Automated flood detection from Sentinel-1 GRD time series using Bayesian analysis for change point problems
Narumasa Tsutsumida, Tomohiro Tanaka, Nifat Sultana
Current Synthetic Aperture Radar (SAR)-based flood detection methods face critical limitations that hinder operational deployment. Supervised learning approaches require extensive…
A Bayesian Inference Approach for Reducing Inter-Investigator Variability in Sampling-Based Land Cover Classification
Narumasa Tsutsumida, Akira Kato
Land cover classification faces persistent challenges with inter-investigator variability and salt-and-pepper noise. Although cloud platforms such as Google Earth Engine have made…
gwpcorMapper: an interactive mapping tool for exploring geographically weighted correlation and partial correlation in high-dimensional geospatial datasets
Joseph Emile Honour Percival, Narumasa Tsutsumida, Daisuke Murakami +2
Exploratory spatial data analysis (ESDA) plays a key role in research that includes geographic data. In ESDA, analysts often want to be able to visualize observations and local rel…
Investigating Spatial Error Structures in Continuous Raster Data
Narumasa Tsutsumida, Pedro Rodríguez-Veiga, Paul Harris +2
The objective of this study is to investigate spatial structures of error in the assessment of continuous raster data. The use of conventional diagnostics of error often overlooks…
