The exact recognizable proof of metropolitan useful regions is of incredible importance for advancing metropolitan spatial construction, normally assigning spatial components, and advancing the supportable advancement of the city. This paper proposes a technique to definitively distinguish metropolitan practical regions by coupling Open Street Map (OSM) and Point of Interest (POI) information. It takes the focal metropolitan area of Hangzhou as a contextual analysis to investigate the spatial dissemination attributes of the practical regions. The outcomes show that: the focal metropolitan areas of Hangzhou are partitioned into 21 practical regions (6 single utilitarian regions, 14 blended useful regions and 1 exhaustive useful region). The single utilitarian regions and the blended practical regions show the topographical conveyance attribut of the circling definition, and that signifies "Center outskirts" separation is self-evident, and the extensive useful region is generally dissipated. The blended level of territorial capacity in with environmental capacity and creation work is low while far reaching useful regions are normally connected with higher potential and imperativeness. An examination of spatial distribution patterns, development trends, and the hierarchy of different social roles can reveal the urban structures. The efficiency of the proposed strategy is supported by the findings of a case study conducted for Munich.
