A quick overview of the latest (current) fire situation (last update: 16 May) and all previous days can be directly accessed at the Fire Monitoring, Mapping, and Modelling (FireM3) Project website (the FireM3 project is a collaboration of the Canadian Forest Service and the Canada Centre for Remote Sensing). Through the Map Link you can access daily hotspot images. An Internet Map Server, which is like a simple GIS running on the host computer, allows you to zoom in on any fire or other area of interest and view the image and map data at full (1km) resolution. You can also click on any fire and get information about that fire.
