Hybrid Methodological Evaluation Using UAV/Satellite Information for the Monitoring of Super-Intensive Olive Groves Esther Alfonso, Serafín López-Cuervo, Julián Aguirre, Enrique Pérez-Martín, Iñigo Molina Applied Sciences Switzerland, 2025 Advances in Earth observation technology using multispectral imagery from satellite Earth observation systems and sensors mounted on unmanned aerial vehicles (UAVs) are enabling more accurate crop monitoring. These images, once processed, facilitate the analysis of crop health by enabling the study of crop vigour, the calculation of biomass indices, and the continuous temporal monitoring using vegetation indices (VIs). These indicators allow for the identification of diseases, pests, or water stress, among others. This study compares images acquired with the Altum PT sensor (UAV) and Super Dove (satellite) to evaluate their ability to detect specific problems in super-intensive olive groves at two critical times: January, during pruning, and April, at the beginning of fruit development. Four different VIs were used, and multispectral maps were generated for each: the Normalized Difference Vegetation Index (NDVI), the Green Normalized Difference Vegetation Index (GNDVI), the Normalized Difference Red Edge Index (NDRE) and the Leaf Chlorophyll Index (LCI). Data for each plant (n = 11,104) were obtained for analysis across all dates and sensors. A combined methodology (Spearman’s correlation coefficient, Student’s t-test and decision trees) was used to validate the behaviour of the variables and propose predictive models. The results showed significant differences between the sensors, with a common trend in spatial patterns and a correlation range between 0.45 and 0.68. Integrating both technologies enables multiscale assessment, optimizing agronomic management and supporting more sustainable precision agriculture.
Evaluation of 3D Models of Archaeological Remains of Almenara Castle Using Two UAVs with Different Navigation Systems Juan López-Herrera, Serafín López-Cuervo, Enrique Pérez-Martín, Miguel Ángel Maté-González, Consuelo Vara Izquierdo, José Martínez Peñarroya, Tomás R. Herrero-Tejedor Heritage, 2025 Improvements in the navigation systems incorporated into unmanned aerial vehicles (UAVs) and new sensors are improving the quality of 3D mapping results. In this study, two flights were compared over the archaeological remains of the castle of Almenara, situated in Cuenca, Spain. We performed one with a DJI Phantom 4 (DJI Innovations Co., Ltd., Shenzhen, China) and the other with a Matrice 300 RTK (DJI Innovations Co., Ltd., Shenzhen, China) and the new Zenmuse P1 camera (45 mp, RGB sensor). With the help of the new software incorporated into the Zenmuse P1 camera gimbal, we could significantly reduce the flight time. We analysed the data obtained with these two UAVs and the built-in RGB sensors, comparing the flight time, the point cloud, and its resolution and obtaining a three-dimensional reconstruction of the castle. We describe the work and the flights carried out, depending on the type of UAV and its RTK positioning system. The improvement in the positioning system provides improvements in flight accuracy and data acquisition. We compared the results obtained in similar studies, and thanks to the advances in UAVs and their sensors with better resolution, we managed to reduce the data collection time and obtained 3D models with the same results as those from other types of sensors. The accuracies obtained with the RTK and the P1 camera are very high. The volumes calculated for a future archaeological excavation are precise, and the 3D models obtained by these means are excellent for the preservation of the cultural asset. These models can have various uses, such as the preservation of an asset of cultural interest, or even its dissemination and analysis in various studies. We propose to use this technology for similar studies of archaeological documentation and the three-dimensional reconstruction and visualisation of cultural heritage in virtual visits on the web.
Using Virtual Reality in the Learning of Geomatic Engineering Education Enrique Pérez-Martín, Serafín López-Cuervo Medina, Tomás R. Herrero-Tejedor, Alejandra Ezquerra-Canalejo, Daniel López-Fernández IEEE Computer Graphics and Applications, 2024 Emerging technologies can be effective in enhancing the teaching-learning process. In this paper, virtual reality is used as a tool to support learning and skill acquisition in a subject of geomatics in an engineering degree. The developed tool is an immersive virtual environment that allows access to a first-person observation of the methodology to be followed in the field to carry out the proposed task. In order to validate this tool, a quasi-experiment was performed involving 170 students and several instruments to assess the knowledge acquisition of these students and their perceptions towards the learning experience. The obtained results indicate that the use of virtual reality in the field of geomatics may be a promising means of conveying new knowledge and enhancing learning and competence acquisition in geomatics.
