GIS Improvement in Wildfire Management

California’s state parks have initiated a cutting-edge approach to firefighting through the implementation of Geographic Information Systems (GIS) technology to enhance wildfire response. Nathanial Wigington from READ/REAF has outlined the transformative impact this digital mapping technology has on emergency management, especially within California State Parks.

Revolutionizing Emergency Management

The integration of digital mapping and geospatial technologies has changed the landscape of wildfire response and resource protection in California State Parks. By utilizing advanced tools and techniques, the parks aim to expedite and refine emergency management efforts. Key applications include field mapping GIS applications, Unmanned Aerial Systems (UAS) operations, and monitoring post-fire vegetation burn severity using resources like Sentinel-2 from NASA.

Resource Advisors (READs/REAFs)

Resource Advisors, such as READs and REAFs, play a crucial role in safeguarding the resources of California State Parks during emergencies. They act as vital liaisons between emergency response teams and park management, ensuring effective response measures while protecting sensitive areas. Their specialized training combines resource protection practices with emergency response protocols, allowing for rapid deployment under challenging circumstances. Regular field exercises and ongoing certification maintain their readiness for action.

GIS Revolution in Resource Management

The adoption of digital systems for spatial data collection and analysis marks a significant shift in resource management. Previously reliant on paper maps and handheld GPS units, field teams have transitioned to using tools like Field Maps and ArcGIS Online. This digital transformation has streamlined workflows, enabling faster data sharing and improved decision-making in real time. The resulting enhancements in efficiency turn data processing from days into mere hours.

Case Study: The Palisades Fire

A case in point showcasing the effectiveness of GIS technology is the Palisades Fire that erupted in January 2025. This major wildfire affected over 23,500 acres, primarily in the Santa Monica Mountains region, necessitating a robust response from over 50 Resource Advisors from various agencies, including the Department of Parks & Recreation and the US Geological Survey. GIS tools enabled informed decision-making, targeted resource allocation, and protection of critical habitats and cultural sites during the incident.

Advanced GIS Tools in Action

The use of applications like ArcGIS has facilitated smoother coordination among teams. Through these platforms, field teams can validate real-time data and quickly disseminate this information, which is essential for managing wildfire damage and implementation of repairs. The emphasis on improving communication through these tools fosters an environment for enhanced situational awareness and rapid decision-making.

Palisades Fire Monitoring Applications

Multiple ArcGIS applications were developed for monitoring both the current status and post-fire recovery efforts in relation to the Palisades Fire. Features of these applications include tracking suppression repairs on state properties, updating staff preparedness for future hazards, and addressing infrastructure concerns stemming from wildfire damage.

Georeferenced Paper Maps

To complement digital mapping, georeferenced paper maps are utilized for navigation with apps such as Avenza PDF Maps. These maps are distributed daily to Resource Advisors and park managers, providing them with critical geographical details and enabling exploration without needing a data connection. They aid in locating essential landmarks crucial for on-the-ground operations.

Future of GIS in Wildfire Management

The landscape of wildfire management is continuously evolving with advancements in GIS technology. Key improvements include data integration for comprehensive fire behavior predictions, mobile technology facilitating real-time updates, and standardized protocols that enhance inter-agency cooperation. This evolution has drastically improved response times and accuracy in predicting fire behavior, contributing to overall safety and resource management efficiency.
