================================================================================ DROUGHT.GOV DATA ================================================================================ Drought.gov processes data from multiple partners. This data is summarized into web-ready formats, map layers, and statistics shown throughout Drought.gov. The data is available from NOAA's National Centers for Environmental Information (NCEI) and the NOAA Open Data Dissemination program, which provides free unauthenticated public access via Google Cloud Storage (GCS). -------------------------------------------------------------------------------- DATA ACCESS & URL FORMATTING -------------------------------------------------------------------------------- To access the files via the public endpoint in Google Cloud Storage, modify the standard NCEI URLs as follows: * JSON Files: Replace: https://www.ncei.noaa.gov/pub/data/nidis/geojson/ With: https://storage.googleapis.com/noaa-nidis-drought-gov-data/current-conditions/json/v1/ * Map Tiles: Replace: https://www.ncei.noaa.gov/pub/data/nidis/tile/ With: https://storage.googleapis.com/noaa-nidis-drought-gov-data/current-conditions/tile/v1/ * JSON File Directory Browser: Use: https://console.cloud.google.com/storage/browser/noaa-nidis-drought-gov-data/current-conditions/json/v1 * Map Tile Directory Browser: Use: https://console.cloud.google.com/storage/browser/noaa-nidis-drought-gov-data/current-conditions/tile/v1/ Note: Logging into a Google account is required to use the storage browser. However, logging in is NOT required for direct public file access using the storage.googleapis.com URLs. -------------------------------------------------------------------------------- JSON / GEOJSON / TOPOJSON FILES -------------------------------------------------------------------------------- General statistics are available in JSON format, while point/line/polygon GIS data is available in GeoJSON and TopoJSON formats.
