If zero, a zone code must be specified. Lat/Z Latitude of any point in the UTM zone or zero. If zero, a zone code must be specified. SMajor Semi-major axis of ellipsoid. If zero, Clarke 1866 in meters is assumed. SMinor Eccentricity squared of the ellipsoid if less than zero, if zero, a spherical form is assumed, or if greater than zero, the semi-minor axis of ellipsoid. 2 Sphere Radius of reference sphere. If zero, 6370997 meters is used.

A portion of Landsat rows 1 and 2 may also be seen as parts of rows 246 or 247. To place these locations at rows 246 or 247, set the end of path flag (parameter 11) to 1--end of path. This flag defaults to zero. When Landsat-1,2,3 orbits are being used, use the following values for the specified parameters: Parameter 4 099005031.2 Parameter 5 128.87 degrees - (360/251 * path number) in packed DMS format Parameter 9 103.2669323 Parameter 10 0.5201613 When Landsat-4,5 orbits are being used, use the following values for the specified parameters: Parameter 4 098012000.0 Parameter 5 129.30 degrees - (360/233 * path number) in packed DMS format Parameter 9 98.884119 Parameter 10 0.5201613 4
