1st Congress in Geomatics Engineering
Permanent URI for this collection
The 1st Congress in Geomatics Engineering aims to bring together scientists, academics and PhD students to exchange and share their results of research and innovation related to any Geomatics discipline. It offers a first-class interdisciplinary platform to present and discuss the innovations, trends, concerns, challenges and solutions adopted in the different fields of Geomatics. This biennial Congress is born within the framework provided by the Interuniversity PhD program in Geomatics Engineering by the Universidad Politécnica de Valencia and the Universidad Politécnica de Madrid.

- PublicationEstimación del riesgo sísmico en Castilla-La Mancha para la elaboración del plan especial de emergencias(Editorial Universitat Politècnica de València, 2017-10-23) Romero Jarén, Rocío; Quirós, Ligia; Sorondo, Fernando; Benito, Belén[EN] An estimation of the seismic risk in Castilla - La Mancha (Spain) is set forth in the current work, in order to develop the special emergency programme. To carry out the study it has been necessary to define a multidisciplinary group of experts in each involved discipline: geology and tectonics, seismology, architecture, engineering and geographical information systems. The main aim is to develop different seismic risk maps to provide the basis to elaborate the emergency plans in Castilla - La Mancha. These plans must follow the stipulated guidelines in the seismic risk field. A probabilistic methodology is adopted to define the seismic risk, considering this as the human and material losses in presence of the expected seismic event. The seismic hazard of the area of study is evaluated through return periods of 475 and 975 years, equivalents to exceedance probabilities of 10% and 5% in 50 years respectively. These probabilities are proposed in the framework of the Spanish seismic code “Normativa Sismorresistente Española, NCSE-02”, for conventional and special buildings. In a first approach, the study attempt to estimates the expected losses in each city of the overall of Castilla - La Mancha in the presence of the probable movements in 50 and 100 years. The results allow us to make a relative estimation of the seismic risk in different areas, identify those cities which undergo highest damages indexes and which ones would require a more in-depth assessment so as to mitigate the risk. Besides, the results contribute to establish objective priorities to define emergency plans at city scale.
- PublicationAnálisis de sismicidad asociada al llenado de embalses. Caso del centro de producción de Pirrís (Costa Rica)(Editorial Universitat Politècnica de València, 2017-10-23) Ruiz Barajas, Sandra; Alvarado, Guillermo E.; Benito Oterino, Belén; Climent, Álvaro[EN] The presented work is the result of a new collaboration between the Costa Rican Institute of Electricity (ICE) and the Technical University of Madrid (UPM) for the investigation of induced seismicity issues. Triggered seismicity associated with the filling of artificial water reservoirs is known since six decades ago. However, it is the case of triggered seismicity more complicated to model their effects. More than 100 cases of reservoir induced/triggered seismicity have been collected around the world and this issue continues today being a research topic of great importance. Indeed, new developments and contributions are constantly being made with the aim of achieve a better understanding of their characteristics and genesis. The main aim of the presented work is to analyze the spatial-temporal evolution of the seismic events recorded around the Pirrís reservoir before, during and after its filled. With the analysis of the seismic events we try to know and control the influence of the reservoir operations on the seismic activity of the area. Different parameters are studied, using methodologies proposed by different authors, in order to explain the possible effects of reservoir filling in changing the stress conditions in the environment and to detect any possible anomaly. Moreover, some analysis have been done in order to find a possible correlation between the water level in the reservoir and the evolution of the seismic activity recorded. Overall, the results of this study will provide important conclusions about the sensitivity of certain parameters to evaluate and model the effects of filling reservoirs on the seismic activity in the vicinity and we will present the spatial-temporal evolution of the seismicity associated with the specific case of the Pirrís hydraulic project.
- PublicationAplicaciones de los índices de fragmentación de los usos del suelo para caracterizar la expansión urbana(Editorial Universitat Politècnica de València, 2017-10-23) Sapena, Marta; Ruiz Fernández, Luis Ángel; Dpto. de Ingeniería Cartográfica Geodesia y Fotogrametría; Escuela Técnica Superior de Ingeniería Geodésica, Cartográfica y Topográfica; Grupo de Cartografía Geoambiental y Teledetección; Ministerio de Economía y Competitividad[EN] The growing number of people living in urban areas implies the need for more sustainable landscape management. The analysis and monitorization of urban areas allows for the quantification and characterization of urban sprawl processes. Currently, new geospatial and statistical databases are being developed in Europe (Urban Atlas and Urban Audit) with up-to-date and homogeneous information on urban areas, easing its comparison and monitorization, as well as the development of tools for computing urban fragmentation metrics by means of these data, such as IndiFrag. In this work, three applications of fragmentation metrics in multiple scales are presented. Firstly, an intra-urban analysis has been conducted by municipalities in Rome in two dates. Secondly, a massive analysis, comparing at the inter-urban level the fragmentation degree for one date and their growth patterns in a sample of 68 European urban areas. Finally, multiple regression models were tested to explore the prediction of socio-economic variables using the fragmentation metrics of the 68 urban areas. The outcomes show that fragmentation metrics for the analysis of morphology, composition, and urban growth, allow for quantifying urban sprawl patterns at intra- and inter-urban levels, facilitating its relation with socioeconomic variables.
- PublicationEPOS (European Plate Observation System)(Editorial Universitat Politècnica de València, 2017-10-23) Fernández, José; Gallart, Josep; Carbonell, Ramón; Díaz, Jordi; Villaseñor, Antonio; Azor, Antonio; Gonzalez-Matesanz, Francisco; Geyer, Adelina; Curto, Juan; Mattesini, Maurizio; Rodríguez-Fernández, Roberto; Fernández-Turiel, José; Ministerio de Economía y Competitividad[EN] EPOS (European Plate Observation System) (https://www.epos-ip.org/) is now established as the only European multidisciplinary and global research infrastructure in Earth Sciences. It integrates several hundred national observatories for the observation and measurement of the internal and dynamic structure of the planet, and in particular in Europe, distributed in 25 European countries, including Spain. The EPOS project, included in the 2008 ESFRI Roadmap, has been recognized by ESFRI in 2016 as a priority project for its implementation, because of its strategic relevance in the European Research Area.
- PublicationInfluencia del espectro sísmico en los efectos de los terremotos en las edificaciones(Editorial Universitat Politècnica de València, 2017-10-23) Navas Sánchez, Laura; Cervera Bravo, Jaime; Benito Oterino, Belén; Ministerio de Economía y Competitividad[EN] This project aims to analyse the influence that the response spectrum form may have in the damage that a building structure suffers. In order to demonstrate, two different buildings have been modelled: the first represents a typical construction situated in Lorca, which has a long fundamental period. And another which has a short fundamental period, whose singular design allows us to extract some conclusions about the influence of certain factors such as irregularities or torsion effects. Besides, it will be applied in both buildings two different seisms: a short and a long-period response spectrum, so as to study the resonance phenomenon. In addition, it will be exposed briefly the most important changes that have suffered the seismic codes according to the seismic design of building structures.
