A processing methodology with GNSS observations to obtain Zenith Tropospheric Delay using Bernese GNSS Software version 5.2 is revised in order to obtain Precipitable Water Vapor (PWV). The most traditional PWV observation method is the radiosonde an...

Identification and classification of the different structures and infrastructures that make up a city (conventional buildings, power stations, nuclear power stations, routes of communication, etc.) are of great importance at the time of characterize...

The study looks forward to define a methodology that can improve the quality of the wine produced, through selective crop management, for which a multiple regression analysis was used between satellite images Sentinel 2 and polyphenols and color inde...

This research analyses the glacier recession in the surface area of the Vodudahue river basin glaciers located in Chile, at Comau fjord. A multi-temporal analysis was performed by utilizing Landsat imagery from 1987 to 2017 at a 10-year interval. Als...

In this paper we briefly analyse the integration into web access of data recorded from the archaeological area of Khatm al Melaha (Emirate of Sharjah, United Arab Emirates), combining different geomatic techniques at different scales from a broad yet...

This paper tackles the problem of object recognition in high-resolution aerial imagery and addresses the application of Deep Learning techniques to solve a challenge related to detecting the existence of geospatial elements (road network) in the avai...

This paper shows the progress in the development of two computer vision applications for measuring skin wounds. Both applications have been written in Python programming language and make use of OpenCV and Scipy open source libraries. Their objective...

Biometeorology is the field that relates meteorological and climatic variables with humans, animals and the environment in order to be studied jointly with their geographical distribution. The wide variety of data sources and the highly specialised d...

GEOBIA is an alternative to create and update land cover maps. In this work we assessed the combination of geographic datasets of the Cajas National Park (Ecuador) to detect which is the appropriate dataset-algorithm combination for the classificatio...

The objective of this work is to build a Volunteered Geographic Information System (VGIS) using a methodological design process. The VGIS design focuses on coordinating its three main components—project (organization), participants (community), and t...

Three-dimensional (3D) models are a useful tool for cranial deformation analysis in infants. The registration of the head 3D models to a known coordinate system is vital for the obtainment of parameters and indexes that quantify deformation. In this...

The research project “Development of a Mobile Mapping System for multi-purpose applications composed of a low-cost inertial measuring unit, a GNSS receiver and a close-range LIDAR” consists on considerations about the design of an aerial...

The objective of this work is to monitor the mining subsidence in a mountain range sector of central Chile between 2014 and 2018 through the processing of a time series of Sentinel 1 images using differential interferometry techniques (DInSAR). As a...

GNSS reflectometry (GNSS-R) a technique for the study of variations in the height of sea level and inland waters, and for the study of soil moisture, based on the comparison of the direct and reflected noise signal. The main advantage of this method...

Fine particulate matter (PM_2.5) is a global problem that affects the population health and contributes to climate change. Remote sensing provides useful information for the development of air quality models. This work aims to obtain a daily model of...

Image-based characterisation offers accurate results for colour recording in cultural heritage documentation tasks. Although numerous researches are focused on improving either the mathematical model used or the workflow technical details, in this pa...

We present a procedure for exposure and vulnerability evaluation that integrates LiDAR, orthophotos, and other ancillary datasets. It comprises three phases: (1) city stratification into homogeneous regions; (2) exposure database compilation; and (3)...

The H2020 MOMIT project (Multi-scale Observation and Monitoring of railway Infrastructure Threats, http://www.momit-project.eu/) is focused on showing how remote sensing data and techniques may help to monitor railway infrastructures. One of the haza...

The present work is part of the resilience study of urban areas, where the study area is the urban center of Valdivia (Chile). The aim is to catalog and identify buildings and urban blocks for the subsequent evaluation of exposure and vulnerability t...

National Geographic Institute of Spain has a strong background concerning technical aspects of geodetic VLBI. As a step forward in this field, a VLBI analysis team has been set up and tests with different software packages have been carried out. In t...

Remote sensing and advanced statistical models have been used to assess actual biomass and to analyze the biomass growth in a mature forest of Pinus halepensis Mill. Biomass maps using Landsat-5 in 2011 and Landsat-8 imagery in 2017 and non-parametri...

The upper section of the Mapocho river basin is in constant danger of landslides. This study had the objective of zoning the upper Mapocho river basin for the susceptibility of landslides using hydrological, geological, and geomorphological data. Are...

This paper presents the advances in the design and implementation of a geodesign framework and workflow for the development of HVEI projects, which is supported by corporate methodologies and by the execution of automatic models guaranteeing the trac...

Airborne full-waveform LiDAR (ALS_FW) is able to register forest structure properties, essential for fire prevention, in more detail than airborne discrete LiDAR (ALS_D). However, few studies have analyzed ALS_FW methodological parameters (i.e., voxel s...
