Geographic Object-Based Image Analysis (GEOBIA): A new name for a new discipline

Lecture Notes in Geoinformation and Cartography, 2008
What is Geographic Object-Based Image Analysis (GEOBIA)? To answer this we provide a formal definition of GEOBIA, present a brief account of its coining, and propose a key objective for this new discipline. We then, conduct a SWOT1 analysis of its potential, and discuss its main tenets and plausible future. Much still remains to be accomplished.

Explicit area-based accuracy assessment for mangrove tree crown delineation using Geographic Object-Based Image Analysis (GEOBIA)

Earth Resources and Environmental Remote Sensing/GIS Applications VIII, 2017
Effective mangrove management requires spatially explicit information of mangrove tree crown map as a basis for ecosystem diversity study and health assessment. Accuracy assessment is an integral part of any mapping activities to measure the effectiveness of the classification approach.

Environmental Object Recognition in a Natural Image

International Journal of Agricultural and Environmental Information Systems, 2014
Natural images, which are filled with intriguing stimuli of spatial objects, represent our cognition and are rich in spatial information. Accurate extraction of spatial objects is challenging due to the associated spatial and spectral complexities in object recognition.

Applying geographic object-based image analysis (GEOBIA) and data mining to identify secondary forests succession on Santarem Region, Para, Brazil

2017 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2017
The secondary forest has a low diversity of species, however, they have major importance for the reestablishment of ecosystem functions and nutrient stocks lost from the original forests, as well as higher carbon absorption rate of the mature forests.

Methodological framework for ontology-driven geographic object-based image analysis (O-GEOBIA)

2019
Geographic Object-Based Image Analysis (GEOBIA) has emerged as a new sub-discipline of Geographic Information Science. GEOBIA provides methods to delineate real-world geographic objects from Earth Observation (EO) data. GEOBIA methods rely on human expert (domain) knowledge to perform image segmentation, classification, and classification-based ...

Geographic Object-Based Image Analysis (GEOBIA) for inventory mapping of forest-covered landslides: a case study in Jena, Germany

For assessing landslide susceptibility and hazard reliable landslide inventories are essential. Historic landslides might indicate periods of increased landslide activity compared to more recent decades. However, landslide features might have diminished over time especially due to human impact.

Geographic object based image analysis (GEOBIA) for mangrove tree crown delineation using WorldView-2 image data

2015
Providing spatially explicit information of mangrove tree crown is essential to support management and monitoring of mangrove environment. This study developed a method to delineate individual Avicennia marina mangrove tree crown in Whyte Island (Brisbane, Australia) using the newly emerged GEOBIA approach and pan-sharpened WorldView-2 (WV-2, 0.5m ...
