建築基地斷面高程測量，目前在UAV、GNSS、GIS的新科技成熟運用下，也不可避免使用新科技並更靈活運用，讓基地斷面高程測量工作節省人力、物力、時間與成本，而如何有效將傳統測量與現代科技結合做最佳使用，也是現今測量工作共同目標。目前斷面高程測量作業經常使用儀器有全測站電子經緯儀、電子水準儀、GNSS接收儀，而由主管測量機關地政司、國土測繪中心提供控制點資料做為依據、再解算GNSS接收資料，為國家統一之坐標、高程，兩者資料做最佳組合;而現今基地測量皆常運用UAV拍攝影像，並配合相關繪圖軟體計算斷面高程精度亦已提高，故本論文以建築基地斷面高程為探討範疇，探討目前是否UAV產製成果可替代以往地形測量(全測站電子光波經緯儀)所計算之斷面高程，本次論文研討範圍以建築基地斷面高程進行比較。
影響無人機航拍因素與精度有很多，例如空域、飛行限制、證照、無人機的型號和設備、地面控制點、天氣情況、樹木覆蓋率、水體等等。 因此，在進行無人機航拍之前，規劃設計是必不可少的。而全測站儀器觀測資料，亦受到使用儀器精度、觀測點位數量、測量人員經驗、天氣情況等等影響，故針對兩種測量方式進行比對。
全測站觀測的坐標、高程資料，為測點之坐標、高程資料組成三角網(TIN)，由點轉成面。而UAV航測資料係運用相片重疊產製DSM，兩種3D模型比對斷面高程差異。
UAV航拍完成後，運用地面控制點不同位置、數量的約制比對其精度，並與全測站儀器觀測資料加以比對，求得最佳方式及其影響狀況。最後分析使用無人機計算斷面高程具有的優勢和潛力。

Geographic Information Systems (GIS), incorporating new technologies into building site section elevation measurements has become essential to optimize resources, time, and costs. The integration of traditional surveying methods with modern technologies is a crucial task in surveying work. This study explores the potential of using UAV-based methods to replace traditional terrain measurements (total stations and electronic theodolites) for calculating section elevations, focusing on comparing the accuracy of both methods.
The paper first discusses the instruments commonly used for section elevation measurements, including total stations, electronic theodolites, and GNSS receivers. Control point data from supervising surveying agencies are used as references, with GNSS receiver data reprocessed to obtain unified national coordinates and elevations, achieving an optimal combination of datasets.
Factors influencing the accuracy of UAV aerial photography, such as airspace, flight restrictions, licenses, UAV models, equipment, ground control points, weather conditions, tree cover, and water bodies, are thoroughly examined, emphasizing the importance of planning and design before conducting UAV aerial photography. Similarly, the observed data from total station instruments are impacted by instrument accuracy, number of observation points, surveyors' experience, weather conditions, and other factors.
The coordinates and elevation data obtained from the total station form a triangulated irregular network (TIN), while UAV aerial survey data generates a digital surface model (DSM) through photo overlapping. These two 3D models are compared to analyze differences in section elevations.
To verify the accuracy of UAV aerial photography, ground control points in different positions and quantities are used, and results are compared with observed data from the total station instrument to determine the optimal method and its impact. The advantages and potential of using UAVs to calculate section elevations are then carefully analyzed.
In conclusion, this research demonstrates the potential of UAV-based methods as a viable alternative to traditional terrain measurements for section elevation calculations. It sheds light on the importance of integrating modern technologies with conventional surveying methods to enhance accuracy and efficiency in building site section elevation measurements.
