Improving forest age estimation to understand subtropical forest regrowth dynamics using deep learning image segmentation of time‐series historical aerial photographs

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Accurately estimating forest age is key to understanding how forests recover and evaluating restoration success. We developed a two‐step deep learning approach using historical greyscale aerial photographs to map forest age at fine spatial scales. By combining a pre‐trained model with localized fine‐tuning, our U‐Net + ResNet50 architecture achieved ...

Unlocking Financial Inclusion: The Dynamics of Bank Account Ownership in Urban Slums

open access: yesSustainable Development, EarlyView.
ABSTRACT Financial inclusion is a key driver of sustainable development, contributing to poverty reduction (SDG 1), gender equality (SDG 5), and reduced inequalities (SDG 10). Despite extensive financial‐inclusion policies in India, residents of urban slums remain largely excluded from formal banking systems.

Mapping School Accessibility in Africa: High‐Resolution Spatial Analysis Uncovers Inequalities in Education Access

open access: yesSustainable Development, EarlyView.
ABSTRACT Education is a cornerstone of sustainable development, yet large disparities in access persist across and within countries—particularly in Africa, where millions remain underserved. Among several factors influencing educational participation, physical accessibility to schools (in terms of travel time) is not comprehensively understood ...

Turkey OpenStreetMap Dataset - Spatial Analysis of Development and Growth Proxies

open access: yesOpen Geosciences, 2019
Number of studies covering major data aspects of OpenStreetMap (OSM) for developed cities and countries are available in scientific literature. However, this is not the case for developing ones mainly because of low data availability in OSM.

Monitoring GPS‐collared moose by ground versus drone approaches: efficiency and disturbance effects

open access: yesWildlife Biology, EarlyView.
Efficient wildlife management requires precise monitoring methods, for example to estimate population density, reproductive success, and survival. Here, we compared the efficiency of drone (equipped with a RGB camera) and ground approaches to detect and observe GPS‐collared female moose Alces alces and their calves. We also quantified how drone (n = 42)

The spatiotemporal influence of socioeconomic factors on the number of OpenStreetMap contributors in China

open access: yesOpen Geosciences
The number of OpenStreetMap (OSM) contributors is closely related to both the quality of OSM data and various socioeconomic factors. This study applies the Geographically and Temporally Weighted Regression (GTWR) model to explore the spatiotemporal ...
