LANDFIRE 2014 v.1.4.0

Landfire 2014 v1.4.0 data for the continental United States, Alaska, and Hawaii were delivered in 2017. Landfire 2014 v1.4.0 is a vegetation and fuels mapping effort to update the base product suite. LF 2014 incorporates landscape change and disturbances, such as wildland fire, fuel and vegetation treatments, insects and disease, storm damage, and invasive plants that occurred in 2013 and 2014.

This data is the default data source used by WFDSS for fire behavior analysis, and when users query fuels and topographic data on incident and intelligence map displays. Users can change the default selection on the Incident Information page, if they choose. If an analyst chooses a different data source for an analysis, the chosen data source would override the incident default data source for that analysis only.

This update includes:

The LF 2014 update also:

The LF 2014 update strategy applies a consistent approach to combine geospatial data depicting areas of disturbance with Remote Sensing of Landscape Change (RSLC) derived data to develop the disturbance layers. Data from combinations of Landsat satellite imagery, fire program data (e.g., Monitoring Trends in Burn Severity (MTBS)), cooperator-provided field data, and other ancillary data (e.g., Protected Area Database (PAD)) are used to locate and characterize large wildfires.

Landscape Data Introduction

WFDSS uses the aspect, slope, elevation, fuel model, canopy cover, canopy base height (CBH), canopy bulk density (CBD), and stand height layers to a create landscape file that displays fuels, topography and canopy information simultaneously (go to the Intelligence or Incidents - Situation page, or for fire behavior modeling, go to the Analysis page). Similar to the LANDFIRE data, all values are measured with the metric system:
