Disaster Analysis 2017

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.


Northern California Wildfires – Wine Country (October 2017)

A series of wildfires broke out in Northern California in October 2017. Wildfires included the Atlas, Nuns, Tubbs, Pocket, and Redwood wildfires which occurred between October 8, 2017 and October 31, 2017. The United States Department of Agriculture's National Agricultural Statistics Service (NASS) responded to inquiries regarding the extent of cropland, specifically grapes, affected by the fires in near real-time. Active fire location data from USDA Forest Service Remote Sensing Applications Center and Cal Fire, along with the NASS Cropland Data Layer, were used to determine fire burn scars in the Mendocino, Sonoma, and Napa Counties, California. This analysis was completed and distributed to the Agricultural Statistics Board on October 19, 2017.

Hurricane Irma (September 2017)

Hurricane Irma impacted Florida, United States from September 10 – 13, 2017. The United States Department of Agriculture's National Agricultural Statistics Service (NASS) responded to various inquiries regarding the extent of flooding from Hurricane Irma over both cultivated land and pasture/hay in near real-time. Consequently, a 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.

Hurricane Harvey (August 2017)

Hurricane Harvey struck areas of Texas and Louisiana, United States from August 25 thru August 31, 2017. The United States Department of Agriculture's National Agricultural Statistics Service (NASS) responded to several inquiries regarding the extent of flooding due to Hurricane Harvey 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.
