Western Wildfire Risk Explorer


Introduction

The Western Wildfire Risk Explorer (WWRE) is an online interactive map built using open source components. This application summarizes on a subwatershed level within national forest boundaries, the burn probability, conditional flame length, and flame length probability for each of 6 flame length classes. For more technical details, read the Western Wildfire Risk Explorer Technical Description.

The mean burn probability, conditional flame length, and flame length class probabilities were calculated for each subwatershed within the national forests. A separate report for each national forest in the west displays these values in graphical format. When the user selects the national forest from a dropdown list, the map will zoom to the extent of the national forest.

The WWRE user interface is built using open source components such as Ext JS, GeoExt, and OpenLayers. All layers come from web map services delivered using GeoServer.

Above the map is a dropdown list of 82 national forests in the west. The map automatically zooms to the selected national forest. The 'Subwatershed Report' link to the right of the dropdown list will open a report for the selected national forest. This report provides a table and charts to depict mean burn probability, conditional flame length, and flame length class probabilities by watershed. The calculated values use subwatershed boundaries clipped to the national forest.

The remaining user interface components are derived from the Open Source Cloud Map described here.
