Disaster Analysis 2018

NASS can now monitor agricultural disasters in near real-time and provide quantitative assessments using remotely sensed data and geospatial techniques. This page provides disaster assessments in geospatial data format, reports, and metadata as available. A flood monitoring methodology paper is located here.


Hurricane Michael (October 2018)

Hurricane Michael impacted areas of Florida, Georgia, Alabama, South Carolina and North Carolina, United States from October 10 - 12, 2018. The United States Department of Agriculture's National Agricultural Statistics Service (NASS) responded to inquiries regarding the extent of flooding from Hurricane Michael over agricultural land in near real-time. Consequently, a recently developed flood mapping procedure, based on Copernicus Sentinel-1 Synthetic Aperture Radar data and the NASS Cropland Data Layer was implemented in response to the flood event. The data, maps, and reports below identify the extent of inundation over cropland and pasture based on this analysis. The crop inundation layers are publically available for download.

Hurricane Florence (September 2018)

Hurricane Florence struck areas of Virginia, North Carolina, South Carolina, and Georgia, United States from September 14 – 19, 2018. The United States Department of Agriculture's National Agricultural Statistics Service (NASS) responded to inquiries regarding the extent of flooding from Hurricane Florence over agricultural land in near real-time. Consequently, a recently developed flood mapping procedure, based on Copernicus Sentinel-1 Synthetic Aperture Radar data and the NASS Cropland Data Layer, was implemented in response to the flood event. The data, maps, and reports below illustrate and estimate the extent of inundation over cropland and pasture based on this analysis. The crop inundation layers are publically available for download.

Oregon Substation Fire (July 2018)

The Oregon Substation Fire occurred from July 17, 2018 to July 22, 2018 in Wasco and Sherman Counties, Oregon (incident overview). The United States Department of Agriculture's National Agricultural Statistics Service (NASS) responded to inquiries regarding the extent of cropland affected by the fire in near real-time. Active fire location data from USDA Forest Service Remote Sensing Applications Center, along with the NASS Cropland Data Layer and daily MODIS Terra imagery from the Land Processes Distributed Active Archive Center (LP DAAC), were used to identify the fire burn scar. The report below includes estimates of acres within the fire perimeter based on the 2017 Cropland Data Layer and is available for external release and download.
