Exploring the Potential of Unmanned Aerial System‐Based Topographic Indices Maps to Evaluate Storm Drain Positioning

Journal of Flood Risk Management, Volume 19, Issue 4, December 2026.
ABSTRACT Urbanisation, climate uncertainty, and limited city budgets have heightened the need for efficient urban drainage management. While advanced hydrodynamic models assess the performance of drainage networks, they are computationally intensive, time‐consuming, and expensive.

Bridging Geomythology and Geospatial Analysis for Flood Risk Assessment in Tamil Nadu

Journal of Flood Risk Management, Volume 19, Issue 4, December 2026.
ABSTRACT The need for more holistic and context‐aware approaches to flood‐risk assessment has become increasingly urgent with extreme climate change events faced globally. Modern models overlook the long‐term environmental knowledge incorporated in ancient literature, myths, and cultural memory as they rely primarily on hydrological and geospatial ...

Collocated Geotechnical and Geophysical Test Dataset at Three Sites in Napier, New Zealand

Earthquake Spectra, Volume 42, Issue 4, November 2026.
Reliable assessment of liquefaction hazard, particularly in the context of groundwater fluctuations associated with hydroclimatic changes and variability between liquefaction assessment methods, necessitates supplementary data and advanced site characterization methods.

Quantifying Deep Ocean Methane Along the Central Chilean Margin

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Cold seeps are dynamic seafloor environments that provide conduits for methane (CH4) to be transferred from marine sediments to the global ocean and, in shallow settings, the atmosphere. These seeps are ubiquitous along continental margins yet their spatial extent and impact on the marine carbon cycle are poorly constrained.

Assessing Habitat Suitability and Exposure of the Endemic Vasconcellea candicans Under Climate Change and Urban Growth in Lima, Peru

Ecology and Evolution, Volume 16, Issue 10, October 2026.
This study integrated ensemble species distribution modelling and urban growth projections to evaluate current and future habitat suitability of V. candicans in the lomas ecosystems surrounding Lima under climate change and urban expansion scenarios. Results identified 2891 km2 of current high‐suitability habitat, with strong scenario‐dependent future ...

Reliability of Direct Georeferencing Phase 1: An Overview of the Current Approaches and Possibilities., Checking and Improving of Digital Terrain Models / Reliability of Direct Georeferencing.

, 2006
After some initial hesitations, the direct georeferencing (DG) of airborne sensors by GPS/INS is now a widely accepted approach in the airborne mapping industry. Implementing DG not only speeds up the mapping process and thus increases the productivity, but also opens the door to new monitoring applications.

Reliability of Direct Georeferencing Phase 2: A Case Study on Practical Problems and Solutions., Checking and Improving of Digital Terrain Models / Reliability of Direct Georeferencing.

, 2006
This report studies a practical problem related to the use of GPS/INS technology for sensor direct georeferencing. It is a case study of a specific, yet typical, situation whre the performance of a GPS/INS was pronounced unsatisfactory for orientation of an airborne sensor.

Georeferencing multi-scale imagery in photogrammetry

, 2007
Georeferencing is crucial to make imagery useful for extracting geospatial information. This thesis presents an economic and feasible approach to georeference multi-scale imagery to the common coordinate system, which is called local coordinate system ...

Improving island occupancy predictions using ecologically informed metrics of area and isolation

Ecology, Volume 107, Issue 10, October 2026.
Abstract Understanding how species occupy islands and habitat patches remains a central question in biogeography, landscape ecology, conservation, and management, especially as natural and anthropogenic processes reconfigure habitat size and connectivity over time.

LacusPyr, a Catalogue of Lakes and Ponds of the Pyrenees

Geoscience Data Journal, Volume 13, Issue 4, October 2026.
The LacusPyr dataset provides a comprehensive, georeferenced inventory of Pyrenean lakes and ponds, integrating key geomorphological attributes that underpin limnological processes. By enabling analyses across spatial, elevation, and watershed scales, this dataset supports research on mountain lake functioning, regional metacommunities, climate ...
