Home > Data > Maryland Imagery - MODIS Image of the Week

The following are the MODIS images of the Week for 2011. The Moderate Resolution Imaging Spectroradiometer (MODIS) is an instrument (sensor) aboard the Terra and Aqua satellites. Terra's orbit around the Earth is timed so that it passes from north to south across the equator in the morning. Aqua passes south to north over the equator in the afternoon. Terra MODIS and Aqua MODIS view the entire Earth's surface every 1 to 2 days, acquiring data in 36 spectral bands, or groups of wavelengths, at 250 meter, 1,000 meter, 2,000 meter, and 4,000 meter resolutions. Additional information about MODIS is available at http://modis.gsfc.nasa.gov/.

The images available for download are the "best" 250 meter resolution true color (MODIS bands 1, 4, 3) image in .jpg format from either instrument observed during a week beginning on Sunday. All of the .jpg images are 1187 x 750 pixels in size. Percent cloud cover is the determining factor for selection of the best image during any given week. Cloud free (0% cloud cover) images are noted. One of the more conspicuous features on many of these images is the sedimentation of the Upper Chesapeake Bay and several Chesapeake Bay estuaries (the Potomac River and Rappahannock River). The MODIS imagery for Maryland is made available from WisconsinView. We sincerely appreciate the assistance of a fellow AmericaView Consortium member in providing us a daily feed of MODIS subset products for Maryland.
