Таблица SPATIAL_REF_SYS содержит числовые ID и текстовые описания систем координат, используемых в пространственной базе данных.

Each spatial instance has a spatial reference identifier (SRID). The SRID corresponds to a spatial reference system based on the specific ellipsoid used for

A spatial reference system (SRS) or coordinate reference system (CRS) is a framework used to precisely measure locations on the surface of the Earth as coordinates. It is thus the application of the abstract mathematics of coordinate systems and analytic geometry to geographic space.

A coordinate system (also called a spatial reference system) is a means of assigning coordinates to a location and establishing relationships between sets of such coordinates. It enables the interpretation of a set of coordinates as a representation of a position in a real world space.

SPICE system kernels and routines refer to ephemeris objects, reference frames, and instruments by integer codes, usually referred as the ID. The reference frame ID-name mappings routines constitute a subsystem separate from the body ID-name mapping routines. Please refer to the Frames Required...
