Geographic Object-Based Image Analysis: A Primer and Future Directions
Remote Sensing, 2020 Geographic object-based image analysis (GEOBIA) is a remote sensing image analysis paradigm that defines and examines image-objects: groups of neighboring pixels that represent real-world geographic objects.

GEOBIA systems for massive data processing [PDF]
GEOBIA 2016: Solutions and synergies, 2016 Large portions of the Earth’s landscape are now captured by high-resolution remotely-sensed datasets and turned into corresponding thematic data. Despite these advancements the number of comprehensive, high-resolution land-cover maps is surprisingly low.

Earth and Space Science, Volume 10, Issue 5, May 2023., 2023 Abstract Many studies of Earth surface processes and landscape evolution rely on having accurate and extensive data sets of surficial geologic units and landforms. Automated extraction of geomorphic features using deep learning provides an objective way to consistently map landforms over large spatial extents.

Automated methods for image detection of cultural heritage: Overviews and perspectives
Archaeological Prospection, Volume 30, Issue 2, Page 153-169, April/June 2023., 2023 Abstract Remote sensing data covering large geographical areas can be easily accessed and are being acquired with greater frequency. The massive volume of data requires an automated image analysis system. By taking advantage of the increasing availability of data using computer vision, we can design specific systems to automate data analysis and ...
