The Panama Canal
This image shows a perspective view created by draping a Landsat image over the elevation framework
from an SRTM data set for the Panama Canal.
It was created from an original map produced from data obtained by NASA's
Shuttle Radar Topography Mission (SRTM). Using Google's free Picasa2 program, the
color, contrast, and lighting were enhanced to obtain the image above. The
original image can be viewed at the NASA link above.
This perspective view shows the Panama Canal with the Gulf of Panama in the foreground and
the Caribbean Sea in the distance. The canal runs northwest-southeast from the city of Colon
on the Atlantic side to Panama City on the Pacific side. Water levels are maintained along
its length by three reservoirs, the largest of which is Lake Gatun, visible at the right center
of the image. Built by the U.S. Army Corps of Engineers between 1904 and 1914, the canal extends
for approximately 50 miles, and is widely considered to be one of the world's great engineering
achievements. This shaded relief perspective view was generated using topographic data from the
Shuttle Radar Topography Mission (SRTM). A computer-generated artificial light source illuminates
the elevation data to produce a pattern of light and shadows. Slopes facing the light appear
bright, while those facing away are shaded. On flatter surfaces, the pattern of light and shadows
can reveal subtle features in the terrain. Colors show the elevation as measured by SRTM, and range
from green at the lowest elevations to white at the highest elevations.
Location: 9.0 degrees North latitude, 79.8 degrees West longitude
Orientation: looking West
Original Data Resolution: SRTM 30 meters (99 feet)
Date Acquired: February 2000 (SRTM)