Documentation and Virtualisation of Vernacular Cultural Heritage: The Case of Underground Wine Cellars in Atauta (Soria) Tomás Ramón Herrero-Tejedor, Miguel Ángel Maté-González, Enrique Pérez-Martín, Serafín López-Cuervo, Juan López de Herrera, Luis Javier Sánchez-Aparicio, Paula Villanueva Llauradó Heritage, 2023 The cultural heritage associated with rural systems is extremely valuable and is a sign of identity for cultures that are disappearing or undergoing transformation. This paper explains and illustrates the series of procedures that have been carried out to document and subsequently virtualise the ethnological site of the “El Plantío” underground wine cellars in Atauta. The ensembles of underground wine cellars are located immediately outside the village of Atauta, from which they are separated by the stream of Arroyo de la Laguna or Golbán, thus giving rise to two environments that are characterised by the perfect interrelation between their natural and architectural heritage. The visual and scenic relations between both these elements make this area a prime example of a cultural heritage that is associated with wine production systems. This documentation was obtained through a combination of different geomatic techniques. The results are organised on a web platform to enable their digital visualisation (2D/3D). This platform provides a virtual environment such that users can understand these underground heritage assets in an integrated way together with the immaterial cultural heritage and the cultural landscape—all of which converge on this ethnological site. The project offers different types of audiences, both real and virtual, access to all of the documentation.
Optimization of soil background removal to improve the prediction of wheat traits with UAV imagery Andrés F. Almeida-Ñauñay, Ana M. Tarquis, Juan López-Herrera, Enrique Pérez-Martín, José L. Pancorbo, María D. Raya-Sereno, Miguel Quemada Computers and Electronics in Agriculture, 2023 Grain yield and quality assessment based on remote sensing throughout the growth cycle may contribute to achieve efficient and sustainable wheat production. A trial was conducted to test the suitability of a multispectral sensor onboard an unmanned aerial vehicle (UAV) to estimate yield, protein content, and nitrogen (N) output in winter wheat (Triticum aestivum L.). Furthermore, a method to improve predictions of wheat traits was proposed by sequentially removing soil pixels from the distribution of vegetation index (VI) values. The experimental area, located at Aranjuez (Madrid, Spain), was divided into four sectors with 133 plots in total. Different N doses were applied to the plots to create high experimental intravariability. In each plot, wheat traits were measured at harvest. An (UAV) was flown at growth stages (GS) – GS32, GS39, and GS65 – to ensure correct monitoring of the crop. Four VIs, Normalized Difference Vegetation Index (NDVI), Modified Soil Vegetation Index (MSAVI), Normalized Difference Red Edge Index (NDRE) and Blue-Red Index (BRI1) were selected based on the sensor spectral information and their suitability for estimating wheat traits. A sequential cutting method (threshold value optimization, TVO) was implemented to remove soil background pixels, based on threshold values computed from the VIs distributions. Then, the predictive performance of the VIs in each segmentation was evaluated. Our results indicated that NDVI, MSAVI, and NDRE were able to predict the wheat traits using sensors onboard a UAV. We proposed optimal thresholds ranging from 0.1 to 0.3 depending on the VI and the wheat trait. The TVO method showed an improvement in yield and N output estimation at the stem elongation growth stage (GS32). However, the TVO method achieved a limited improvement in estimating protein content at anthesis (GS65). Overall, our results suggest (a) that soil background reflectance is an essential element of UAV imagery that introduces uncertainty in the estimation of grain yield and quality based on VIs, and (b) that TVO may mitigate the soil effect.
Assessment of tree diameter estimation methods from mobile laser scanning in a historic garden Enrique Pérez-Martín, Serafín López-Cuervo Medina, Tomás Herrero-Tejedor, Miguel Angel Pérez-Souza, Julian Aguirre de Mata, Alejandra Ezquerra-Canalejo Forests, 2021 Geo-referenced 3D models are currently in demand as an initial knowledge base for cultural heritage projects and forest inventories. The mobile laser scanning (MLS) used for geo-referenced 3D models offers ever greater efficiency in the acquisition of 3D data and their subsequent application in the fields of forestry. In this study, we have analysed the performance of an MLS with simultaneous localisation and mapping technology (SLAM) for compiling a tree inventory in a historic garden, and we assessed the accuracy of the estimates of diameter at breast height (DBH, a height of 1.30 m) calculated from three fitting algorithms: RANSAC, Monte Carlo, and Optimal Circle. The reference sample used was 378 trees from the Island Garden, a historic garden and UNESCO World Heritage site in Aranjuez, Spain. The time taken to acquire the data by MLS was 27 min 37 s, in an area of 2.38 ha. The best results were obtained with the Monte Carlo fitting algorithm, which was able to estimate the DBH of 77% of the 378 trees in the study, with a root mean squared error (RMSE) of 5.31 cm and a bias of 1.23 cm. The proposed methodology enabled a supervised detection of the trees and automatically estimated the DBH of most trees in the study, making this a useful tool for the management and conservation of a historic garden.
