內政部國土測繪中心測量儀器校正實驗室發展簡介

Introduction to Survey Instrument Calibration Laboratory of National Land Surveying and Mapping Center

「工欲善其事，必先利其器」，測量儀器為執行測量業務主要之設備，若儀器本身存在有誤差，該項誤差便會傳播至觀測數據，影響測量成果，測量儀器應該定期校正，以確保測量成果品質。本中心從民國71年開始使用電子測距經緯儀辦理數值法地籍圖重測作業起，對儀器的校正即相當重視，在各項作業手冊均規定儀器應定期送校。本中心自81年起即在各測量隊建置簡易基線場辦理儀器校正作業，逐步開發校正系統，於95年建置電子測距固定基座基線場，進一步擴充測距儀器校正之作業能力及能量。96年3月國土測繪法公布後，更積極規劃測量儀器的校正系統，建置經緯儀校正場及衛星定位儀校正場， 97年成立「測量儀器校正實驗室」，發展符合國際認證規範ISO/IEC 17025 之品質管理系統，98年11月向TAF 提出校正實驗室認證申請，並於99年3月10 日通過TAF 校正實驗室認證。 Survey instrument is the main equipment to perform surveying work. Once the equipment isinaccurate, its error may severely affect the surveying results. All the surveying instruments shouldbe calibrated periodically to insure the quality of results. As early as 1982, the year that electronictheodolite was initially used to perform the said numerical cadastral map resurvey, the concept ofperiodical calibration for surveying instrument was put into related regulations. The simplecalibration sites were built up commencing the instrument calibration operation at each of thesubordinate survey teams of the National Land Surveying and Mapping Center (NLSC) in 1992. Theoperation details and procedures of instrument calibration were developed yearly. In 2006, theestablishment of pillar-base calibration site had more augmented the ability and capacity ofcalibration for distance measurement instrument thereafter. After the proclamation of the LandSurveying and Mapping Act in March 2007, establishments of angle measurement calibration systemand the system for GPS were then on projected to achieve. The Surveying Instrument Calibration Laboratory (SICL) was founded in 2008. A quality management system ofcalibration was then developed to meet the requirements of international certificationstandard ISO/IEC 17025. This laboratory has passed the recognition by TaiwanAccreditation Foundation (TAF) on March 10, 2010.
