Automated corrosion surface quantification in steel transmission towers using UAV photogrammetry and deep convolutional neural networks

open access: yesComputer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 14, Page 2050-2070, 3 June 2025.
Abstract Corrosion in steel transmission towers poses a challenge to structural integrity and safety, requiring efficient detection methods. Traditional visual inspections are unsustainable due to the complexity and volume of structures. Their manual, qualitative, and subjective nature often leads to inconsistencies in maintenance planning.

Advancing social‐ecological restoration through elicitation of cultural ecosystem services and landscape feature perceptions in restored quarries: a Flickr data analysis

open access: yesRestoration Ecology, Volume 33, Issue 4, May 2025.
With increasing urbanization and demand for construction materials, quarries have become central to the recovery of degraded landscapes into spaces that offer ecological, but also social benefits. While ecological restoration has long been investigated, integrated social‐ecological restoration of post‐quarrying landscapes remains underexplored.

Challenges in geotagging encyclopaedias

open access: yesStudia Lexicographica, 2021
Encyclopaedias, as a reliable source of knowledge produced by experts and lexicographers, are, among other characteristics, known for their reliability, accuracy, and precision. The spatial representation of encyclopedic knowledge has in a way been used for a long time, such as in thematic maps, but the digital age has brought significantly expanded ...

Autonomous post‐disaster indoor navigation and survivor detection using low‐cost micro aerial vehicles

open access: yesComputer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 1, Page 130-144, 2 January 2025.
Abstract This paper introduces an innovative autonomous survivor detection pipeline tailored for low‐cost micro aerial vehicles (MAVs) operating in post‐disaster indoor environments. This consists of three main components: (1) a novel pipeline for survivor geotagging, which includes autonomous navigation, mapping, and detection of survivors using ...

Crowdsourced Data Reveal Shortcomings in Precipitation Phase Products for Rain and Snow Partitioning

open access: yesGeophysical Research Letters, Volume 51, Issue 24, 28 December 2024.
Abstract Reanalysis products support our understanding of how the precipitation phase influences hydrology across scales. However, a lack of validation data hinders the evaluation of a reanalysis‐estimated precipitation phase. In this study, we used a novel dataset from the Mountain Rain or Snow (MRoS) citizen science project to compare 39,680 MRoS ...

Can Geotags Help Image Recognition? [PDF]

open access: yes, 2009
In this paper, we propose to exploit geotags as additional information for visual recognition of consumer photos to improve its performance. Geotags, which represent places where the photos were taken, for photos can be obtained automatically by carrying a portable small GPS device with digital cameras.

Online tourist image on Instagram. Study case: Obcina Mare, Suceava

open access: yesČasopis Socìalʹno-Ekonomìčnoï Geografìï. Часопис соціально-економічної географії
During the past decades tourism has evolved, and along with it also the technology. So, it makes only sense to be studied together. The present study focuses on the online Instagram image of Obcina Mare, an area located in northern Romania, known for its

Finding Wormholes with Flickr Geotags

open access: yes, 2010
We propose a kernel convolution method to predict similar locations (wormholes) based on human travel behaviour. A scaling parameter can be used to define a set of relevant users to the target location and we show how the geotags of these users can effectively be aggregated to predict a ranking of similar locations.

State of the Geotags: Motivations and Recent Changes

open access: yesProceedings of the International AAAI Conference on Web and Social Media, 2017
The widespread adoption of smartphones has made it possible for large numbers of people to geotag their social media posts. Past work has studied the reasons people tag their location and the ways they do so on location-based social networks like Foursquare.