Environmental assessment of Obstacle Limitation Surfaces (OLS) in airports using geographic information technologies Mª Rosario Contreras-Alonso, Alejandra Ezquerra-Canalejo, Enrique Pérez-Martín, Tomás R. Herrero-Tejedor, Serafín López-Cuervo Medina Plos One, 2020 A series of 3D obstacle limitation surfaces (OLS) define the limits to which objects may project in the airspace in order to configure the airspace around aerodromes that must be kept free from obstacles. The aim is to ensure that aircraft can safely carry out their scheduled operations, and to prevent the aerodromes from becoming unusable due to the proliferation of obstacles in the surrounding area. One such possible obstacle is the vegetation growing in the zone. This work consists of a study of the variation in the vegetation in the El Prat airport (Barcelona-El Prat Josep Tarradellas) and the surrounding area in the years 2011-2018, and of the way in which it has influenced the configuration of the OLS. Until 2010, obstacle studies were carried out every four years but the growth of plant obstacles during this period was not controlled. Although the rate of tree growth depends on several factors such as age, species, site quality and forestry treatment, the parameter analysed in this research is height, as this is what will interfere in the OLS. This study therefore focuses on measuring the height and geolocation of the obstacle in order to determine its influence on the OLS, and on determining the subsequent actions, if any, that need to be taken in regard to this vegetation element to avoid it becoming a risk to operational safety. As a result, the growth and vulnerability of 84 vegetation obstacles from 794 terrain elements have been detected. The result of this study is the design, using geographic information systems, of a tool to assist airport managers in the automated control and monitoring of the vegetation in the obstacle limitation surfaces to avoid compromising the safety of airport operations and mitigating environmental impacts.
Assessment of dsms using backpack-mounted systems and drone techniques to characterise ancient underground cellars in the duero basin (Spain) López-Cuervo Medina, Pérez-Martín, Herrero Tejedor, Prieto, Velasco, Conejo Martín, Ezquerra-Canalejo, Aguirre de Mata Sensors Switzerland, 2019 In this study, a backpack-mounted 3D mobile scanning system and a fixed-wing drone (UAV) have been used to register terrain data on the same space. The study area is part of the ancient underground cellars in the Duero Basin. The aim of this work is to characterise the state of the roofs of these wine cellars by obtaining digital surface models (DSM) using the previously mentioned systems to detect any possible cases of collapse, using four geomatic products obtained with these systems. The results obtained from the process offer sufficient quality to generate valid DSMs in the study area or in a similar area. One limitation of the DSMs generated by backpack MMS is that the outcome depends on the distance of the points to the axis of the track and on the irregularities in the terrain. Specific parameters have been studied, such as the measuring distance from the scanning point in the laser scanner, the angle of incidence with regard to the ground, the surface vegetation, and any irregularities in the terrain. The registration speed and the high definition of the terrain offered by these systems produce a model that can be used to select the correct conservation priorities for this unique space.
Vegetation indices from remote sensing imagery as proxies for yield and grain N in wheat M. Quemada, J.L. Pancorbo, M. Alonso-Ayuso, J.L. Gabriel, J. López-Herrera, E. Pérez-Martín Precision Agriculture 2019 Papers Presented at the 12th European Conference on Precision Agriculture Ecpa 2019, 2019 The use of vegetation indices (VIs) might help to adjust fertilizer and irrigation, increase yield and reduce costs and nitrogen (N) losses. The objectives were to evaluate the use of VIs extracted from remote sensing imagery to estimate crop N status, yield and grain N content in wheat (Triticum aestivum, L.). A field experiment conducted with four N fertilizer levels randomly distributed in 32 plots (25×25 m2), half irrigated and half rain-fed. At two sampling times, biomass and N uptake were determined, ground sensors measurements were taken, and multi-spectral imagery was acquired by an unmanned aerial vehicle. At harvest, yield was recorded with a combine and grain N determined. VIs obtained from ground measurements were highly correlated with those from the aerial platform. Using planar domain VIs, which relate N concentration and biomass, correlated well to crop N status and showed high potential for fertilizer recommendation, as well as yield and grain N prediction in wheat.
