Treatment and Analysis of the GNSS Signal from Smartphones and Its Applicability to Urban Mobility
Environmental Sciences Proceedings, 2023 High-precision GNSS algorithms have a complexity that requires a high computational load, so not all mobile devices will be capable of calculating position through their use, and without compromising their efficiency and wasting battery.

Tectonics, 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,

Tectonics, 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 ...

The 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 ...

Algorithms, 2023 This study describes a new algorithm developed to detect local cells of minimum or maximum heights in grid Digital Elevation Models (DEMs). DEMs have a low variance in digital levels due to the spatial continuity of the data. Traditional algorithms, such

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