How to delineate urban gravitational zones? GIS-based multicriteria decision analysis and Huff’s model in urban hierarchy modeling
研究结合Huff模型和GIS多准则决策分析，用95个标准为克罗地亚20个主要城市划定城市引力区，提出新的城市等级建模方法。
Urban gravitational zones (UGZ) are related to cities' functions and population size. In strategic regional territorial planning adequate tools and detailed data are rarely used. This issue is not foreign to Croatia and other countries. How should the UGZ be accurately delineated for each city? A combination of Huff's model and GIS-based multicriteria decision analysis (GIS-MCDA) was used to delineate UGZ. In total, 95 criteria grouped into ten functions were used. The research resulted in a new methodological framework for deriving the urban hierarchy model, a tool that allows automation and simplification of the GIS-MCDA, and an urban hierarchy model of 20 major cities in Croatia.
