Pansharpening largely preserves the normalized difference vegetation index: a multi-sensor comparison with PRISMA, Landsat 9, and field spectroscopy

Frontiers in Remote Sensing
Pansharpening is widely used to increase the spatial resolution of satellite imagery, yet its effects on vegetation indices derived from hyperspectral sensors remain poorly quantified.

Landsat 9 Transfer to Orbit of Pre-Launch Absolute Calibration of Operational Land Imager (OLI)

Remote Sensing
Landsat 9 Operational Land Imager (L9-OLI) was launched on 27 September 2021, after completing a successful radiometric pre-launch calibration and characterization phase. The radiometric math model that governs the ground system—the data processing and analysis system (DPAS)—uses various calibration parameters that had been derived based on the pre ...

A Decadal Home‐Range Dynamics and Habitat Shift in Golden Snub‐Nosed Monkey (Rhinopithecus roxellana)

Integrative Zoology, EarlyView.
This study provides novel insights into the biogeographic patterns of the Sichuan golden snub‐nosed monkey, particularly in terms of habitat suitability and spatial‐use strategies. We found that habitat suitability has expanded over the past decade, with substantial shifts in the environmental factors influencing habitat suitability, from terrain and ...

Water Quality Monitoring Using Landsat 8 OLI in Pleasant Bay, Massachusetts, USA

Remote Sensing
Water quality monitoring is essential to assess and manage anthropogenic eutrophication, especially for coastal estuaries in heavily populated areas. Current monitoring techniques rely on in situ sampling, which can be expensive and limited in spatial ...

Aligning Transnational due Diligence: The EU Deforestation Regulation and Brazil's Fragmented Beef Governance

Global Policy, EarlyView.
ABSTRACT Transnational due diligence regulations, such as the European Union Regulation on Deforestation‐Free Products (EUDR), are reshaping sustainability governance by transforming voluntary norms into binding global rules. Yet, their effectiveness depends on how well they align with domestic governance systems and on the power asymmetries that ...

Bureaucrat assignments as instruments of political control: Theory and evidence from land administration officials in India

American Journal of Political Science, EarlyView.
Abstract This paper investigates how politicians use the assignment of officials to geographical posts—a personnel system found in many countries—as a system of incentives to control, and possibly corrupt, bureaucratic behavior. The argument is developed with a matching model and tested with a nationwide survey of Indian officials who administer land ...

PRISMA vs. Landsat 9 in lithological mapping − a K-fold Cross-Validation implementation with Random Forest

Egyptian Journal of Remote Sensing and Space Sciences
The selection of an optimal dataset is crucial for successful remote sensing analysis. The PRISMA hyperspectral sensor (with 240 spectral bands) and Landsat OLI-2 (boasting high dynamic resolution) offer robust data for various remote sensing ...

Habitat loss and fragmentation for an old‐forest species is driven by severe wildfire and drought

Conservation Science and Practice, EarlyView.
We examined the long‐term trends in habitat for California spotted owls and attributed habitat changes to specific drivers. We found that the 43% decline in habitat from 1985 to 2022 could primarily be attributed to wildfire and drought. Habitat patches also became smaller and more isolated over time.
