This spectacular image of the Mall area was acquired on Saturday, April 1, 2000 by Space Imaging's IKONOS sensor. Here we are moving across the Mall, from west to east and we will pause over the Capitol Building. Let's just sit back for a few seconds and enjoy the view. We will then gradually pull back from this highly localized view from space, to obtain a more regional perspective provided by Landsat 7. This regional view permits us to follow the entire length of the Potomac River, from its headwaters in the Shenandoahs, until it flows into the Chesapeake Bay. We can also see the full extent of the Chesapeake and Delaware Bays as they flow into the Atlantic. We will continue to pull back farther to obtain more continental and global views of the Earth as provided by a new instrument known as MODIS, or the Moderate Resolution Imaging Spectroradiometer, the primary instrument on the Terra spacecraft. Finally, we rotate the Earth so as to see a representation of the Earth's stable light sources, as derived from DMSP satellites. (Note: This animation is a precursor to the Great Zooms. It is based on the same concept and data sources, but is somewhat less polished, particularly in the area of color matching.)
Pan across the mall in Washington, DC using 1 meter
resolution IKONOS data, followed by a zoom out to space using 30 meter
resolution data from Landsat 7 and 250 meter and 8 kilometer resolution Terra
MODIS data. A final rotation of the Earth shows data of stable
light sources from DMSP data.
