This is an ortho-image of Hebes Chasma, a trough in the Grand Canyon of Mars. The image is overlaid with elevation data from an HRSC-derived high-resolution digital terrain model (DTM).
In an ortho-image, the projecting rays are perpendicular to the plane of projection. This corrects any deformations
introduced by an imaging camera. Such an image can be fitted directly on to a map.
Hebes Chasma is located at approximately 1° south and 282° east. Image data was obtained on 16 September 2005 with a ground resolution of approximately 15 m/pixel.
