SUPERVISED DETECTION OF BOMB CRATERS IN HISTORICAL AERIAL IMAGES USING CONVOLUTIONAL NEURAL NETWORKS [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2019
The aftermath of the air strikes during World War II is still present today. Numerous bombs dropped by planes did not explode, still exist in the ground and pose a considerable explosion hazard.

Bed‐level tools for monitoring erosion and accretion patterns: Flume validation and field testing

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Monitoring short‐term changes in surface sediment elevation is fundamental to understanding erosion, transport, and deposition dynamics in shallow coastal environments. However, commonly used field approaches, such as horizontal markers, sediment erosion tables, subsurface sediment plates, or erosion pins, are not always cross‐validated under ...

Unveiling Saint Theobald: A Multidisciplinary Bioanthropological Investigation

open access: yesInternational Journal of Osteoarchaeology, EarlyView.
ABSTRACT Saint Theobald of Provins (1033–1066), a French nobleman who embraced voluntary poverty, hermitism, and pilgrimage, represents an early figure in the medieval ascetic movement. He holds historical significance for the diffusion of 11th‐century ascetic ideals, as a hermit saint associated with the Camaldolese order and venerated across northern

Permafrost Distribution in the Canadian Rockies: Key Variables Influencing Patch‐Scale Variability

open access: yesPermafrost and Periglacial Processes, EarlyView.
ABSTRACT The spatial distribution of permafrost in mountainous regions is influenced by various factors such as topography, climate, vegetation, and substrate. Despite the existence of comprehensive permafrost maps at national and global levels, they fail to accurately represent the patch‐scale (e.g., < 25 m) permafrost distribution in characteristic ...

4D-SFM photogrammetry for monitoring sediment dynamics in a debris-flow catchment: Software testing and results comparison [PDF]

open access: yes, 2018
In recent years, the combination of Structure-from-Motion (SfM) algorithms and UAV-based aerial images has revolutionised 3D topographic surveys for natural environment monitoring, offering low-cost, fast and high quality data acquisition and processing.

The Age and Origin of Block Deposits in the Victorian Alps, Australia

open access: yesPermafrost and Periglacial Processes, EarlyView.
ABSTRACT Large periglacial block deposits are found in the mountains of southeastern Australia. Despite their widespread distribution, their mode of formation and age are poorly understood. These landforms hold considerable potential to shed light on the nature of cooling during glacial periods. In this paper we present a new study of block deposits in

Capturing the Multi‐Decadal Evolution of Glacier–Permafrost Interactions in a High‐Alpine Environment (Ritord, Western Swiss Alps)

open access: yesPermafrost and Periglacial Processes, EarlyView.
ABSTRACT This study investigates the multi‐decadal evolution of a glacier forefield under permafrost conditions in the Combins Massif (western Swiss Alps). A multi‐method approach based on historical and recent datasets is used to analyze its landform components.

New developments in medical photogrammetry

open access: yes, 2009
Conventional photogrammetric techniques have been used for a broad variety of medical applications. Amongst them, craniofacial mapping, human trunk and extremity mapping, wound and sore mapping, as well as dental mapping are the most common.

The hands-on learning of practical photogrammetry for archaeology

open access: yes, 2023
Photogrammetric techniques have been applied in archaeology for over 140 years, but recently, automation in software has significantly increased the popularity of photogrammetry. In 2018, the Master’s Programme in Cultural Heritage at Helsinki University
