Stereo Pairs

An explanation of stereo pairs and their use (PDF)

Planned stereo pairs have suitable stereo convergence angles and illumination by design. In addition to planned stereo pairs, the Pairendipity software can identify overlapping HiRISE images that are serendipitously suitable for stereo processing and find stereo pairs within the CTX dataset.

Planned HiRISE stereo pairs are listed in the “Stereo Pair List (CSV)” link below. Since this list is based on produced stereo anaglyphs it also contains a few serendipitous pairs that underwent special processing. Most serendipitous HiRISE stereo pairs are listed in the “Pairendipity Stereo” link, while CTX stereo pairs are listed in “Pairendipity CTX Stereo”.

Images taken close together in time minimize illumination and frost differences and are especially useful (see the Delta-Days column in the Pairendipity files or difference the orbit numbers in the image IDs in the Stereo Pair List file). Stereo pairs with both images planned within the same 14-day (168-orbit) operations cycle are known as SPORCs.
