 Mapping Damages Caused by the October 2003 Wildfires in California Track: Environmental Management Author(s): Louis Demargne, Mitch Jordan In October 2003, California suffered one of the worst and deadliest wildfires in its history. The fires raged through more than 300,000 acres from San Diego to Ventura County. EarthData, in coordination with Esri and Horizons, was tasked with the collection of aerial imagery for assessment and mapping of damages to support rapid response and recovery efforts. Within 14 days, EarthData and Horizons acquired color-infrared imagery with ADS40 digital sensors over the worst affected areas totaling 3,143 square miles. ISTAR-derived orthoimages and digital elevation models (DEM) were delivered to Esri within 4 weeks of acquisition. State and local authorities had immediate access to these map products through a website linked to an ArcSDE database set up by Esri. Local end-users and Esri used the orthoimages to map damages caused by the fires. The DEM was used for drainage analysis to assess the risk of mudslides over the scorched terrain.
