          Field Definition:  The datum associated with the image.

Valid Code: WGS 84 = Worldgeodetic System 1984 Ellipsoid

          Field Definition:  The ellipsoid associated with the image.

Valid Code: WGS 84 = Worldgeodetic System 1984 Entity ID

          Field Definition:  This field uniquely identifies the individual landsat scene.

Example: L71168016_01620010717   Valid Format: CCSPPPRRR_EEEYYYYMMDD   CC = Landsat 7 Spacecraft S = Satellite 1 PPP = WRS Path number RRR = Starting WRS Row Number _ = Separator between staring and ending row EEE = Ending WRS Row Number YYYY = Year of acquisition MM = Month of acquisition DD = Day of acquisition File Size

          Field Definition:  The size of all files associated with the scene, in bytes.

          Field Definition:  The map projection used to create the image.

Values: Valid code = UTM Orientation

          Field Definition:  The orientation of the image.

Values: Valid code = NOM (Nominal) Resampling Option

          Field Definition:  The resampling applied to the scene.

Valid Code: MTF = Modulation Transfer Function Satellite

          Field Definition:  The satellite which acquired the data.

Values: Valid Code = Landsat 7 Sun Azimuth

           Field Definition:  The Sun azimuth angle at the "true" WRS scene center. Azimuth is the angle of horizonal deviation, measured clockwise from the north.

Values: -180.0000000 through +180.0000000 degrees (with 7-digit precision)   NOTE: A positive value Sun Elevation

          Field Definition:  The Sun elevation angle at the "true" WRS scene center. Elevation is the angle of vertical deviation from the tangent to the earth's surface (at scene center point) to the line between the sun's center and the scene center point. NOTE: The solar zenith angle will be 90 degrees minus the solar elevation angle.
