Accuracy assessment of RTK/PPK UAV-photogrammetry projects using differential corrections from multiple GNSS fixed base stations

Geocarto International, 2023
Unmanned aerial vehicles (UAVs) equipped with global navigation satellite system-real-time kinematic (GNSS RTK) receivers allow direct georeferencing of the photogrammetric project without using ground control points (GCPs).

A weighted least squares solution for space intersection of spaceborne stereo SAR data [PDF]

, 2001
The use of stereoscopic SAR images offers an alternative to interferometric SAR for the generation of digital elevation models (DEMs). The stereo radargrammetric method is robust and can generate DEMs of sufficient accuracy to geocode SAR images ...

Effective Altruism and Care Ethics

Journal of Applied Philosophy, EarlyView.
ABSTRACT Effective altruism (EA) has received some of its most vocal criticisms from supporters of care ethics. In this article I take a comparative approach to determine whether a compelling critique of EA can emerge from care ethics at the ethical level, and more generally how much common ground can be found between the two.

Accuracy Assessment of a UAV Direct Georeferencing Method and Impact of the Configuration of Ground Control Points

Drones, 2022
Unmanned aerial vehicles (UAVs) can obtain high-resolution topography data flexibly and efficiently at low cost. However, the georeferencing process involves the use of ground control points (GCPs), which limits time and cost effectiveness.

Use of a Bacteriophage Lysin to Control Axillary Malodor

JEADV Clinical Practice, EarlyView.
ABSTRACT Background Axillary malodor is primarily caused by bacteria, particularly Staphylococcus hominis, which metabolize apocrine secretions into volatile compounds. Traditional deodorants contain antiseptics that can disrupt the skin microbiome and cause irritation. Alternative methods of odor control are being sought but so far without success. We

Multicenter Study Results on Expanded Indications in Med‐EL Pediatric Cochlear Implant Population

The Laryngoscope, EarlyView.
ABSTRACT Objectives To demonstrate safety and efficacy of MED‐EL cochlear implants (CIs) in children aged < 12 months and in children aged 12–71 months with residual hearing. Methods This was a multicenter, nonrandomized, single‐subject, repeated‐measures study with prospective (N = 38; 26 < 12 months of age) and retrospective (N = 209; 70 < 12 months ...

A landslide monitoring method using data from unmanned aerial vehicle and terrestrial laser scanning with insufficient and inaccurate ground control points

Journal of Rock Mechanics and Geotechnical Engineering
Non-contact remote sensing techniques, such as terrestrial laser scanning (TLS) and unmanned aerial vehicle (UAV) photogrammetry, have been globally applied for landslide monitoring in high and steep mountainous areas.

Accuracy Analysis of a Dam Model from Drone Surveys

Sensors, 2017
This paper investigates the accuracy of models obtained by drone surveys. To this end, this work analyzes how the placement of ground control points (GCPs) used to georeference the dense point cloud of a dam affects the resulting three-dimensional (3D ...
