Analysis of vegetation indices to determine nitrogen application and yield prediction in maize (Zea mays L.) from a standard UAV service
(MDPI, 2016)The growing use of commercial unmanned aerial vehicles (UAV) and the need to adjust N fertilization rates in maize (Zea mays L.) currently constitute a key research issue. In this study, different multispectral vegetation ... -
Application of Structure‐from‐Motion photogrammetry to river restoration
(John Wiley & Sons, 2016-11-08)Structure‐from‐Motion (SfM) photogrammetry is now used widely to study a range of earth surface processes and landforms, and is fast becoming a core tool in fluvial geomorphology. SfM photogrammetry allows extraction of ... -
Expedited generation of terrain digital classes in flat areas from UAV images for precision agriculture purposes
(The Animal Consortium, 2017-07-16)Precision agriculture (PA) requires reasonably homogeneous areas for site-specific management. This work explores the applicability of digital terrain classes obtained from a digital elevation model derived from UAV-acquired ... -
Remote Sensing Monitoring of a Coastal-Valley Earthflow in Northwestern Galicia, Spain
(Elsevier, 2019-03-26)Historical air photographs, LiDAR, and an unmanned aerial vehicle (UAV) were used to record the movement, from 1956 to 2018, of a clay and clast earthflow in a coastal valley in northwestern Spain. Two procedures were ...
