卫星遥感、航空测绘、实地勘察……在外人看来，测绘工作应该充满了乐趣，甚至还有一些“刺激”。然而，走进测绘工作才发现，枯燥乏味，超负荷运转才是这个群体的主旋律。记者昨日从测绘部门了解到，经过专业人员夜以继日的努力，仅去年一年，市规划局测绘信息处就提供坐标转换20多轮次，总长度近2000公里；提供各种比例尺地形图和影像图面积约100平方公里，为南京市新测制地形图50平方公里。

　　一个普通的中秋节，一次家常便饭的加班，折射出了奉献精神。国庆前夕，住校的小宇早早回家，希望能和平时忙于测绘工作、连休息天都很少在家的父亲一起好好过个节。不料接连几天，父亲都行色匆匆，早出晚归。中秋节晚上，全家老小一直眼巴巴地在窗前等到半夜，楼梯间才传来父亲疲倦的脚步声。小宇忍不住数落起父亲来：“你成天在忙些什么？至于忙成这样吗？”是啊，工程紧张，测绘任务太重了。但父亲只是歉疚地笑笑，摸摸儿子的脑袋。

　　在刚刚过去的这个中秋夜，翘首期盼父亲回家团圆的岂止小宇一个人。在灯火通明的中央路、中山路道路整治出新工程现场，数十名测绘工作人员正加班加点，紧张忙碌着。这个小插曲不过是他们日常工作的真实写照。在城市快速发展时期，从事测绘工作注定要付出更多：休息、与家人团聚、进修、娱乐等都成了奢望，加班是家常便饭，抢工更是微不足道的寻常小事。

　　而测绘工作者紧张忙碌的身影又岂止出现在中央路这一处，又岂止是国庆节、中秋节。南京地铁二号线、南京禄口国际机场二期、南京南站、世纪金源、中山东路-汉中路整治出新……可以说，哪里有重点工程和重大项目，哪里就有测绘人员忘我的工作，就有优质、及时的测绘服务保障。仅以宁杭高铁、沪宁城际铁路、宁安铁路、京沪高铁和南京铁路南站等“四线一站”国家重点项目的测绘服务为例，据不完全统计，仅从去年以来，市规划局测绘信息处就提供坐标转换20多轮次，总长度近2000公里；提供各种比例尺地形图和影像图面积约100平方公里，新测制地形图50平方公里。这些枯燥的数字背后，凝结着无数测绘工作者夜以继日的超负荷工作和默默奉献。

　　为重点工程和重大项目提供测绘服务，主要包括测制、提供各类地形图、影像图成果，以及不同坐标系地形图数据之间的坐标转换，工作精度要求高，工艺十分复杂。仍然以“四线一站”项目的测绘服务为例，“四线一站”项目都是跨省的国家重点项目，任务要求急、责任重大，涉及政府决策、规划设计、项目施工等各个方面，数据转换不及时，就可能影响全线工程的顺利完成。由于工程涉及规划、设计、施工等多个环节，每个环节根据各自的特点，采用了不同的坐标系统和数据格式，不仅数据坐标转换难度大，而且线路变化大，转换轮次多，从规划到设计须多次对接，每一次都需要双向转换。

　　为强化服务，测绘信息处首先从重新编写、优化坐标转换程序着手，提高了坐标转换的精度和程序的适用性，大大降低了误差，满足了项目对坐标转换工作的需求。针对坐标转换的委托单位往往不是专业测绘人员，对自己使用的坐标系统的参数不了解的情况，测绘信息处加强沟通，变被动服务为主动服务，不厌其烦地一次次上门沟通、试验、检测，有时往往为确定一个参数就要往返多趟。与此同时，为提高服务效率，测绘信息处提出对所有工作环节实行急事急办，特事特办，确保渠道顺畅；作业人员随时候命，放弃休息，加班加点，用全方位的测绘服务为重点项目顺利进行提供了保障。

Satellite remote sensing, aerial mapping, site investigation ... ... In the eyes of outsiders, mapping work should be fun, and even some "stimulus." However, survey and mapping work into only found boring and overload is the main theme of this group. Reporter learned yesterday from the mapping departments, through the efforts of professionals, day and night, only last year, the Urban Planning Bureau of Survey and Mapping Information Service on the provision of coordinate conversion more than 20 rounds, with a total length of nearly 2,000 km; to provide a variety of scale topographic maps and image map an area of about 100 square kilometers, the new measurement system for the Nanjing topographic maps 50 square kilometers.

