Session 3: Demo of Geographic Information System (GIS)

Geographic Information Systems (GIS) take the data from your database and shows it to you on a map. It can do this when some of the fields in your database tables have locational information, such as addresses or country codes, which allow the data to be referenced on a map.

The Hong Kong government provides online maps with demographic information on the entire population, as well as district-by-district.


GIS can make it easier for you to see patterns that are related to a geographical location. For example, which districts in Hong Kong have the highest monthly income ? Which districts have the largest number of people in a household ? This can help businesses decide where to open new customer service centers, new store branches, or assign salespeople.
