DOI: 10.1080/24694452.2025.2511945
Abstract: Geographical analysis often faces challenges in selecting appropriate analysis units due to spatial heterogeneity, autocorrelation, and the modifiable areal unit problem (MAUP). Traditional spatial partitioning or aggregation methods using grids, administrative zones, and traffic analysis… read more here.
