Identifying Generalizable Image Segmentation Parameters for Urban Land Cover Mapping through Meta-Analysis and Regression Tree Modeling

Remote Sensing, 2018
The advent of very high resolution (VHR) satellite imagery and the development of Geographic Object-Based Image Analysis (GEOBIA) have led to many new opportunities for fine-scale land cover mapping, especially in urban areas.

SOIL SEALING AND LAND USE CHANGE DETECTION APPLYING GEOGRAPHIC OBJECT BASED IMAGE ANALYSIS (GEOBIA) TECHNIQUE

, 2013
Land use and land cover change analysis is now a mature area of study but it is still important to monitor these changes and their subsequent impacts on ecosystem functions. The rate of Land use and land cover change is much larger than ever recorded previously, with quick changes to ecosystems taking place at local to global scales.

Introducing GEOBIA to Landscape Imageability Assessment: A Multi-Temporal Case Study of the Nature Reserve “Kózki”, Poland

Remote Sensing, 2020
Geographic object-based image analysis (GEOBIA) is a primary remote sensing tool utilized in land-cover mapping and change detection. Land-cover patches are the primary data source for landscape metrics and ecological indicator calculations; however ...
