Drought Impact on Industrial Water Discharges in Spain's Agri‐Food Sector

Hydrological Processes, Volume 40, Issue 7, July 2026.
The PRTR–SPEI panel estimates confirm a positive and statistically stable effect of droughts on industrial discharges, with consistent increases in COD and nitrogen under more negative SPEI scores. This result reflects a structural relationship between hydrological stress and industrial behaviour: reduced flows and dilution capacity during dry periods ...

Habitat‐based spatial patterns enable realistic reconstruction of plant spatial arrangements across complex landscapes

Oikos, Volume 2026, Issue 7, July 2026.
Spatially explicit individual‐based models provide a powerful way to explore spatial dynamics when direct observation is not feasible. But for many ecological applications, these models require detailed data on the initial spatial arrangement and traits of individuals – information rarely available in large, heterogeneous or novel landscapes.

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

Permafrost and Periglacial Processes, Volume 37, Issue 3, Page 391-415, July/September 2026.
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

Decision Of EO Parameters Based On Direct Georeferencing Using SmartBase

Journal of the Korean Society of Surveying, Geodesy, Photogrammetry and Cartography, 2013
Recently, it is a pretty well known way to compute GPS/INS using Continuously Operating Reference Station (CORS) and Network-based RTK for obtaining Exterior Orientation (EO) parameters of aerial photogrammetry. In this study, it is way to compute Exterior Orientation (EO) parameters using ground base stations, using Continuously Operating Reference ...

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

Permafrost and Periglacial Processes, Volume 37, Issue 3, Page 473-497, July/September 2026.
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.

Transformation of UAV Attitude and Position for Use in Direct Georeferencing

The direct georeferencing in aerial photogrammetry requires precise measurement of position and attitude of an image sensor, because the object point position is computed directly using this data.

Direct georeferencing with correction of map projection distortions for active imaging

Geoinformatics FCE CTU, 2016
In aerial photogrammetry, the Cartesian coordinate system for the description of object space is commonly used. In contrast, many projects have to be processed in the space combined by the composition of a map projection and Vertical datum. In that space, some geometric deformations exist.

Flowering out of sync: Climate change alters the reproductive phenology of Terminalia paniculata in the Western Ghats of India

PLANTS, PEOPLE, PLANET, Volume 8, Issue 4, Page 1322-1333, July 2026.
Understanding how climate change impacts the plant life cycle is critical for maintaining biodiversity and ecosystem services. Our findings suggest that Terminalia paniculata Roth, a common tropical deciduous tree species in the Western Ghats, is now flowering and fruiting at more scattered times than it used to in the past.

Herbarium digitisation sheds light on historical distribution and drivers of population extinction of a peat bog specialist

PLANTS, PEOPLE, PLANET, Volume 8, Issue 4, Page 1334-1344, July 2026.
Biodiversity loss threatens ecosystem services and human well‐being. Understanding the extent and causes of changes in biodiversity over time can help protect species and their habitats. Herbaria house carefully documented and curated specimens collected by generations of botanists.
