Abstract

This study analysed and compared the accuracy of the results of Sentinel 1A satellite image processing in the ascending and descending orbit directions with SNAP software. The research is located at Tukul Dam, Karanggede Village, Arjosari District, Pacitan Regency, East Java Province, with a range of observation data for one year in 2022-2023. Sentinel 1A satellite image processing uses the Differential Interferometry Synthetic Aperture Radar (DInSAR) method. The results of Sentinel 1A image processing were validated using measurement data from 38 dam surface measurement points that had been measured terrestrial. The accuracy calculation uses the Root Mean Square error (RMSe) to measure the vertical movement of coordinates (Z) from the results of Sentinel 1A image processing in the ascending and descending orbit directions with the actual position in the field measured terrestrially. The result is the RMSe value of vertical movement from the Sentinel 1A image processing in the ascending direction is 0.015m. In comparison, the result of Sentinel lA image processing in the descending orbit direction is 0.234m. Based on the calculation results of the RMSe value of vertical movement, the results of Sentinel 1A image processing in the ascending direction are better used for calculating vertical movement at Tukul Dam.

Abstract

The advancement of geospatial technology has enabled various methods to produce high-accuracy Digital Terrain Models (DTMs), including Terrestrial Laser Scanning (TLS). This study evaluates the accuracy of TLS-derived DTMs in areas with varying topography at Universitas Diponegoro, Semarang. Data collection involved TLS, Total Station, and Leveling for georeferencing and accuracy assessment. The analysis included DTM visualization, RMSEz and LE90 calculations, and paired t-tests. Results show the TLS-derived DTM meets Class 1 accuracy standards for a 1:1000 map scale. Visualization demonstrated TLS's ability to represent both steep and flat terrain in detail, including contours and breaklines. The statistical test yielded a p-value of 0.710, indicating no significant difference between TLS and terrestrial data. The evaluated accuracy metrics are essential for assessing the reliability of TLS in real-world mapping. The results confirm TLS's capability to produce consistent and detailed terrain models, supporting its use in high-precision spatial applications such as infrastructure planning, environmental monitoring, and disaster mitigation. Therefore, TLS is a reliable method for generating high-quality DTMs across diverse topographic conditions.
