Smart urban renewal management of heritage buildings based on POI and GIS: macau’s largo boundary space

The "Largo", a unique type of urban boundary space exclusive to Macau, is a spatial product formed after the fusion of Chinese and Western cultures, with spatial functions and place meanings that are particularly distinctive. The Largo refers to the transitional space between buildings or roads, forming a boundary space between them. This paper quantitatively analyzes the characteristics of frontier spaces based on their different attributes using GIS and POI analysis methods. Furthermore, it examines the current situation quantitatively. Finally, an optimization strategy is proposed for strengthening rigid boundaries and implementing flexible designs for different types of frontier spaces. This provides a reference strategy for smart management of heritage buildings and smart urban renewal in Macau.
