CropScape Demo Innovations to Minimize Crop Loss in a Changing Climate Rick Mueller National Agricultural Statistics Service February 24, 2012 CropScape • A web service based interactive map visualization, dissemination and querying system for U.S. cropland – No burden on users • • • • No client software development & installation No special software tools needed Data mashable Democratization of data – Equitable information access, automatic timely delivery, and geospatial navigation • Collaboration with George Mason University/Center for Spatial Information Science and Systems (CSISS) http://nassgeodata.gmu.edu/CropScape 2008 – 2011 National Cropland Data Layers ~ 9 billion pixels/year! Harmonize ALL historical CDL products to standard: color scheme, categories, projection, metadata. 1997 – 2007 Cropland Data Layers ’06-’07 ’07 ’97-’07 ’06-’07 ’07 ’03-’07 ’06-‘07 ’01-’07 ’07 ’00-’07 ’99-’07 ’00-’07 ’06-’07 ’06-’07 ’07 ’06-07 ’97-’07 ’99-’07 ’04-’07 Harmonize ALL historical CDL products to standard: color scheme, categories, projection, metadata. ’04 CropScape Components Data View Pixel Query Navigation Stats/Change AOI Query Print/Download Help Overview Social Media Select an Area of Interest By State By State & ASD Select an Area of Interest By State, District & County By Rectangle, Circle, or Polygon Crop Statistics Pixel counting is usually downward biased when compared to official estimates. Counting pixels and multiplying by the area of each pixel will result in biased area estimates and should be considered raw numbers needing bias correction. Official crop acreage estimates are available at http://www.nass.usda.gov/.
