Centamap (Chinese: 中原地圖) is a free web map service that displays maps of Hong Kong, launched in 1999. It obtains licensed map data from the Survey and Mapping Office of the Hong Kong Government. Centamap was developed by Centaline Property Agency at a cost of HK$6 million. The website was launched on 19 November 1999; within its first four days it had attracted 100,000-page views per day. At the time, it was one of two digital maps of Hong Kong that had been developed using map data from the government, the other being PCCW's YPmap. Centaline had intended to make money from the website using banner advertising, expecting revenue of $1–1.5 million a year. More information...
