Detailed Description

This class is a base class for the ITS geometry version 11. It contains common/standard functions used in many places in defining the ITS geometry, version 11. Large posions of the ITS geometry, version 11, should be derived from this class so as to make maximum use of these common functions. This class also defines the proper conversion values such, to cm and degrees, such that the most useful units, those used in the Engineering drawings, can be used.
