  • Breadth of GIS science capabilities aiding Hawaiʻi Wildfire response

    A combined federal, state, and local disaster such as the 2023 Hawaiʻi Wildfire mission has a lot of moving parts. There are temporary power, critical public facility, temporary housing, and debris assessment and removal missions. All of the data reporting the progress of these missions has to be tracked. For the U.S. Army Corps of Engineers, the way to do that is by using geographic information science systems, or GIS. USACE is using GIS data to synthesize an abundance of data to arrive at an overall picture of the status of the mission to keep everyone involved as informed as possible. “We have used the ESRI enterprise to create and produce data that can illustrate our mission both spatially and report instantly,” said Kihei, Hawaiʻi, Recovery Field Office GIS analyst Lisa Hook. “The data created populates databases I use to display on maps that are used for briefing and tracking of numbers.”

  • Reproducibility Assessment and Uncertainty Quantification in Subjective Dust Source Mapping

    Abstract: Accurate dust-source characterizations are critical for effectively modeling dust storms. A previous study developed an approach to manually map dust plume-head point sources in a geographic information system (GIS) framework using Moderate Resolution Imaging Spectroradiometer (MODIS) imagery processed through dust-enhancement algorithms. With this technique, the location of a dust source is digitized and recorded if an analyst observes an unobscured plume head in the imagery. Because airborne dust must be sufficiently elevated for overland dust-enhancement algorithms to work, this technique may include up to 10 km in digitized dust-source location error due to downwind advection. However, the potential for error in this method due to analyst subjectivity has never been formally quantified. In this study, we evaluate a version of the methodology adapted to better enable reproducibility assessments amongst multiple analysts to determine the role of analyst subjectivity on recorded dust source location error. Four analysts individually mapped dust plumes in Southwest Asia and Northwest Africa using five years of MODIS imagery collected from 15 May to 31 August. A plume-source location is considered reproducible if the maximum distance between the analyst point-source markers for a single plume is ≤10 km. Results suggest analyst marker placement is reproducible; however, additional analyst subjectivity-induced error (7 km determined in this study) should be considered to fully characterize locational uncertainty. Additionally, most of the identified plume heads (> 90%) were not marked by all participating analysts, which indicates dust source maps generated using this technique may differ substantially between users.

  • USACE Vicksburg District announces launch of Bayou Bodcau online map

  • Teamwork and Technology: Game changers for the U.S. Army Corps of Engineers

    Teamwork is the cohesive bond which unites the Corps. Whether it be engineering solutions or disaster response. This year’s hurricane season tested the USACE’s mission set of supporting the Department of Homeland Security and FEMA. The Corps assists FEMA’s emergency support function #3 (ESF-3) mission by providing services, technical assistance, engineering expertise, construction management and other support functions to prepare for, respond to and recover from disasters or incidents. Hurricane Florence in early September provided the conduit for the Corps to come together and provide not only boots-on-the-ground assistance, but to offer their technological expertise. Geographic information systems (GIS) and the USACE’s Modeling, Mapping and Consequences Production Center (MMC) were two entities that the Corps utilized during this year’s hurricane season.
