The Trust for Public Land developed the 'Urban Heat Risk Explorer App' as a prototype template for the 2014 Esri Climate Resilience App Challenge. The app can be used by cities to help prepare for, respond to and recover from extreme heat events. We used ESRI's beta ArcGIS WebApp Builder to develop our App. This template allowed us to customize our application to be scalable, nimble and replicable. Using this framework, we created a custom widget using JavaScript and HTML. The app can be viewed on a desktop, tablet or mobile phone.

Three cities are included in the prototype version of the app: Chicago, New York and Los Angeles.There are 6 "heat risk factors" to explore:
- day time urban heat islands
- night time urban heat islands
- impervious cover
- tree canopy
- cooling stations
- live current and forecasted temperature

This application can help us better understand heat risks in our cities and communicate with citizens about ways they can protect themselves during extreme heat events. Tap on the following link to view the Urban Heat Risk application:
