Airborne Infrared Perimeters of the Rim Fire (2013) and Dixie Fire (2021)

This repository contains the shapefiles of airborne infrared-derived fire perimeters of the two California wildland fires (the 2013 Rim Fire and the 2021 Dixie Fire) used as examples to produce fire progression maps in the manuscript "Consistency in Pyrocartography Starts With Color" by Hatchett (2025). The infrared perimeters for each fire were acquired from the National Interagency Fire Center's (NIFC) File Transfer Protocol Server (https://ftp.wildfire.gov). Files were initially downloaded in .kmz formats and converted to shapefiles using QGIS. Because not all days of a wildland fire receive aerial mapping due to aircraft availability or weather conditions (or for other reasons), all available near-daily perimeters were acquired, processed, and aggregated into an individual zip file for each fire. The original file names were maintained as acquired from the NIFC database.
