- Longitude
- For a Planetocentric, body-fixed, rotating coordinate system, longitude is defined as: The angle increasing eastward between the prime meridian and the vector from the coordinate system origin to the point of interest, projected into the equatorial plane. This is a right-handed coordinate system.
For a Planetographic, body-fixed, rotating coordinate system, longitude is defined as: The angle between the prime meridian and the vector from the coordinate system origin to the point of interest, projected into the equatorial plane.
Planetographic longitudes are defined to increase with time for a distant observer. Thus, they increase to the west for prograde rotators, and to the east for retrograde rotators. For the Earth, Moon and Sun, PDS also supports the traditional use of the range (-180,180). - Examples (use TAP/PARAM syntax)
- 127.3/ means L ≥ 127,3
- 120/123 means 120 ≤ L ≤ 123
- /23 means L ≤ 23
Help
- Latitude
- For a Planetocentric, body-fixed, rotating coordinate system, latitude is defined as: The angle between the equatorial plane and a vector connecting the point of interest and the origin of the planetocentric coordinate system. Positive in the hemisphere north of the equator (i.e., hemisphere to the north of the solar system invariant plane) and negative in the southern hemisphere.
For a Planetographic, body-fixed, rotating coordinate system, latitude is defined as: The angle between the equatorial plane and a vector through the point of interest that is normal to a biaxial ellipsoid reference surface. Positive in the hemisphere north of the equator (i.e., hemisphere to the north of the solar system invariant plane) and negative in the southern hemisphere. - Examples
- 127.3/ means L ≥ 127,3
- 120/123 means 120 ≤ L ≤ 123
- /23 means L ≤ 23
