Ferrata 1, I-27100 Pavia, Italy; [email protected] (C.M.); [email protected] (C.P.); [email protected] (M.C.) * Correspondence: [email protected]; Tel.: +39-0382-985849 Received: 25 July 2018; Accepted: 7 August 2018; Published: 9 August 2018 Abstract: The deformation structures (folds and fractures) affecting Monte Antola flysch formation in the area of Ponte Organasco (Northern Apennines-Italy) were analyzed by Unmanned Aerial Vehicle Digital Photogrammetry (UAVDP). This technique allowed the realization of Digital Outcrop Models (DOMs) interpreted in a stereoscopic environment by collecting a large number of digital structural measures (strata, fractures and successively fold axes and axial planes). In particular, by UAVDP was possible to analyze the relationships between folds and fractures all along the study structures. The structural analysis revealed the presence of a series of NE-vergent folds characterized by a typical Apenninic trend and affected by four main sets of fractures. Fractures are always sub-orthogonal to the bedding, maintains constant angular relationships with the bedding and seems linked to the folding deformation. The study shows that the UAVDP technique can overcome the main limitations of field structural analysis such as the scarce presence and the inaccessibility (total or partial) of rock outcrops and allows for acquiring images of rock outcrops at a detailed scale from user-inaccessible positions and different points of view and analyze inaccessible parts of outcrops. Keywords: structural geology; Unmanned Aerial Vehicle; digital photogrammetry; remote sensing 1. Introduction In the last twenty years, the applications of remote sensing investigations for the construction of Digital Outcrop Models (DOMs) have rapidly increased in geosciences e.g., [1–11]. The most common techniques that are used to generate high detailed DOMs are Laser Scanner (LS) and Digital Photogrammetry (DP). Whereas LS could be very expensive and complex as for survey planning (heavy and bulky equipment), DP allows for obtaining high resolution data with a lower cost and a more user-friendly survey planning [7,12]. Developments in RGB cameras and Unmanned Aerial Vehicle (UAV) technologies [13] are quickly increasing the applications for UAV-based Digital Photogrammetry (UAVDP) in geosciences e.g., [7,9,14–18]. The field structural analysis could be often hampered by total or partial inaccessibility of rock outcrops [5] and by their unfavorable orientations [11] that do not permit acquiring an appreciable amount of structural data. Moreover, compass and clinometer field measurements of discontinuities could be affected by some biases (e.g., orientation and truncation biases) due to sampling techniques (e.g., scanline, window, etc.) or to the local variation in the orientation of measured features (e.g., waved/undulated surfaces). Sturzenegger and Stead [5] and Sturzenegger et al. [19] show how Digital Photogrammetry (DP) could help obtain more accurate parameters of position, orientation, length and curvature of discontinuity features. Tavani et al. [11] show how DP could help overcome limitations of structure exposure, giving the possibility to export orthorectified images of DOMs that Geosciences 2018, 8, 299; doi:10.3390/geosciences8080299 www.mdpi.com/journal/geosciences Geosciences 2018, 8, 299x FOR PEER REVIEW 22 o of f 16 16 limitations of structure exposure, giving the possibility to export orthorectified images of DOMs that well fit fit the orientationorientation ofof geologicalgeological structures.structures.

Sir Edmund Hillary With passion, patience and persistence… Abstract At the southern part of the Taupo Rift, crustal extension is accommodated by a combination of normal faults and dike intrusions, and the Tongariro Volcanic Centre coexists with faults from the Ruapehu and Tongariro grabens. This close coexistence and volcanic vent alignment parallel to the regional faults has always raised the question of their possible interaction. Further, many periods of high fault slip-rate seem to coincide with explosive volcanic eruptions. For some periods these coincidences are shown to be unrelated; however, it remains important to evaluate the potential link between them. In the Tongariro Graben, the geological extension was quantified and compared to the total geodetic extension, showing that 78 to 95% of the extension was accommodated by tectonic faults and only 5 to 22% by dike intrusions.

Laser scanning provides a dense point cloud that represents a precisely sampled replica of an object’s surface geometry. Integrating a digital camera into the scanning unit allows photographic images to be combined with these point clouds to produce interactive photo-realistic 3D models. The Differential Global Positioning System (DGPS) also built into the unit provides sub-metre global position information and allows data to be integrated with other georeferenced datasets.

OUTCROP EXPLORER: A POINT-BASED SYSTEM FOR VISUALIZATION AND INTERPRETATION OF LIDAR DIGITAL MODELS Gabriel Marx Bellina a Francisco Manoel Wohnrath Tognoli a,b Mauricio Roberto Veronez a,b a Graduate Program in Geology (PPGEO), University of Vale do Rio dos Sinos (UNISINOS). b Advanced Visualization Laboratory (VizLab), University of Vale do Rio dos Sinos (UNISINOS).

Phone: +55 51 3591 1122 [email protected] , [email protected], [email protected] ABSTRACT The use of LIDAR-based models for natural outcrops and surfaces studies has increased in the last few years. This technique has been found to be potential to represent digitally tridimensional data, thus it increases the quality and amount of data available for interpretation by geoscientists. Researchers, in computations, face difficulties in handling the huge amount of the data acquired by LIDAR systems. It is difficult to visualize efficiently the point cloud and convert it to high-quality digital models (DMs) with specific interpretation tools. Some in-house and commercial software solutions have been developed by some research groups and industries, respectively. However, all solutions must consider the large database as the pain point of the project. Outcrop Explorer has been developed to manage large point clouds, to provide interpretation tools, and to allow integration with other applications through data exporting. In terms of software architecture, view-dependent level of detail (LOD) and a hierarchical space-partitioning structure in the form of octree are integrated in order to optimize the data access and to promote a proper visualization and navigation in the DM.

Accelerometer, magnetometer, and gyroscope sensors integrated within consumer-grade smartphones can be used to record the orientation of images, which can be combined with location information provided by inbuilt global navigation satellite system (GNSS) sensors to geo-register the SfM-MVS model.
