為成果品質把關：地籍測量外業好幫手

辦理地籍測量工作時，電子測距經緯儀扮演相當重要的角色，舉凡圖根測量、界址測量及協助指界等主要工作項目，均必需使用電子測距經緯儀進行角度與距離觀測。早期外業測量所觀測資料係採用人工記簿方式，經內業整理後再輸入電腦計算，作業過程常發生觀測成果看錯、念錯、聽錯、寫錯或輸入錯誤等情形，致發生測量成果錯誤。為避免人為疏忽造成之錯誤、節省外業人工記簿及內業資料建檔時間，內政部國土測繪中心積極推動測量外業自動化系統，以提供於外業測量時，對觀測資料進行即時記錄、資料計算與檢核及點位顯示，提升測量外業效率，降低錯誤發生機率，確保測量成果零錯誤，以保障民眾土地產權。

During cadastral surveying work, electronic total stations play a significant role, as they are required for angle and distance observations in major tasks such as control surveying, boundary surveying, and assisting people in boundary identification.
The observation data in early field surveys was recorded manually and then inputted into a computer for calculations after being organized in the office. Errors such as misreading, mispronunciation, mishearing, incorrect writing, or input errors often occurred during the observation process, resulting in measurement errors.
In order to prevent errors caused by human negligence and to save time on manual field recording and data entry, the National Land Surveying and Mapping Center of the Ministry of the Interior actively promotes the Automated Survey System for field surveying. The system provides real-time data recording, calculation, verification, and point display during field surveying, which improves efficiency, reduces the likelihood of errors, and guarantees error-free measurement results, thereby protecting the people's rights and interests of land and property.