An ordinary Mid-Autumn Festival, a routine of overtime, which reflects the dedication. National Day eve Xiaoyu live at the school's early home, hoping, and usually busy mapping work, and even rest days are rarely at home with his father, had a good festival. Unexpectedly, after another few days, father, hurrying, morning to evening. Mid-Autumn evening, the family old and young have been eagerly waiting in the window at midnight, the stairwell was heard the footsteps of his father tired. Xiao-Yu could not help but chatter from his father to: "Are you busy all day what? As busy as it?" Yes ah, engineering stress, mapping the task too heavy. But his father is apologetic smile, touch his son's head.

In the past this in the autumn of looking forward to the reunion of the father to return home more than just Xiaoyu one person. In the brightly lit central road, mountain roads in a new renovation project site, dozens of surveying and mapping staff are working overtime, tension busy. This little episode is nothing but a true reflection of their daily work. Period of rapid development in the city engaged in surveying and mapping work is destined to pay more: rest, reunited with their families, education, entertainment, and so become a luxury, overtime is a common affliction, rob workers is insignificant trifling matter.

The surveying and mapping workers hectic figure not limited to the central road in the Office, but also more than just a National Day, Mid-Autumn Festival. Nanjing Metro Line 2 Nanjing Lukou International Airport, Nanjing South Station, Century Golden Resources, Zhongshan East Road - Hanzhong Road, renovation of new ... ... can be said that where there is major projects and major projects, where there are persons of ecstasy mapping work, there are high-quality and timely mapping service assurance. Ninghang only high-speed railway, Shanghai-Nanjing intercity railway, Ning Railway, Beijing-Shanghai high-speed railway and Nanjing South Railway Station and other "four-lane one-stop" national key projects of the mapping service, for example, according to incomplete statistics, only from the last year , the Urban Planning Bureau, Survey and Mapping Information Service on the provision of coordinate conversion more than 20 rounds, with a total length of nearly 2,000 km; to provide a variety of scale topographic maps and image map area of about 100 square kilometers, the new measurement system for topographic maps 50 square kilometers. These dry figures, the condensation of countless workers, day and night, the overload of surveying and mapping work and quiet dedication.

Key projects and major projects for the provision of mapping services, mainly including the measurement system, provide all kinds of topographic map, image map results, and the different topographic map coordinates of the coordinate conversion between the data, high precision work, the craft is very complicated. Continue to be "four-lane one-stop" project mapping service, for instance, "four-lane one-stop" project are the provinces of the national key projects, tasks demand a radical, heavy responsibility, involving government decision-making, planning and design, project construction and other aspects , data conversion is not timely, may affect the full range of projects successfully completed. As the project involves the planning, design, construction and many other links, each link in accordance with their characteristics, using different coordinate systems and data formats, not only is difficult to coordinate conversion of data, and the line changes, converting many rounds from the planning docking to the design to be repeated, each time require two-way conversion.

In order to strengthen services, Survey and Mapping Information Service beginning with rewriting, optimizing the coordinates of the conversion process to start with a coordinate transformation to improve the accuracy and applicability of procedures and greatly reduce the error, the project met the needs of the coordinate conversion. Commissioned for the coordinate transformation unit is often not a professional surveying and mapping personnel, for their own use of the coordinate system parameters do not understand the situation, Survey and Mapping Information Service to enhance communication, change from passive to active services, service, patiently again and again come to communicate, test, test, and sometimes To determine a parameter is often necessary to travel more times. At the same time, in order to improve service efficiency, Survey and Mapping Information Department on all aspects of the implementation of Jishijiban, handling the special matter, to ensure the smooth channel; operating personnel on standby to abandon rest, overtime, with a full range of surveying and mapping services for the smooth progress of key projects has provided a guarantee.
