Para garantizar la seguridad de dicho personal es necesario monitorizar la actividad volcánica ysísmica de manera continua con distintas tecnologías. Entre las tecnologías que se pueden utilizar se encuentran lastécnicas de Interferometría Diferencial SAR (DInSAR) para la detección de movimientos del terreno. Los movimientos enel terreno pueden tener distintos orígenes entre los cuales se encuentran los volcánicos y sísmicos. En esta investigaciónse van a analizar los movimientos que se han producido a lo largo de los años 2018, 2019 y 2020, detectados mediantetécnicas DInSAR y se intentará discriminar su origen. La detección mediante técnicas DInSAR se ha realizado conimágenes adquiridas por los satélites Sentinel 1A y Sentinel 1B durante los meses de diciembre a marzo de los años2018, 2019 y 2020. Se han utilizado técnicas DInSAR básicas con pares de imágenes. De todas las posiblescombinaciones de pares de imágenes se han seleccionado las que tenían mayores posibilidades a priori. Una vezseleccionadas las parejas de imágenes se han procesado utilizando como herramienta las aplicaciones SNAP (SentinelApplication Platform) y SNAPHU (Statistical-Cost Network-Flow Algorithm for Phase Unwrapping). Una vez obtenidos losmapas de deformaciones se han analizado los movimientos junto con otros datos de la isla como los mapas topográficos,geológicos, geomorfológicos, de pendientes y orientaciones con el propósito de encontrar explicación a cada uno de losmovimientos detectados y poder clasificarlos por su tipo de origen.","PeriodicalId":145404,"journal":{"name":"Proceedings - 3rd Congress in Geomatics Engineering - CIGeo","volume":"171 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121464569","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To reach this objective, an overview of the state of the art of ML isdone, visualising trends by science maps, based on bibliographic data of established research journals, found in GoogleScholar, Web of Science (WoS) and Scopus search engines. The bibliographic review carried out shows that the study ofML has traditionally been carried out with an ad hoc basis focused on the objective to be achieved, this aspect and otherknowledge gaps are discussed to analyse the global study of ML. Due to the broad spectrum of uses in which ML havebeen studied, the work has been focused on RS for monitoring and characterizing ML, focusing on two different aspects:(i) satellite monitoring of marginal lands; and (ii) determining carbon sequestration potential of marginal lands using remotesensing.","PeriodicalId":145404,"journal":{"name":"Proceedings - 3rd Congress in Geomatics Engineering - CIGeo","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128839539","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Como en la mayoría de las instalaciones urbanas, laubicación geográfica es un atributo clave en la gestión de las infraestructuras de iluminación urbana, y aunque el hardwarede alumbrado público basado en dispositivos IoT permite a los usuarios conectar múltiples sensores, los chips GNSS raravez se consideran en el diseño de hardware y software. En este trabajo presentamos el prototipo de un dispositivo deiluminación destinado a redes urbanas que permite geolocalizar farolas. El equipo de hardware consta de cuatro bloquesfundamentales: la placa BeagleBone Black (BBB), la placa eletrónica de gestión de la energía, la matriz de LED cableadosen serie y el bus de comunicación RS-485. Los bloques uno y dos forman un subsistema que denominamos sistema degestión de energía (EMS), mientras que el bloque cuatro es el responsable de la comunicación de bajo nivel con lossensores, en particular el sensor GNSS. Tras su integración en la red, nuestro dispositivo es considerado como un nodoen una estructura ramificada con tres niveles jerárquicos: el centro de mando, los nodos de control y las propias farolas;o en otras palabras, los grupos de nodos central, medio y periférico, respectivamente. La operación del procedimiento deposicionamiento es fundamentalmente autónoma, comenzando con la recolección de datos GNSS por el equipoelectrónico de la luminaria. Todos esos datos se envían al nivel superior para su posterior procesamiento en un entornoinformático diferente. Esta separación reduce los requisitos computacionales de los nodos terminales. Los nodos en elnivel 2 también son responsables de comunicar las actualizaciones de geolocalización a los nodos en el nivel 3, así comoal centro de mando en el nivel 1. Las