Spatiotemporal Changes in 3D Building Density with LiDAR and GEOBIA: A City-Level Analysis [PDF]
Remote Sensing, 2020 Understanding how, where, and when a city is expanding can inform better ways to make our cities more resilient, sustainable, and equitable. This paper explores urban volumetry using the Building 3D Density Index (B3DI) in 2001, 2010, 2019, and quantifies changes in the volume of buildings and urban expansion in Luxembourg City over the last two ...

Permafrost and Periglacial Processes, Volume 34, Issue 1, Page 22-36, January/March 2023., 2023 Abstract 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 after the retreat of the last glacial ice sheet.

COMPARATIVE ASSESSMENT BETWEEN PER-PIXEL AND OBJECT-ORIENTED FOR MAPPING LAND COVER AND USE [PDF]
Engenharia Agrícola, 2017 : The traditional per-pixel classification methods consider only spectral information, and may be limited. Object-based classifiers, however, also consider shape and texture, firstly segmenting the image, and then classifying individual objects.

Application of Geobia to map the seafloor [PDF]
GEOBIA 2016: Solutions and synergies, 2016 Geographic Object-Based Image Analysis (GEOBIA) has been successfully employed to map terrestrial environments. However, 71% of Earth's surface is covered by seawater and standard optical methods suitable for mapping the land surface have limited application in such environments.

Detecting Atlantic forest patches applying GEOBIA and data mining techniques [PDF]
GEOBIA 2016: Solutions and synergies, 2016 Brazilian Atlantic Forest is one of the most devastated tropical forests in the world. Considering that approximately only 12% of its original extent still exists, studies in this area are highly relevant. In this context, this study maps the land cover of Atlantic Forest within the Protected Area of ‘Macae de Cima’, in Rio de Janeiro State, Brazil ...
