      Title: NAIP 2009 - Index of Source Acquisition Dates
      Geospatial_Data_Presentation_Form: vector digital data
  Description:
    Abstract: This data set contains polygons delineating the seams boundary between acquired imagery used in the creation of DOQQs and compressed county mosaic (CCM).  The DOQQ and CCM products were created from imagery acquired in the National Agriculture Imagery Program (NAIP).  These seam polygons can be used as a tool in determining the image source and date of each portion of the DOQQ or the CCM. The NAIP acquires digital ortho imagery during the agricultural growing seasons in the continental U.S.. A primary goal of the NAIP program is to enable availability of ortho imagery within one year of acquisition. The NAIP provides two main products: 1 meter ground sample distance (GSD) ortho imagery rectified to a horizontal accuracy within +/- 5 meters of reference digital ortho quarter quads (DOQQ's) from the National Digital Ortho Program (NDOP), or from the National Agriculture Imagery Program (NAIP); 1 meter GSD ortho imagery rectified within +/- 6 meters to true ground.  The tiling format of NAIP imagery is based on a 3.75' x 3.75' quarter quadrangle with a 300 meter buffer on all four sides.  The NAIP quarter quads are formatted to the UTM coordinate system using the North American Datum of 1983 (NAD83).
    Purpose: This index will aid USDA Agencies in identifying and delineating source acquisition date boundaries for the compressed county mosaic as they administer USDA programs for their customers.
    Supplemental_Information: This index may be in a different projection/coordinate system than the imagery.
