Abstract
This study aims to see the effect of non-metric oblique and vertical camera combination along with the configuration of the ground control points to improve the precision and accuracy in UAV-Photogrammetry project. The field observation method is used for data acquisition with aerial photographs and ground control points. All data are processed by digital photogrammetric process with some scenarios in camera combination and ground control point configuration. The model indicates that the value of precision and accuracy increases with the combination of oblique and vertical camera at all control point configuration. The best products of the UAV-Photogrammetry model are produced in the form of Digital Elevation Model (DEM) compared to the LiDAR DEM. Furthermore, DEM from UAV-Photogrammetry and LiDAR are used to define the fault plane by using cross-section on the model and interpretation to determine the point at the extreme height of terrain changes. The result of the defined fault planes indicate that two models do not show any significant difference.
Highlights
UAV-Photogrammetry (Unmanned Aerial Vehicle Photogrammetry) describes a photogrammetric measurement platform, which operates remotely controlled, semiautonomously, or autonomously, without a pilot sitting in the vehicle
The platform is equipped with a photogrammetric measurement system, including, but not limited to a small or medium size still-video or video camera, thermal or infrared camera systems, airborne LiDAR system, or a combination thereof. (Eisenbeiss, 2009)
UAV- Photogrammetry uses the nonmetric camera as the air photo acquisition instrument having the problem with instability of photography product geometric accuracy (Udin and Ahmad, 2012)

UAV- Photogrammetry uses the nonmetric camera as the air photo acquisition instrument having the problem with instability of photography product geometric accuracy (Udin and Ahmad, 2012). It is necessary to put oblique camera addition along with vertical camera in UAV-Photogrammetry. The Lembang Fault has considerable size and tremendous topography expression. This fault distance is only 15 km north of Bandung city and it is one of earth disaster sources in West Java. This fault distance is only 15 km north of Bandung city and it is one of earth disaster sources in West Java. (Horspool, et al 2011)
