The Hong Kong Tear Gas Heat Map

Currently the map is showing a lot of activity around the Hong Kong Polytechnic University, where police have trapped hundreds of activists. The police have today been firing tear gas canisters at demonstrators who have gathered to protest at the police siege of the campus. Just yesterday the creators of the crowdsourced Hong Kong police tracking map, released a heat-map visualizing the locations where tear gas has been deployed in Hong Kong from August 5th to November 15th. is a crowdsourced map which reports the live position of the police in Hong Kong. On the map different emojis are used to show the location of the police across the city. Registered users can use the Telegram messaging application to report locations where the police are currently using violence against protesters. The application is widely used by Hong Kong residents who wish to avoid the violent clashes between the police and protesters in the city.

The Tear Gas Deployed in Hong Kong static map is a crowdsourced map showing where the Hong Kong police have fired tear gas. It is important to note that the heat-map doesn't show the actual number of tear gas canisters fired by the police. The heat-map intensity is instead based on the numbers of users who have reported a tear gas canister fired at a location. It is still useful therefore in helping to identify the locations in Hong Kong which have witnessed the most violent clashes between the police and pro-democracy protesters.
