GEOBIA Achievements and Spatial Opportunities in the Era of Big Earth Observation Data [PDF]

ISPRS International Journal of Geo-Information, 2019
The primary goal of collecting Earth observation (EO) imagery is to map, analyze, and contribute to an understanding of the status and dynamics of geographic phenomena. In geographic information science (GIScience), the term object-based image analysis (OBIA) was tentatively introduced in 2006.

A Fuzzy Spatial Reasoner for Multi-Scale GEOBIA Ontologies

Photogrammetric Engineering & Remote Sensing, 2015
Abstract In Geographic Object-Based Image Analysis (GEOBIA) an image is partitioned into objects by a segmentation algorithm. These objects are then classified into semantic categories based on unsupervised/ supervised methods, or knowledge-based methods, such as an ontology.

Integrating GEOBIA, Machine Learning, and Volunteered Geographic Information to Map Vegetation over Rooftops [PDF]

ISPRS International Journal of Geo-Information, 2018
The objective of this study is to evaluate operational methods for creating a particular type of urban vegetation map—one focused on vegetation over rooftops (VOR), specifically trees that extend over urban residential buildings. A key constraint was the use of passive remote sensing data only.

Integration of SAR and GEOBIA for the Analysis of Time-Series Data

IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018
In this work, we present a new architecture for the analysis multitemporal SAR data combining classic synthetic aperture radar processing and geographical object-based image analysis. The architecture exploits the characteristics of the recently introduced RGB products of the Level- $1\alpha$ and Level- $1\beta$ families, employing self-organizing ...

Using GEOBIA for feature extraction from multitemporal SAR images: Preliminary results

2017 IEEE 3rd International Forum on Research and Technologies for Society and Industry (RTSI), 2017
In this paper, we explore the possibility to exploit GEOBIA concepts for extracting features from multitemporal SAR images. The proposed processing chain is feed by the recently introduced products of the Level-1a and Level-1β families and aims at providing an unsupervised tool for information extraction particularly oriented toward the end-user ...
