Abstract:
Hurricane Irma impacted Florida, United States from September 10 to 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. This dataset is a 2018 inundation raster layer created to estimate the extent of cropland and pasture/hay inundated by flooding from Hurricane Irma. The study area was the state of Florida in the United States of America. Data represent cropland, inundated cropland, pasture/hay, inundated pasture/hay, water bodies, and other land. The official website <https://www.nass.usda.gov/Research_and_Science/Disaster-Analysis/> provides disaster assessments in geospatial data format, reports, and metadata as available. 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.

The Disaster Analysis products retain the spatial attributes of the underlying Cropland Data Layer and its input imagery. The Landsat 8 OLI/TIRS imagery is obtained via download from the USGS Global Visualization Viewer (Glovis) website <https://glovis.usgs.gov/>. Please reference the metadata on the Glovis website for each Landsat scene for positional accuracy. The majority of the Landsat data is available at Level 1T (precision and terrain corrected). The DEIMOS-1 and DMC-UK 2 imagery used in the production of the Cropland Data Layer is orthorectified to a radial root mean square error (RMSE) of approximately 10 meters.

Overview_Description:
Entity_and_Attribute_Overview:
Note of Caution: There are several causes for inundation/anomalous water, which could potentially include flooding, saturated fields from rainfall, ponding, or intentionally flooded rice and aquaculture fields. Sentinel-1A SAR data was used for pre- and post-flood analysis to identify areas of inundation after the hurricane. Areas of inundation are then intersected with cropland as identified in the NASS Cropland Data Layer (CDL). The areas of inundation are also intersected with pasture/hay as identified in the CDL and the 2011 USGS National Land Cover Database (NLCD).
