Text and Topos: British Travellers to Real‐and‐Imagined Classical Sites, c. 1560–1820

open access: yesHistory, Volume 110, Issue 393, Page 588-605, December 2025.
Abstract Early‐modern British travellers to the Mediterranean often understood their journeys through the lens of classical texts and culture. Historians sometimes explain this as an imaginative phenomenon: travellers’ preconceptions shaped by classical knowledge guided their subsequent comprehension and activity.

Evaluating of applying image fusion and optimizing techniques for improving the scale parameter of segmentation in object-based image analysis approach [PDF]

open access: yesنشریه جغرافیا و برنامه‌ریزی, 2018
Segmentation is one of the basic method of the information extraction within the object-based image analysis (OBIA) approach. This process separates initial and main objects which are basis for OBIA.

Predicting growing stock volume of Eucalyptus plantations using 3-D point clouds derived from UAV imagery and ALS data [PDF]

open access: yes, 2019
Estimating forest inventory variables is important in monitoring forest resources and mitigating climate change. In this respect, forest managers require flexible, non-destructive methods for estimating volume and biomass.

Linking Land Use, Seasonal Variation and Water Quality Through Dissolved Organic Matter Optical Properties in the Doce River Basin

open access: yesEcohydrology, Volume 18, Issue 7, October‐November 2025.
ABSTRACT Human activities such as agriculture, mining and urbanization have profoundly altered tropical river systems, yet conventional water quality indicators often fail to fully capture these impacts, especially in turbid waters. In the Doce River Basin, Southeast Brazil, the characterization of dissolved organic matter (DOM) through its optical ...

Improving parameters selection of a seeded region growing method for multiband image segmentation [PDF]

open access: yes, 2015
In the last decade, Object Based Image Analysis (OBIA) has been accepted as an effective method for processing high spatial resolution multiband images. This image analysis method is an approach that starts with the segmentation of the image.

Improve Carbon Budget Assessment in Floodplain Wetlands Using Hydrodynamic and Integrated Machine Learning Models

open access: yesWater Resources Research, Volume 61, Issue 10, October 2025.
Abstract Floodplain wetlands play a crucial role in the global carbon cycle, yet the spatiotemporal variation of carbon flux in floodplain wetlands remains poorly understood due to complex hydrological processes. Here, we present an integrated framework to upscale net ecosystem CO2 exchange (NEE) in floodplain wetlands by combining eddy covariance ...

Studying collective animal behaviour with drones and computer vision

open access: yesMethods in Ecology and Evolution, Volume 16, Issue 10, Page 2229-2259, October 2025.
Abstract Drones are increasingly popular for collecting behaviour data of group‐living animals, offering inexpensive and minimally disruptive observation methods. Imagery collected by drones can be rapidly analysed using computer vision techniques to extract information, including behaviour classification, habitat analysis and identification of ...

Automated delineation and morphometry of unclassified subglacial bedforms

open access: yesBoreas, Volume 54, Issue 4, Page 506-526, October 2025.
We present an automated tool for mapping and analysing subglacial bedforms using volumetric obscurance, without classification. Tested on ArcticDEM data, the method produces bedform outlines with 75% correspondence compared to manually digitized maps.