tareas de comunicación se basan en solicitudes HTTP a través de líneas que vinculanlos tres niveles. Utilizamos la plataforma de código abierto Fiware, un marco diseñado para admitir soluciones inteligentes,que a su vez se basa en otros componentes de código bien conocidos como MongoDB, un sistema de base de datosNoSQL. Como resultado, tenemos un procedimiento de posicionamiento que puede integrarse en una red de iluminaciónque garantiza la eficiencia y otros requisitos en la actual gestión de la ciudad.","PeriodicalId":145404,"journal":{"name":"Proceedings - 3rd Congress in Geomatics Engineering - CIGeo","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124156265","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The ESFZ has been responsible for several shallow, destructive earthquakes in El Salvador, thus posing a seriousthreat for millions of inhabitants. Understanding its seismic potential and the behaviour of its different segments results ofgreat importance for the assessment and mitigation of seismic risk in the region. Geodetic techniques, such as GNSS andInSAR, are useful tools for measuring surface deformation related to tectonic activity. We are in the process of updatingand densifying the existing GNSS velocity field in El Salvador, aiming to characterise the individual faults in the region bydetermining their slip rates and locking depth. Additionally, we will process InSAR data, trying to obtain a continuousmeasurement of the interseismic deformation. The combination of this information with other data (e.g. seismological andgeological) through kinematic models will allow us to better understand the factors controlling the seismogenic behaviourof the ESFZ faults, evaluate their seismic potential and improve the seismic hazard assessment.","PeriodicalId":145404,"journal":{"name":"Proceedings - 3rd Congress in Geomatics Engineering - CIGeo","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132502004","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This multidisciplinary project aims to performspecific safety assessments using the SORA methodology adopted by the European Aviation Safety Agency (EASA) anddevelop documentation and procedures for operators to follow, complying with all required safety and regulatoryrequirements. As a result, DEURPAS-UPV is the first Spanish drone operator belonging to a university to be authorizedby Spanish civil aviation agency (AESA-Agencia Estatal de Seguridad Aérea), to perform drone flights in urban areas, incontrolled airspace and during the night. In addition, DEURPAS-UPV has performed the first authorized experimentaltransport operations using drones in Spain. The results from safety assessment and designed procedures have beensuccessfully applied to the operation of Safety and Emergency service providers, such as Valencia Local Police Corps andthe Valencian Emergency and Safety Response Agency (AVSRE - Agencia Valenciana de Seguridad y Respuesta a lasEmergencias). Overall, this project has served as an enabler for more complex and safer UAS operations, from theoperator’s point of view, which will help break the barriers related to the use of these aircraft, with huge potential ingeomatics applications.","PeriodicalId":145404,"journal":{"name":"Proceedings - 3rd Congress in Geomatics Engineering - CIGeo","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130566950","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In rainfed agricultural fields, erosion rates several orders ofmagnitude higher than the erosion rates considered tolerable have been quantified. In Mediterranean rainfed crops suchas vineyards, almonds and olive groves, and in the new sloping citrus and persimmon plantations, the rates of soil lossmake it necessary to apply measures to reduce them to avoid collapse in agricultural production. Managements such asweeds, catch crops and mulches (straw and pruning remains) are viable options to achieve sustainability. This work appliesmeasurements through plots, simulated rainfall experiments and ISUM (Improved Stock-Unearhing method) to quantifythe loss of soil at different temporal and spatial scales in fields of traditional management (herbicide or tillage) and underalternative management (mulches and plant covers). The work carried out at the experimental station for the study of soilerosion in the Sierra de Enguera and those of Montesa and Les Alcusses provide information on erosion plots undernatural rain. Experiments carried out with simulated