/* * REGISTERABLE ENUM: SRM_Ellipsoid_Of_Revolution * * This data type specifies the list of * 1) reference ellipsoids of revolution and 2) spheres * used in defining an Object Reference Model (ORM) within the * Spatial Reference Model (SRM). * * This list is taken from Tables C.2 and C.3 of the SRM, WD5. * See the SRM for details on how the selection of a horizontal * datum affects an ORM. See Table C.3 for the definitions of the * semi-major axis and inverse flattening values for each of the * listed ellipsoids of revolution, and table C.2 for the radii * of the listed spheres. */ typedef SRM_Short_Integer SRM_Ellipsoid_Of_Revolution;
