The selenographic coordinate system is used to refer to locations on the surface of Earth's moon. Any position on the lunar surface can be referenced by specifying two numerical values, which are comparable to the latitude and longitude of Earth. The longitude gives the position east or west of the Moon's prime meridian, which is the line passing from the lunar north pole through the … Web2.

WebCoordinate systems used in near-Earth space physics have been well covered by the works of Russell (1971) and Hapgood (1992). But there has been a lack of publicly available documentation on coordinate systems used in heliospheric space missions and in many cases the information does not seem comprehensive enough for reference purposes1. WebCoordinate systems for solar image data. Thompson, W. T. A set of formal systems for describing the coordinates of solar image data is proposed. These systems build on current practice in applying coordinates to solar image data. Both heliographic and heliocentric coordinates are discussed.