rain in fields of olive, almond, citrus, persimmon, vineyard and fruittrees report the hydrological and erosive response under low frequency and high intensity rains. And finally, the ISUMtopographic method report the impact of long-term management, from the plantation. The results indicate that the loss ofsoil is greater (x10-1000) in soils under traditional management (tillage and herbicide) due to the fact that they remain barefor most of the year. The use of straw mulch immediately reduces soil erosion by two orders of magnitude. Also mulchesfrom chipped pruned branches remains are very efficient but require more years to reduce soil loss. Weeds and catchcrops are very efficient in controlling erosion.","PeriodicalId":145404,"journal":{"name":"Proceedings - 3rd Congress in Geomatics Engineering - CIGeo","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125146845","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

En Argentina, en la campaña agrícola 2017-2018, se destinaronmás de 200 millones de dólares para proteger los cultivos soja, maíz y trigo contra granizo. Luego de una tormenta, unperito visita el campo para estimar las mermas de rendimiento causadas por granizo, sin información previa de las regionesafectadas ni su intensidad. La precisión en la estimación del daño depende en gran medida de la identificación de ZonasHomogéneas de Daños (ZHD) dentro de la parcela para ponderar el daño total. Actualmente, las ZHD se delimitan acampo con técnicas visuales. Se propone desarrollar un algoritmo para definir las ZHD aplicando técnicas MachineLearning a índices de vegetación calculados con datos Sentinel 1 y 2. Se procesaron y compararon 5 índices demicroondas (DPDD, IDPDD, VDDPI, MPDI y DPSVI) y 5 espectrales (NDVI, EVI, SAVI, AVI y NPCRI) y se seleccionó elmás sensible a los cambios para cada tipo de señal; además, se incorporaron como variable de entrada al modelo lasderivadas de ambos índices. Para definir las clases se empleó K-Means (k = 3). Para validar el algoritmo se analizaron38 tormentas ocurridas entre los años 2017 y 2020 en 91 parcelas de soja, trigo y maíz ubicadas en la llanura pampeanaargentina. Se aplicó a cada parcela el modelo One-Way ANOVA (p <0.05). Los índices seleccionados fueron DPSVI yNPCRI. Se detectaron correctamente ZHD en un 66,67%, 78,13% y 72,70% de los casos analizados, para los cultivos demaíz, trigo y soja, respectivamente.

Advanced InSAR time series algorithms for monitoring and investigating surface displacement on Earth arebased on conventional radar interferometry. These techniques allow us to measure deformation with uncertainties of 1mm/year, interpreting time series of interferometric phases at coherent point scatterers (PS) without the need for humanor special equipment presence on the site. By applying InSAR processing techniques to a series of radar images over thesame region, it is possible to detect line-of-sight (LOS) displacements of infrastructures on the ground and therefore identifyabnormal or excessive movement indicating potential problems requiring detailed ground investigation. A major advantageof this technology is that a single radar image can cover a major area of up to 100 km by 100 km or more as, for example,Sentinel-1 C-band satellites data cover a 250 km wide swath. Therefore, all engineering infrastructures in the area, suchas dams, dikes, bridges, ports, etc. subject to terrain deformation by volcanos, landslides, subsidence due to groundwater,gas, or oil withdrawal could be monitored, reducing operating costs effectively. In this sense, the free and open accessCopernicus Sentinel-1 data with currently up to 6-days revisit time open new opportunities for a near real-time landmonitoring. In addition, the new generation of high-resolution radar imagery acquired by SAR sensors such as TerraSARX,COSMO-SkyMed, and PAZ, and the development of multi-interferogram techniques has enhanced our capabilities inrecent years in using InSAR as deformation monitoring tool. In this paper, we address the applicability of using spaceborneSAR sensors for monitoring infrastructures in geomatics engineering and present several cases studies carried out by ourgroup related to anthropogenic and natural hazards, as well as monitoring of critical infrastructures.","PeriodicalId":145404,"journal":{"name":"Proceedings - 3rd Congress in Geomatics Engineering - CIGeo","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117038731","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
