Geographic Object-Based Image Analysis Framework for Mapping Vegetation Physiognomic Types at Fine Scales in Neotropical Savannas

Remote Sensing, 2020
Regional maps of vegetation structure are necessary for delineating species habitats and for supporting conservation and ecological analyses. A systematic approach that can discriminate a wide range of meaningful and detailed vegetation classes is still ...

Using Texture‐Based Image Segmentation and Machine Learning With High‐Resolution Satellite Imagery to Assess Permafrost Degradation Landforms in the Russian High Arctic

Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 3, September 2025.
Abstract Amplified climate change across the Arctic causes significant permafrost thaw and an increase of permafrost degradation landforms. These landforms range from fine‐scale degrading ice wedge‐polygon‐networks to large‐scale features such as thermo‐erosional gullies and reshape entire landscapes.

An Integrated Framework for the Assessment of Meso‐Scale Physical Habitats in Gravel‐Bed Rivers Using Remote Sensing and 2D Hydraulic Modeling

WIREs Water, Volume 12, Issue 3, May/June 2025.
A five‐step integrated modeling framework combines remote sensing and two‐dimensional hydraulic modeling to describe mesohabitats and assess suitability for target species. Remote sensing provides a Digital Terrain Model and an orthophoto (step 1) that can be used to classify and map environmental descriptors such as substrate and refugia (step 2).

Caatinga Typologies: A Review to Support Mapping Through Orbital Remote Sensing and GEOBIA

, 2018
A Caatinga é um bioma exclusivamente brasileiro, sendo um dos menos conhecidos e estudados no país. A oscilação da disponibilidade hídrica no semiárido brasileiro, faz com que sua vegetação seja extremamente dinâmica e sazonal.

Evaluating the Performance of Geographic Object-Based Image Analysis in Mapping Archaeological Landscapes Previously Occupied by Farming Communities: A Case of Shashi–Limpopo Confluence Area

Remote Sensing, 2023
The use of pixel-based remote sensing techniques in archaeology is usually limited by spectral confusion between archaeological material and the surrounding environment because they rely on the spectral contrast between features.

Assessing natural and human‐induced river corridor changes using object‐based image analysis (Orljava River, Croatia)

River Research and Applications, Volume 41, Issue 2, Page 285-300, February 2025.
Abstract This study employs object‐based image analysis to investigate land cover dynamics and channel changes in the managed corridor of the Orljava River following anthropogenic vegetation removal and a flood event. By classifying RGB and near‐infrared (NIR) images from the decade 2011–2021, five land cover classes within the river corridor were ...

Geographic object‐based image analysis (GEOBIA) of the distribution and characteristics of aeolian sand dunes in Arctic Sweden

, 2023
Current climate change in the Arctic is unprecedented in the instrumental record, with profound consequences for the environment and landscape. In Arctic Sweden, aeolian sand dunes have been impacted by climatic changes since their initial formation ...
