Insights of Active Extension Within a Collisional Orogen From GNSS (Central Betic Cordillera, S Spain)

open access: yesTectonics, Volume 42, Issue 7, July 2023., 2023
Abstract The coexistence of shortening and extensional tectonic regimes is a common feature in orogenic belts. The westernmost end of the Western Mediterranean is an area undergoing shortening related to the 5 mm/yr NNW‒SSE convergence of the Nubia and Eurasia Plates. In this region, the Central Betic Cordillera shows a regional ENE‒WSW extension. Here,

The Role of Faults as Barriers in Confined Seismic Sequences: 2021 Seismicity in the Granada Basin (Betic Cordillera)

open access: yesTectonics, Volume 41, Issue 9, September 2022., 2022
Abstract Fault barriers are key structures for studying seismic hazard in regions of intense brittle deformation. The interaction between fault sets affects their seismogenic behavior, if some of them act as barriers. The Granada Basin, in the Betic Cordillera, is a region affected by shallow brittle deformation, as it was the scenario for the recent ...

Deflection of Vertical Effect on Direct Georeferencing in Aerial Mobile Mapping Systems: A Case Study in Sweden

open access: yesThe Photogrammetric Record, Volume 37, Issue 179, Page 285-305, September 2022., 2022
This paper aims to study and quantify the induced error due to the deflection of verticals (DOV) when integrating different sensors, focusing on GNSS and INS for 3D mapping in airborne mapping. It is shown that the DOV effect should be considered for direct georeferencing because the DOV components are in the order of (or larger than) INS uncertainty ...

Thematic quality assessment of land surface geospatial data based on confusion matrices: A matrix set for research on measures and procedures

open access: yesGeoscience Data Journal, Volume 9, Issue 1, Page 37-45, June 2022., 2022
Entity‐relationship diagram (ERD) of the confusion matrix dataset. Abstract The confusion matrix has long been adopted as the ‘de facto’ and ‘de jure’ standard method of reporting on the thematic accuracy assessment of any land surface geospatial dataset.

Relative Radiometric Normalisation of Unmanned Aerial Vehicle Photogrammetry‐based RGB Orthomosaics

open access: yesThe Photogrammetric Record, Volume 37, Issue 178, Page 228-247, June 2022., 2022
This article deals with the problem of varied brightness of UAV images caused by the changing weather conditions. Relative radiometric normalization (RRN) of acquired RGB imagery is used to improve the visual quality of the resultant orthomosaic. The algorithm utilizes image positions and their relationships to group them, choose references, and ...

High‐ and Low‐Angle Normal Fault Activity in a Collisional Orogen: The Northeastern Granada Basin (Betic Cordillera)

open access: yesTectonics, Volume 40, Issue 7, July 2021., 2021
Abstract Understanding active tectonics and seismicity in extensional settings requires the analysis of high‐angle normal faults (HANFs) and the transfer of deformation at depth. The debate surrounds the role of low‐angle normal faults (LANFs) in triggering high magnitude earthquakes.
