Determining Suitable Spaceborne SAR Observations and Ground Control Points for Surface Deformation Study in Rugged Terrain With InSAR Technique

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
We aim to address two primary issues using the multitemporal (MT) spaceborne SAR observations and InSAR technique to monitor slope stability in rugged terrains.

Generation of a Digital Terrain Model (DTM) Fusioning WV-2 Images and RTK-derived Topobathymetric Data

open access: yesRevista Brasileira de Cartografia
Digital terrain models (DTMs) are digital elevation models (DEMs) that represent the bare ground surface. They are created by multiple sources, including satellite remote sensing, aerial photography, and ground-based surveys, and are often combined with

Accurate and automatic NOAA-AVHRR image navigation using a global contour matching approach [PDF]

open access: yes, 2000
The problem of precise and automatic AVHRR image navigation is tractable in theory, but has proved to be somewhat difficult in practice. The authors' work has been motivated by the need for a fully automatic and operational navigation system capable of ...

Suitability of ground-based SfM-MVS for monitoring glacial and periglacial processes [PDF]

open access: yes, 2016
Photo-based surface reconstruction is rapidly emerging as an alternative survey technique to lidar (light detection and ranging) in many fields of geoscience fostered by the recent development of computer vision algorithms such as structure from motion ...

A Novel Method for Fast Positioning of Non-Standardized Ground Control Points in Drone Images

open access: yesRemote Sensing, 2021
Positioning the pixels of ground control points (GCPs) in drone images is an issue of great concern in the field of drone photogrammetry. The current mainstream automatic approaches are based on standardized markers, such as circular coded targets and ...

A new asymmetrical corner detector(ACD) for a semi-automatic image co-registration scheme

open access: yes, 2008
Co-registration of multi-sensor and multi-temporal images is essential for remote sensing applications. In the image co-registration process, automatic Ground Control Points (GCPs) selection is a key technical issue and the accuracy of GCPs ...

Camera Calibration for Coastal Monitoring Using Available Snapshot Images

open access: yesRemote Sensing, 2020
Joint intrinsic and extrinsic calibration from a single snapshot is a common requirement in coastal monitoring practice. This work analyzes the influence of different aspects, such as the distribution of Ground Control Points (GCPs) or the image ...

Adverse events in bedaquiline‐ and pretomanid‐based regimens for drug‐resistant tuberculosis from trial, implementation and pharmacovigilance studies

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Abstract The availability of safety data, particularly concerning adverse events (AEs) associated with the new shorter regimen for drug‐resistant tuberculosis (TB) containing a bedaquiline–pretomanid‐based regimen, is still limited. This systematic review aims to provide a comprehensive and updated analysis of AEs related to this new regimen by ...
