Map Projection Parameters
The following elements comprise the Map Projection Parameters section:
	Standard Parallel mandatory line of constant latitude at which the surface of the Earth and the plane or developable surface intersect. Note: can be entered once or twice as applicable
	Longitude of Central Meridian, mandatory the line of longitude at the center of a map projection generally used as the basis for constructing the projection.
	Latitude of Projection Origin, mandatory latitude chosen as the origin of rectangular coordinates for a map projection.
	False Easting, mandatory the value added to all "x" values in the rectangular coordinates for a map projection. This value frequently is assigned to eliminate negative numbers. Expressed in the unit of measure identified in Planar Coordinate Units.
	False Northing, mandatory the value added to all "y" values in the rectangular coordinates for a map projection. This value frequently is assigned to eliminate negative numbers. Expressed in the unit of measure identified in Planar Coordinate Units.
	Scale Factor at Equator, mandatory a multiplier for reducing a distance obtained from a map by computation or scaling to the actual distance along the equator.
	Height of Perspective Point Above Surface, mandatory height of viewpoint above the Earth, expressed in meters.
	Longitude of Projection Center, mandatory longitude of the point of projection for azimuthal projections.
	Scale Factor at Center Line, mandatory a multiplier for reducing a distance obtained from a map by computation or scaling to the actual distance along the center line.
	Oblique Line Azimuth, mandatory method used to describe the line along which an oblique mercator map projection is centered using the map projection origin and an azimuth.
	Oblique Line Point, mandatory method used to describe the line along which an oblique mercator map projection is centered using two points near the limits of the mapped region that define the center line.
	Straight Vertical Longitude from Pole, mandatory longitude to be oriented straight up from the North or South Pole.
	Scale Factor at Projection Origin, mandatory a multiplier for reducing a distance obtained from a map by computation or scaling to the actual distance at the projection origin.
	Landsat Number, mandatory number of the Landsat satellite. (Note: This data element exists solely to provide a parameter needed to define the space oblique mercator projection. It is not used to identify data originating from a remote sensing vehicle.)
	Path Number, mandatory number of the orbit of the Landsat satellite. (Note: This data element exists solely to provide a parameter needed to define the space oblique mercator projection. It is not used to identify data originating from a remote sensing vehicle.)
	Scale Factor at Central Meridian, mandatory a multiplier for reducing a distance obtained from a map by computation or scaling to the actual distance along the central meridian.
	Other Projection's Definition, mandatory a description of a projection, not defined elsewhere in the standard, that was used for the data set. The information provided shall include the name of the projection, names of parameters and values used for the data set, and the citation of the specification for the algorithms that describe the mathematical relationship between Earth and plane or developable surface for the projection.
