During the geodesy campaign in May and June 1999 the wide-angle system of the Mars Global Surveyor Mars Orbiter Camera imaged the visible surface of Mars from latitudes 70¿S to 90¿N. Over 90% of this portion of the planet was covered at two viewing angles to obtain side-looking stereo at a resolution of ~250 m/pixel and convergence angles of 21¿--27¿. Continuous radiometric spacecraft tracking during this period provided precise orbit determination of spacecraft location. This data set will become the basis of a new image mosaic of Mars, with the potential to exceed the geodetic precision and image quality of those presently available. ¿ 2001 American Geophysical Union
