Disaster Analysis

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 Fiona - September 2022

Hurricane Fiona was a powerful hurricane that caused widespread damage over portions of the Caribbean and Eastern Canada in mid-September 2022. It made landfall in Puerto Rico on September 16, 2022. The United States Department of Agriculture's National Agricultural Statistics Service (NASS) responded to inquiries regarding damage to agricultural land in Puerto Rico. Analysis was completed using several data products, including Sentinel-1A Synthetic Aperture Radar (SAR) data dated September 19-26, 2022. PlanetScope images acquired before and after the event and FEMA WAZE Alert for Puerto Rico Public data were used for validation. For this event, inundation raster files for the areas of interest are included for download.

The United States Department of Agriculture (USDA) National Agricultural Statistics Service (NASS) responded to inquiries regarding the extent of flooding over agricultural land in Missouri, Illinois, and Kentucky. Analysis completed using several freely available data products, including Sentinel-1 Synthetic Aperture Radar, Sentinel-2 Modified Normalized Water Index (MNDWI), soil moisture data from Crop-CASMA (Crop Condition and Soil Moisture Analytics), and the NASS 2021 Cropland Data Layer. For this event, inundation raster files for the areas of interest are available for download.

Texas Wildfires – March 2022

High winds, low humidity, and drought-parched grasses caused wildfires across the Southern Plains of the United States in mid-March 2022, including Texas. The United States Department of Agriculture's National Agricultural Statistics Service (NASS) responded to inquiries regarding the extent of agriculture affected by the Texas wildfires in near real-time. Wildfire perimeter location data was provided by the National Interagency Fire Center. False color composite images were generated from Sentinel-2 to represent pre- and post-fire images. The pre-fire image is a median image derived from January 1 through February 28 images and the post-fire image was derived from imagery dated March 20. Fire masks were derived from the MODIS Terra Thermal Anomalies & Fire Daily Global 1km Product dated March 17-21, 2022 to verify wildfire boundaries. Land cover information was derived from the NASS 2021 Cropland Data Layer.
