Digital map of water quality data measured along Kallang River and at Jurong Eco Garden
Source: Humanities Network
Data source 1: Earth Echo International
Data source 2: The Sustainable Learning Lab, NIE
Use cases:1. Use data along Kallang River to explore limitations in GI2. Use both sets of data to compare water quality at different sites3. Use the Jurong Eco Garden data to compare water quality across different years
Note:The digital map allows you to toggle these layers - reservoirs, waterways and other water bodies.When you conduct GI in future, you may get groups to upload data on the Earth Echo International site.
