The USGS has contracted with SPOT Image Corporation to acquire and provide Satellite Pour l'Observation de la Terre (SPOT) satellite data for November 2009 through January 2013. Under the North America Data Buy (NADB) agreements, SPOT Image will provide moderate-resolution data from their SPOT 4 and 5 satellites over the conterminous United States and parts of Canada and Mexico through the receiving capabilities at the USGS EROS Center. The French space agency, Centre National d'Etudes Spatiales (CNES), owns and operates the SPOT satellite system. SPOT Image Corporation is a subsidiary of the SPOT Image group, which provides worldwide distribution of their imagery.
Under the licensing arrangements of the North America Data Buy contract, access is limited to U.S. Federal civil Government agency users and U.S. State and local government users. The 2011 contract expands usage to include U.S. tribal governments. Qualified users must be logged in to EarthExplorer to gain access to this dataset. An explanation of data restrictions and limitations is displayed when accessing these collections and must be agreed upon before gaining access to these data.
The USGS SPOT 4 and 5 datasets provide North American coverage between 53° north latitude and 23.5° north latitude in calendar year 2010. The coverage for 2011 extends from 55° north latitude to 23.5° north latitude.
Both SPOT satellites carry imaging instruments that operate with panchromatic and multispectral sensors. The SPOT 4 payload includes two High Resolution Visible and Infrared (HRVIR) sensors, and SPOT 5 utilizes two High Resolution Geometric (HRG) instruments. Each sensor has a swath of 60 km and has an oblique viewing capability of 27° on each side of vertical. The sensors can operate independently to observe separate targets or in tandem to cover a larger swath in a single pass. Each scene in this collection is approximately 60 km by 60 km and is referenced to World Geodetic System 84 (WGS 84) datum.

*near infrared (NIR) and shortwave infrared (SWIR)
**The resolution of the SPOT 5 multispectral scene is 10 m.
All SPOT scenes acquired via the NADB are initially processed to Level 1A (L1A) by SPOT Image Corporation and are made accessible to authorized users through EarthExplorer. In addition to the L1A dataset, USGS EROS also offers Level 1Gst (L1Gst), Level 1T (L1T), Full Resolution Browse, and GIS Ready Bundle products.
DIMAP typically contains the following files:
IMAGERY.TIF = image file in GeoTIFF format
METADATA.DIM = XML metadata file
ICON.JPG = Image.icon
PREVIEW.JPG = Quicklook
STYLE.XSL = Style sheet used to apply HTML formatting to XML file
SPOT 4 and 5 products are available for download in both panchromatic and multispectral modes. A panchromatic scene is a single-band image, and a color product is derived from the multispectral bands. File sizes for L1A, L1Gst, and L1T images may vary from 30 to 250 megabytes (MB) depending on imaging mode and level of processing. File sizes for Full Resolution Browse and GIS Ready Bundle products may vary from 1 to 5 MB depending on imaging mode.
This collection of SPOT 4 and 5 data is subject to the terms and conditions stated in the North America Data Buy agreement between SPOT Image and the USGS.
Qualified users are recognized through the EarthExplorer registration process and must be logged in to gain access to this dataset. Users must accept the restrictions stated in the End User License Agreement (EULA) in order to download data.
