| Summary: | Pipeline is a fundamental needs for distribution activities in the oil and gas industries. In the pipeline planning and construction, map is needed as a tool for selection of an optimal pipeline route and location. There are several methods that can be used for survey and mapping. Each methods has its own advantages and limitations. There are two methods performed in this research, namely UAV-based photogrammetry and terrestrial methods. Aerial surveys using photogrammetry techniques with an unmanned aircraft (UAV-based photogrammetry) can be used to deliver an alternative pipeline route. The camera used in this research is a non-metric camera. Non-metric cameras are not designed for measurement and mapping purposes. The imperfections of non-metric camera lens may affect the image quality and the geometric quality of the image. The aim of this research is to observe the UAV-based photogrammetry mapping results. Aerial images are processed into DSM, then filtered using SMRF and slope-based. The coordinates comparison of the final products, photogrammetric DTM and terrestrial DTM, are generated by using the terrestrial contour map as a reference. The average elevation values difference between the SMRF Agisoft 4B DTM and terrestrial DTM are 0.869 m, Slope-based Agisoft 4B DTM and terrestrial DTM are 0.639 m, SMRF Agisoft 12B DTM and terrestrial DTM are 0.861 m, Slope-based Agisoft 12B DTM and terrestrial DTM are 0.573 m, while LPS DTM and terrestrial DTM are 0.428 m. |
