DIGITAL ELEVATION MODEL CORRECTION IN URBAN AREAS USING EXTREME GRADIENT BOOSTING, LAND COVER AND TERRAIN PARAMETERS [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences
The accuracy of digital elevation models (DEMs) in urban areas is influenced by numerous factors including land cover and terrain irregularities. Moreover, building artefacts in global DEMs cause artificial blocking of surface flow pathways.

Exploring the Role of Competitiveness in Sustainability Standards: Insights From an Animal Welfare Scheme Adopted by Supermarkets

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Research on supermarket‐related voluntary sustainability standards (VSSs) is divided on whether competition helps or hinders efforts to reduce negative social and environmental impacts. This paper examines how the standardization process shapes these outcomes.

Human pressure, habitat heterogeneity and species traits jointly determine the level of dark diversity in coastal fish communities

Ecography, EarlyView.
Understanding how anthropogenic pressures and environmental gradients shape coastal fish communities is a central question in biogeography and marine conservation. Yet, the set of species expected to occur at a site given ecological conditions but being absent – the so‐called dark diversity – has received far less attention than observed species, even ...

Assessment of the global Copernicus, NASADEM, ASTER and AW3D digital elevation models in Central and Southern Africa

Geo-spatial Information Science
Validation studies of global Digital Elevation Models (DEMs) in the existing literature are limited by the diversity and spread of landscapes, terrain types considered and sparseness of groundtruth.

The EU Deforestation Regulation: Challenges, Opportunities and the Potential Impacts on the Producing Countries of Cocoa and Coffee

Environmental Policy and Governance, EarlyView.
ABSTRACT The European Union Deforestation Regulation (EUDR) is a policy that prohibits access to the EU market for commodities that are linked to deforestation. We did a systematic review to understand perceived challenges, opportunities and potential impacts of the EUDR on producing countries of cocoa and coffee.

A Geographic Information System (GIS)–CRiteria Importance Through Intercriteria Correlation (CRITIC) Framework for Selecting Solar Photovoltaics Sites: A Case Study

Energy Science &Engineering, EarlyView.
A novel framework integrating environmental constraints, topography, infrastructure accessibility, and solar irradiation was developed to identify optimal utility‐scale solar photovoltaics (PV) sites in Lithuania. Western and central Lithuania showed the highest suitability for future solar PV expansion.

Ranking of 10 Global One-Arc-Second DEMs Reveals Limitations in Terrain Morphology Representation

Remote Sensing
At least 10 global digital elevation models (DEMs) at one-arc-second resolution now cover Earth. Comparing derived grids, like slope or curvature, preserves surface spatial relationships, and can be more important than just elevation values.
