IR Thermography from UAVs to Monitor Thermal Anomalies in the Envelopes of Traditional Wine Cellars: Field Test
Infrared thermography (IRT) techniques for building inspection are currently becoming increasingly popular as non-destructive methods that provide valuable information about surface temperature (ST) and ST contrast ...
A PBeL for training non-experts in mobile-based photogrammetry and accurate 3-D recording of small-size/non-complex objects
The high level of automation, user-friendliness and cost-effectiveness of photogrammetry have contributed significantly to its popularisation among amateur users in recent years. Paradoxically, this situation poses challenges ...
Plant survival monitoring with UAVs and multispectral data in difficult access afforested areas
(Taylor & Francis, 2018-10-02)
Water supply devices enable afforestation in dry climates and on poor lands with generally high success rates. Previous survival analyses have been based on the direct observation of each individual plant in the field, ...
Above-ground biomass estimation of arable crops using UAV-based SfM photogrammetry
(Taylor & Francis, 2018-12-03)
Methods of estimating the total amount of above-ground biomass (AGB) in crop fields are generally based on labourious, random, and destructive in situ sampling. This study proposes a methodology for estimating herbaceous ...
DEM shading method for the correction of pseudoscopic effect on multi-platform satellite imagery
(Taylor & Francis Group, 2014-12-13)
The pseudoscopic effect in satellite imagery causes perception problems for rugged terrain. The topographic relief is perceived in reverse in images with southeast illumination because of the position of land shadows ...
Virtual Globes for UAV-based data integration: Sputnik GIS and Google Earth™ applications
(Taylor & Francis, 2018-03-01)
The integration of local measurements and monitoring via global-scale Earth observations has become a new challenge in digital Earth science. The increasing accessibility and ease of use of virtual globes (VGs) represent ...
A World Wide Web-Based Practice That Disseminates Photogrammetry. Inspiring secondary students to pursue geomatics careers
The D3MOBILE Metrology World League was established in 2013 with the aim of encouraging curiosity and interest in science, and particularly geoscience, in the secondary students of grades ISCED 1 and 2. Presented as an ...
A hybrid photogrammetry approach for archaeological sites: Block alignment issues in a case study (the Roman camp of A Cidadela)
Photogrammetry is a cost-effective and versatile technique used for the threedimensional (3D) registration of archaeological heritage sites. Managing datasets of heterogeneous images in terms of camera type, elevation ...
Evaluation of a low-cost approach to 2-D digital image correlation vs. a commercial stereo-DIC system in Brazilian testing of soil specimens
Due to their cost, high-end commercial 3D-DIC (digital image correlation) systems are still inaccessible for many laboratories or small factories interested in lab testing materials. These professional systems can provide ...
