This is the exact url for the best shot:

HERE"S a little slice of it that is northern belize and partway down the coast.. 87k



Original Caption Released with Image:

Panama, Costa Rica, Nicaragua, El Salvador, Honduras, Guatemala, Belize,
southern Mexico and parts of Cuba and Jamaica are all seen in this image
from NASA's Shuttle Radar Topography Mission. The dominant feature of the
northern part of Central America is the Sierra Madre Range, spreading east
from Mexico between the narrow Pacific coastal plain and the limestone
lowland of the Yucatan Peninsula. Parallel hill ranges sweep across
Honduras and extend south, past the Caribbean Mosquito Coast to lakes
Managua and Nicaragua. The Cordillera Central rises to the south, gradually
descending to Lake Gatun and the Isthmus of Panama. A highly active
volcanic belt runs along the Pacific seaboard from Mexico to Costa Rica.
High-quality satellite imagery of Central America has, until now, been
difficult to obtain due to persistent cloud cover in this region of the
world. The ability of SRTM to penetrate clouds and make three-dimensional
measurements has allowed the generation of the first complete
high-resolution topographic map of the entire region. This map was used to
generate the image.

Two visualization methods were combined to produce the image: shading and
color coding of topographic height. The shade image was derived by
computing topographic slope in the north-south direction. Color coding is
directly related to topographic height, with green at the lower elevations,
rising through yellow, red, and magenta, to white at the highest elevations.

Elevation data used in this image were acquired by the Shuttle Radar
Topography Mission aboard the Space Shuttle Endeavour, launched on February
11, 2000. The mission used the same radar instrument that comprised the
Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar that flew twice
on the Space Shuttle Endeavour in 1994. The Shuttle Radar Topography
Mission was designed to collect three-dimensional measurements of the
Earth's surface. To collect the 3-D data, engineers added a 60-meter
(200-foot)-long mast, installed additional C-band and X-band antennas, and
improved tracking and navigation devices. The mission is a cooperative
project between NASA, the National Imagery and Mapping Agency of the U.S.
Department of Defense, and the German and Italian space agencies. It is
managed by NASA's Jet Propulsion Laboratory, Pasadena, Calif., for NASA's
Earth Science Enterprise, Washington, D.C.

Size: 1720 by 1670 kilometers (1068 by 1036 miles)
Location: 14.5 degrees North latitude, 85.0 degrees West longitude
Orientation: North toward the top
Image Data: Shaded and colored SRTM elevation model
Date Acquired: February 2000
