The Space Oblique Mercator for Landsat projection is a pre-computed
form of the **Space
Oblique Mercator** projection that allows specification of the
projection by citing a **Landsat Orbit
Number** and **Orbit Path Number**.

A modified cylindrical projection with the map surface defined by a satellite orbit. Basically conformal, especially in region of satellite scanning.

Continuously true to scale along ground track of satellite.

Near-zero distortion along ground track of satellite.

Used for mapping images from Landsat series satellites. May be used for any satellite orbiting the Earth in a circular or elliptical orbit and at any inclination.

Developed in 1973 - 1979 by Alden P. Colvocoresses, **John Parr Snyder**
and John L. Junkins. Colvocoresses was the first to realize that such
a projection was needed and mathematically feasible, and in 1974 defined
it geometrically. Snyder created the definitive formulas for the projection
in 1977 - 1979, while less complete formulas were also created by Junkins
in 1977. Snyder provided a complete derivation for orbits of any ellipticity
in 1981.

Use the **Space
Oblique Mercator** projection for access to all parameters.
