JANUARY 24--Space Imaging (Denver, CO) is now offering 1-m resolution, stereo imagery products from its IKONOS satellite. Stereo products consist of two IKONOS satellite images of the same location on Earth, taken from two different perspectives during one orbital pass. The pair of images is collected in-track, or on the same ground path just moments apart, to maintain the tonal consistency between each image, enabling better interpretability. One of the two images is taken at a high elevation angle of greater than 72°, which can be used to make a highly accurate orthorectified image.
The primary advantage of stereo imagery is the ability to extract cultural and geographic features, such as buildings, roads, and elevation contours, in three dimensions. Stereo imagery is especially important for global markets where accurate elevation data are not readily available. For example, airport officials can use stereo imagery for navigation and simulation.
