Upzoning the YIMBY rent gap: A transit‐oriented spatial fix

Canadian Geographies / Géographies canadiennes, Volume 70, Issue 3, Autumn / automne 2026.
Abstract This paper takes up the phenomenon of transit‐oriented zoning reform as an urban planning solution to the housing crisis that promises affordability, sustainability, and racial justice. I hypothesize that upzoning near transit creates a vertical rent gap that represents a YIMBY (Yes in My Back Yard) spatial fix, a targeted spatial deregulation

UAV Data Collection Co-Registration: LiDAR and Photogrammetric Surveys for Coastal Monitoring

Drones
When georeferencing is a key point of coastal monitoring, it is crucial to understand how the type of data and object characteristics can affect the result of the registration procedure, and, above all, how to assess the reconstruction accuracy. For this

The Most Elusive Amazonian Mammal? Distribution, Survey, Ecology and Conservation of the Bushy‐Tailed Opossum Glironia venusta

Mammal Review, Volume 56, Issue 2, June 2026.
Integrating multiple data sources, we reveal a broader distribution for Glironia venusta and highlight how sampling strategies shape our understanding of rare arboreal mammals. ABSTRACT Introduction Arboreal and nocturnal mammals in the Amazon remain poorly understood due to low detectability and methodological limitations. Glironia venusta, one of the

Surface grain-size mapping of braided channels from SfM photogrammetry [PDF]

Earth Surface Dynamics
Braided channels are known as fluvial systems with a high heterogeneity of physical conditions, resulting from particularly active interacting processes of coarse sediment sorting and transport.

Spatiotemporal Quantification of Rugulopteryx okamurae in Beach Wrack Using UAV Multispectral Remote Sensing

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 5, May 2026.
ABSTRACT Excessive beach accumulations of stranded macrophytes, also known as wrack, are a growing challenge for coastal ecosystems and management, particularly when dominated by invasive species. The Asian brown alga Rugulopteryx okamurae has rapidly proliferated along the southern coast of Spain, causing significant ecological and socioeconomic ...

Geomorphic Effectiveness of an Extreme Flood in a Mountain River: Evidence From Pre‐ and Post‐Event Surveys in a Subtropical Region of Southern Brazil

Hydrological Processes, Volume 40, Issue 5, May 2026.
The extreme flooding of April 2024 caused a complete “geomorphic reset”, resulting in a 24% widening of the channel and a transition to critical or supercritical flow regimes. The energy of the event broke through the stable armouring layer, reducing the armouring ratio from 7.9 to 4.9 and intensely removing fine sediments from the subsurface.

Accuracy and Limitations of Tools for Analyzing Meander Migration: Consequences of Bend Dynamics and Analysis Interval

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract Channel migration in meandering rivers is commonly quantified by analyzing change over time in positions of river‐channel centerlines extracted from aerial photographs or satellite images. Although several tools have been developed to estimate migration based on centerline changes, the accuracy of these tools has not been rigorously evaluated.

Comparative Assessment of the Effect of Positioning Techniques and Ground Control Point Distribution Models on the Accuracy of UAV-Based Photogrammetric Production

Drones
Unmanned aerial vehicle (UAV) systems have recently become essential for mapping, surveying, and three-dimensional (3D) modeling applications. These systems are capable of providing highly accurate products through integrated advanced technologies ...

Empirical Evaluation and Simulation of GNSS Solutions on UAS-SfM Accuracy for Shoreline Mapping

Drones
Uncrewed aircraft systems (UASs) and structure-from-motion/multi-view stereo (SfM/MVS) photogrammetry are efficient methods for mapping terrain at local geographic scales.
