      Title: 1976-2005 Official USDA Plant Hardiness Zone Map
      Geospatial_Data_Presentation_Form: vector digital data
  Description:
    Abstract:
      This data set represents the Approved USDA Plant Hardiness Zone Map for the 1976-2005 period in shapefile format. The data set was created by assembling high quality station data of 30-year mean annual extreme minimum temperatures, quality control checks of the station data, interpolation of that data using the PRISM modeling system, and conversion of model output to plant hardiness zones.
    Purpose:
      Develop an approved, updated USDA-ARS Plant Hardiness Zone Map (PHZM) with a goal of meeting modern standards of geostatistical analysis and data resolution.

    Data: GIS data such as grids and shapefiles may be downloaded by U.S. Government users for U.S. Government purposes only and may not be distributed to non-U.S. Governmental users. Non-U.S. Government users may obtain enhanced (high resolution) official USDA Plant Hardiness GIS data in shapefile and raster grid formats from Climate Source, Inc. (<http://www.climatesource.com/PHZM/gis_data.html>), subject to Climate Source terms of use. The USDA-ARS and OSU (Oregon State University) logos must be prominently displayed on any maps derived from the GIS datasets, and USDA-ARS and OSU must be acknowledged on any derived datasets. The data may not be altered in any way without an explicit and prominently displayed disclaimer that the map is not the official USDA Plant Hardiness Zone Map, and USDA-ARS and OSU logos must not be displayed in the modified version.
