Just in time for the U.S. National Park Service’s Centennial celebration on Aug. 25, the Multiangle Imaging SpectroRadiometer (MISR) instrument aboard NASA’s Terra satellite is releasing four new anaglyphs that showcase 33 of our nation’s national parks, monuments, historical sites and recreation areas in glorious 3-D.
MISR views Earth with nine cameras pointed at different angles, giving it the unique capability to produce anaglyphs — stereoscopic images that allow the viewer to experience the landscape in three dimensions. The anaglyphs were made by combining data from MISR’s vertical-viewing and 46-degree forward-pointing camera.
If you’d like to experience the images with the 3-D effect, you will need red-blue glasses; make sure you place the red lens over your left eye. The images have been rotated so that north is to the left in order to enable 3-D viewing because the Terra satellite flies from north to south. All of the images are 235 miles (378 kilometers) wide from west to east.
