Standard parallel standard parallel: A parallel of latitude used as a control line in the computation of a map projection, and which is therefore, true to scale. Some map projections have no defined standard parallel, others have one, while others have two. (iii) Standard parallel A standard parallel is a line of latitude that has true scale.

In some projections, you will also see parameters called the latitude of center and the central parallel. These two terms seem to have the same meaning. Like the latitude of origin, they define the starting point of the y-coordinates; unlike it, they are nearly always the middle parallel of the projection.

Target systems, such as a desktop computer or a printer, require only a standard parallel port to benefit from the TransProcessor's speed.

A standard parallel may or may not coincide with the latitude of origin. Top: The Cylindrical Equal Area projection has a single standard parallel. By default, it is the equator, but you can change it. Bottom: The Behrmann projection is the same projection, but with two standard parallels at 30° N and 30° S. These standard parallels define the projection and cannot be changed.

Standard Parallel Port (SPP) Definition - What does Standard Parallel Port (SPP) mean? A standard parallel port (SPP) is a port for connecting various relatively high bandwidth peripherals, most commonly printers, to a PC. Later versions of the SPP allow duplex communication. They use the DB-25 connector. The original SPP, by Centronics, was introduced in 1970 and soon became the de facto industry standard.

Standard parallel. standard parallel: A parallel of latitude used as a control line in the computation of a map projection, and which is therefore, true to scale. Some map projections have no defined standard parallel, others have one, while others have two. A standard parallel is a line of latitude that has true scale. Not all projections have standard parallels, but many common ones do. Conic projections often have two.

All they do is define where the map's x,y units will originate. When data is unprojected, it doesn't have x,y units. Locations are measured in latitude and longitude, as you know from the previous module. But when you set a projection and flatten everything out, you also start using a new way to measure location.

A standard parallel is a line of latitude that has true scale. Not all projections have standard parallels, but many common ones do. Conic projections often have two. In a few projections, like the Sinusoidal and the Polyconic, every line of latitude has true scale and is therefore a standard parallel.
