The USDA NASS monitors the impact of natural disasters on US agriculture in near real-time using remotely sensed data and geospatial techniques. The first test case is detailed in the following papers <https://www.nass.usda.gov/Research_and_Science/Disaster-Analysis/2018/Hurricane-Michael/Flood_Monitoring_Methodology_Paper.pdf> and <https://www.nass.usda.gov/Research_and_Science/Cropland/docs/Boryan_IGARSS2018%20_Flood.pdf>.

Description:
Abstract:
This dataset is a 2020 vector layer created to estimate the extent of cropland affected by wind damage from the derecho on August 10, 2020 in Iowa, United States. Data represent estimated peak wind gust polygons over the region for this date. These polygons were derived by NASS from a combination of several wind input datasets listed below. Polygon data were intersected with the 2019 Cropland Data Layer (CDL) and compared with 2019 official NASS estimates. The official website <https://www.nass.usda.gov/Research_and_Science/Disaster-Analysis/> provides a report with estimates of acres within the fire perimeter based on last year's Cropland Data Layer and is available for external release and download. These data are not official NASS estimates.
Purpose:
Agricultural disaster monitoring is important for food security and economic stability. Using remotely sensed data and geospatial techniques provides an additional tool for the USDA NASS to use in evaluating a disaster's impact on US agriculture.
