定性环节之一。测绘新技术不断涌现，作为测绘仪器装备的计量检测应跟上技术发展步伐，加大公益性的科研投入力度，为现代测绘地理信息产业化的发展提供更强有力的基础技术保障。

In June 18th, the State Bureau of Surveying and mapping geographic information inChina innovation base mapping chaired the acceptance, acceptance of the lead, by the state Chinese Academy of Surveying and mapping the geodimeter testing center of Shaanxi surveying and Mapping Bureau of Surveying and Mapping Engineering Institute of geographic information first commitment to participate in the"national than long baseline field test project".

The project for the first time on the traditional 24 meters invar baseline rulermethod and modern high-precision total station location value in national mapping and geographic information industry scope, carried out comparison study for a period of up to four years, in the objective evaluation of the traditional methods,alternatives and in line with international standards and other aspects of a useful exploration, has achieved a the value of constructive and forward-looking research.

In order to academician Chen Junyong as leader of the expert group gave a high evaluation of project results, Chen emphasized, instrument of Surveying and mapping data accuracy and unification is the "basic requirements for surveying and Mapping Surveying and Mapping Law" and the premise of quality surveying and mapping results, suggestions for the establishment of a special, strengthen basic research on drawing measurement test.

Deputy director of the State Bureau of Surveying and mapping geographic information Li Weisen points out, by measuring the implementation evaluation of objective and scientific instrument equipment quality of Surveying and mapping,surveying and mapping results of quality is the decisive link in one of the most important. The new survey technology continue to emerge, as the measuringinstrument of Surveying and mapping equipment should keep up with the pace oftechnology development, increase the public welfare research investment, provide basic technical support more powerful for the development of modern surveying and mapping geographic information industrialization.
