This repository provide the region partition data of Hong Kong.
The regions are manually demarcated, in the Hong Kong island and the Kowloon district, by selecting vertices and finding their coordinates in Google map. The connectivity among regions is also manually identified, based on the author's personal knowledge with the help of Google map.
The function of each region is also manually labeled, also based on the author's personal knowledge (and with Google map of course). The funciton of each region can be three types, namely the business area (B), the residential area, and the merchant area (M).
The number of restaurants in each region is another feature, obtained by extracting the data from OpenStreetMap (using the Python package osmnx).
The region partitioning results are recorded in the following files
- "polygon_verteces.csv": records the coordinates of the vertices of each polygon (each region)
- "polygon.csv": records the information of each region
- "edges.csv": records the links with a origin node and a destination node
The illustration of the partiioning results is as follows.
