National Agricultural Imagery Program (NAIP), Minnesota, 2013, Digital Orthorectified Images (DOQ)
Dataset Identification:
Resource Abstract:
This data set contains 4-band natural color and false color infrared imagery from the National Agricultural Imagery Program
(NAIP). 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 source files are 1 meter
ground sample distance (GSD) ortho imagery rectified to a horizontal accuracy of within +/- 6 meters of reference digital
ortho quarter quads (DOQQ's) from the National Digital Ortho Program (NDOP) or from NAIP. 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. NAIP imagery is formatted to the
UTM coordinate system using NAD83. NAIP imagery may contain as much as 10% cloud cover per tile. The natural color county
mosaic files downloadable from the USDA NRCS Geospatial Data Gateway were generated by compressing NAIP imagery that cover
the county extent. MrSID compression was used. Target values for the compression ratio are (15:1). (Note: The Minnesota Geospatial
Information Office (MnGeo) has created this metadata record to describe the entire NAIP 2013 dataset, using information from
Farm Service Agency metadata. Each natural color county file available from the USDA NRCS Geospatial Data Gateway is accompanied
by the original FSA metadata for that county.)

purpose:
NAIP imagery is available for distribution within 60 days of the end of a flying season and is intended to provide current
information of agricultural conditions in support of USDA farm programs. For USDA Farm Service Agency, the 1 meter GSD product
provides an ortho image base for Common Land Unit boundaries and other data sets. The 1 meter NAIP imagery is generally acquired
in projects covering full states in cooperation with state government and other federal agencies who use the imagery for a
variety of purposes including land use planning and natural resource assessment. NAIP is also used for disaster response often
providing the most current pre-event imagery.

Use Constraints: The Aerial Photography Field Office asks to be credited in derived products. If defects are found in the
NAIP imagery during the warranty period such as horizontal offsets, replacement imagery may be provided. Imagery containing
defects that require the acquisition of new imagery, such as excessive cloud cover, specular reflectance, etc., will not be
replaced within a NAIP project year. Redistribution conditions: In obtaining this data from MnGeo, it is understood that you
and/or your organization have the right to use it for any purpose. If you modify it, you are encouraged to apply responsible
best practices by documenting those changes in a metadata record. If you transmit or provide the data to another user, it
is your responsibility to provide appropriate content, limitation, warranty and liability information as you see fit.

Ordering Instructions
Ordering Instructions: The imagery is available free online by clicking below after Online Linkage. This link will take you
to a webpage that contains direct links to: 1. View the files seamlessly via a WMS service without having to download the
files. They are available as two separate layers: a natural color version and a color infrared version. 2. Download each county
file in MrSID format (natural color only, does not include color infrared Band 4) and accompanying seamline shapefile from
the U.S. Dept. of Agriculture, Natural Resources Conservation Service's Geospatial Data Gateway site: http://datagateway.nrcs.usda.gov
The files will be in either UTM zone 14 or 15, depending on which zone covers the majority of the county. 3. To obtain just
the seamline shapefiles (1 per county) that include the date that the photos were flown, see: http://www.mngeo.state.mn.us/chouse/metadata/naip13_date.html
notes: This metadata was automatically generated from the Minnesota Geographic Metadata Guidelines standard (version 1.2) using the
2012-06-20T17:21:00 version of the FGDC RSE to ISO 19115-2 transform.
