Optimal Parameters for DEM Extraction from IKONOS Data: A Case Study of a Coastal Area
The gap between aerial and satellite photogrammetry is getting smaller as both systems have benefited from great technology improvements in the last years. However, the major advantage of earth observation satellites ...

Biomass estimation of pasture plots with multitemporal UAV-based photogrammetric surveys
Pastures account for more than 56% of the total agricultural area of Ecuador and constitute the main food source for livestock. Hence, the agile, affordable, and reliable quantification of aboveground biomass (AGB) is an ...
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 ...
Detección de cambios en los usos de suelo a partir de clasificaciones no supervisadas para la actualización del SIOSE. Implementación en el territorio gallego
(Universidad Politécnica de Valencia, 2015)
Uno de los elementos básicos a la hora de diseñar políticas de análisis, gestión y planificación del territorio es una buena cartografía de usos de suelo. Para este cometido, se dispone del Corine Land Cover(CLC) a nivel ...
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 ...
