Abstract

Accurate elevation measurement is critical for applications such as construction engineering, land subsidence monitoring, and infrastructure management. Conventional terrestrial surveying using a Total Station provides reliable results but is labor intensive and time consuming. UAV-Photogrammetry offers a more efficient alternative by enabling rapid elevation estimation from aerial imagery acquired by camera equipped unmanned platforms. In this study, aerial photos were collected at three flight altitudes, 25 m, 35 m, and 45 m above ground level (AGL), and elevations derived from UAV-Photogrammetry processing were compared against Total Station measurements. The results demonstrate that imagery captured at 25 m AGL achieved the highest accuracy, with a Root Mean Square Error (RMSE) of 0.0313 m, followed by the 35 m AGL (RMSE = 0.0539 m) and 45 m AGL (RMSE = 0.1118 m). Statistical evaluation using a t-test indicated no significant differences between UAV-Photogrammetry elevations and those obtained from the Total Station.

Abstract

Topographic surveying in mining operations is used to determine the actual progress volume of excavated material. In open-pit mining, overburden volume can be estimated from Total Station survey data through surface-to-surface volume calculation and compared with production volume obtained from Truck Count data. This study evaluates weekly overburden volume estimates derived from Total Station survey data and compares them with Truck Count volume data. The results showed that the volume difference in Week 1 was -43.11 BCM with a deviation of -1.1%. In Week 2, the difference was +126.06 BCM with a deviation of +1.6%. In Week 3, the difference was -59.87 BCM with a deviation of -1.6%, while in Week 4, the difference was -112.97 BCM with a deviation of -1.1%. The total volume difference was -89.89 BCM, with an overall deviation of -0.4%. The paired t-test indicated no statistically significant difference between Total Station survey-based volume estimates and Truck Count data. Therefore, both approaches can be considered comparable for estimating weekly overburden volume in open-pit mining operations.
