7-Eleven and Circle K are two major convenience store chains in Hong Kong. Where could you find more store in one chain compared to the other? And what is the magnitude of differences?
Note: Chinese version of this article is also available in my Medium (i.e. here!).
Hong Kong is packed with two major convenience store chains, 7-Eleven (7–11) and Circle K (OK). While there are nearly 1,000 7–11 stores, there are only 350 Circle K stores in the whole territory.

Are you interested to play and mess with the commute pattern dataset of Hong Kong? Want to select your area of focus without touching the dataset? Or, you are just looking for examples of web applications developed using Shiny? This is the article for you.
This article serves as a place to introduce the webpage I created for interactively visualising the commute pattern dataset. The webpage is created using Shiny and available at the following link:
There are more than 2.8 million workers with a fixed place of work in Hong Kong. What does the overall travel pattern from their home to the working place look like, when visualised? The location of the jobs and the living place of the workers are revealing the job-housing imbalance problem of the new towns of Hong Kong.
Here’s an O-D matrix showing the number of workers grouped by their living and working place in 2016¹. Each cell represents the number of workers living in that row and working in that column. Say, the number 48,647 in the top-left corner…
How the commuting patterns vary among the new towns in Hong Kong? Why are there more bus travellers or subway travellers in each new town? This article presents the dominate commuting type in the selected new towns. You could dig deeper into the design pattern of the new towns.
A year ago, I made a map and wrote an article to show the overall commute pattern of Hong Kong, aiming to show how dominant MTR is as a commuting transport. …
About 436,000 pedestrian walkway segments are scattered around the whole territory of Hong Kong. The distribution of both length and gradient are uneven. Most of them are on flat terrain and short paths between 0–20 m. There are around 333,800 normal footways, 27,500 crossings, 7,200 footbridge and 1,000 subway segments in the network. These numbers could help us get a rough image of the topology of the pedestrian network in Hong Kong.

How will be the urban land in Hong Kong flooded when sea level continues to rise? Here are several maps simulating the flooded area when sea level rises to a given level.
Sea level rising is never a new term for us. It is estimated that when we are still doing the “business-as-usual” scenario, more than 150 million people living on land will have their living place below high-tide line by 2050.
Mitigation and adaption are both essential to climate changes. Urban planners and designers have proposed several visions to adapt the expected increase amount of water running through the…
Are there any other ways to describe land utilisation of the city besides merely looking into the ubiquitous land utilisation maps and classification diagrams? I created a layer of hexagonal bins covering Hong Kong, then used it to count different types of land uses. These maps “with a little twist” provide a fresh way to look into land use distribution and presents an uncommon mapping technique of grouping data into regular grids.
Land use maps are, literally, thematic maps that draw the classified land resources/uses of the land. Among the 1100 sq.km. …
This article guides you on how to create an old-fashioned, pen-and-ink style map from scratch, quickly.
A short time ago, I worked on a static map presenting the ferry routes in Hong Kong for practising my GIS skills and for fun. Much like the other static maps, I need to find a place to document how this map is made for my reference. And, if possible, this could be used as some basic tutorials for students trying to make some “aesthetic” style map in ArcGIS.
This map is indeed just some tasks on data collection and symbology adjusting. In terms…
