Costs of human-ignited wildfires in the U.S. (2001-2015)-from the Wildland-Urban Interface to wildlands ===================================================================================== All R code to run the analysis can be found in src/R/analysis

1. Run 1_create_folder.R

2. Run 2_get_data.R to download, unpack, and organize all neccessary files. The spatial data that are fetched are:

• Contiguous US state boundaries
• Level 1,2,3 ecoregions
• Wildland-urban interface (2010)
• Fire Program Analysis Fire-Occurrence Database (1992-2015)
• Monitoring trends in burned severity (1984-2015)

3. Run 3_clean_data.R. All spatial database processing is accomplished. All intermediate results are written out so this step needs to be run only once. This particular script is extremely memory intensive due to the large WUI shapfiles and FPA-FOD database. Because of this it can only be run on a 122 GB RAM EC2 instance on the Amazon Web Services.

4. Run 4_create_buffer.R.
