The Palisades Fire and the Eaton Fire\u2014both of which broke out in Los Angeles County on January 7 and burned for weeks, fueled by powerful Santa Ana winds and extended drought conditions\u2014destroyed or damaged more than 16,000 homes and other structures, according to nonprofit news organization CalMatters.\r\n\r\nAs the fires burned out of control, agencies on the ground were getting help from GIS and satellite imagery to allocate resources as effectively as possible, prioritize areas in need, and expedite relief to affected communities. In particular, Esri partner ICEYE, which operates the world\u2019s largest synthetic aperture radar (SAR) satellite constellation, quickly delivered radar-based building-damage analysis to federal, state, and local organizations fighting the fires and providing emergency services. This allowed those organizations to understand how the fires were evolving and begin early damage assessments."},{"acf_fc_layout":"image","image":739912,"image_position":"right","orientation":"horizontal","hyperlink":""},{"acf_fc_layout":"content","content":"\u201cWith the fires in Los Angeles, there was a massive data gap. Agencies couldn\u2019t fly because of the persistent high winds, and they couldn\u2019t see through the smoke or as the fires burned during the night,\u201d said Andy Read, ICEYE\u2019s vice president of government solutions. \u201cThat\u2019s where our technology stands out. Our satellites use radar imaging that can see through smoke, clouds, and at night. Our analysis team then delivers GIS-ready insights that help government agencies understand the damage at a structural level in near real time.\u201d"},{"acf_fc_layout":"content","content":"<h2>How Radar Helps Determine Destruction<\/h2>\r\nICEYE builds its own satellites, and because it has so many in orbit, the satellites can revisit the same areas frequently. This ensures reliable data collection during and immediately after natural disasters such as wildfires, floods, and hurricanes.\r\n\r\nSatellites that record optical imagery require sunlight, good weather, and no visual obstructions. But radar-based satellites like the ones ICEYE produces send radio waves down to Earth that bounce off objects, such as buildings and vegetation, and return pulses to the satellite. By measuring the time it takes for the pulses to return to the satellite, ICEYE can determine the locations of those objects and their distance from the satellite.\r\n\r\n\u201cThis means that ICEYE can deliver insight day or night, through clouds and smoke, and regardless of high winds that ground the planes and drones that record traditional aerial imagery,\u201d said Read.\r\n\r\nFor the recent fires in Los Angeles, the company deployed its Wildfire Insights service, which leverages a machine learning model to analyze rapidly acquired high-resolution imagery. The model, trained on historical wildfire events, picks up on the differences in return pulses for buildings that have been destroyed versus those that haven\u2019t been impacted."},{"acf_fc_layout":"image","image":739922,"image_position":"left","orientation":"horizontal","hyperlink":""},{"acf_fc_layout":"content","content":"<h2>Actionable Datasets Ready for Analysis<\/h2>\r\nThe imagery that ICEYE produces isn\u2019t delivered to its customers in a raw format. Rather, the imagery is packaged in ready-to-use geospatial datasets via Wildfire Insights, an always-on service that\u2019s part of ICEYE\u2019s portfolio of natural disaster analytical products. Agencies on the ground can then put these datasets directly into ArcGIS Online or ArcGIS Pro to create the geospatial products they need.\r\n\r\nThe way the service works is that at ICEYE, a team of meteorologists and geospatial and remote sensing experts continually monitor and analyze SAR imagery of wildfire events. Public safety agencies don\u2019t have to delineate areas of interest or request imagery acquisition timelines; ICEYE just has those ready to go as actionable geospatial datasets that are compatible with ArcGIS technology.\r\n\r\n\u201cAfter we collect the images, we instantly start to analyze them and build that geospatial dataset,\u201d Read explained. \u201cThen we deliver it seamlessly to the customer.\u201d\r\n\r\nAgencies can take the datasets, plug them into whichever ArcGIS products they\u2019re using, and create maps, dashboards, and other visualizations of the events they\u2019re managing.\r\n\r\n\u201cEvery one of the end users is probably doing something a little different with the datasets, whether they\u2019re using ArcGIS Pro to do some additional analysis or building dashboards to use internally,\u201d said Read.\r\n\r\nDuring Southern California\u2019s recent fires, federal, state, and local agencies used ICEYE\u2019s datasets to fill in data gaps and get baseline damage assessments for impacted neighborhoods, despite the challenging conditions. For the Palisades Fire, ICEYE acquired and delivered its first image within 24 hours of the first signs of smoke on the ground. The ICEYE team continued to provide updated results of impacted buildings for that fire twice daily while also imaging and analyzing the nearby Eaton and Hurst fires\u2014the latter of which was a smaller fire that broke out in northern Los Angeles County on January 7 as well.\r\n\r\nOne state-level organization that responded to the fires used the SAR data to quickly analyze burn scars and determine the extent and geographic distribution of impacted areas. The resultant damage assessments were then efficiently shared with local, state, and federal partners through ArcGIS Online and a dedicated collaboration hub. This streamlined approach ensured a common operational picture, enabling agencies across all levels of government to effectively coordinate resources and accelerate recovery efforts."},{"acf_fc_layout":"content","content":"<h2>Getting Ahead on Damage Assessments<\/h2>\r\nBeing able to start on damage assessments early is one powerful use case for ICEYE\u2019s imagery."},{"acf_fc_layout":"image","image":739932,"image_position":"right","orientation":"horizontal","hyperlink":""},{"acf_fc_layout":"content","content":"To conduct traditional damage assessments, public safety agency staff members typically go door-to-door gathering data about damaged and destroyed buildings. These surveys are time-consuming to perform and difficult, if not impossible, to do while wildfires are still burning in the vicinity.\r\n\r\nIn the case of the recent fires in California, high winds persisted for several days at a time, only to pick up again after brief reprieves. This impacted firefighting efforts and grounded traditional airborne assets, creating blind spots for first responders and damage assessors. Integrating ready-to-use SAR imagery datasets helped these agencies fill in some gaps while the fires still raged, significantly enhancing both speed and accuracy.\r\n\r\n\u201cWe were able to tell the story of what happened on the ground before they could get in to do assessments,\u201d said Read. \u201cWith Wildfire Insights, an agency\u2019s GIS team doesn\u2019t have to spend time analyzing the imagery to get answers. We\u2019re delivering actionable information through our geospatial datasets. This means agencies can respond decisively as the event is unfolding.\u201d\r\n\r\nThis is true for wildfires as well as other natural disasters such as floods and hurricanes. ICEYE\u2019s Flood Insights solution is used extensively to provide situational awareness during flood events and heavy storms."}],"references":null},"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v25.9 (Yoast SEO v25.9) - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>As Wildfires Raged, Satellite Imagery and GIS Helped Fill In Information Gaps | Spring 2025 | ArcNews<\/title>\n<meta name=\"description\" content=\"ICEYE\u2019s radar imaging can see through smoke, clouds, and at night.
