Line format used by Sonera.
Coordinate systems are selected in project settings. Defaults are KKJ zone based on Y-coordinate and undefined height system. Last column comment is content of COMMENT-attribute.
Sonera coding uses four character codes and the code of the first point of line ends with character zero. Because 3D-Win does not allow different codes for line points, coding must be handled by one of the following ways:
1) Three character codes are used in surveying. Writing then adds automatically zero after codes of single points and first line points. Number one is added after all other line points. Reading strips last number automatically from all codes.
2) Four character codes are used in surveying. Writing replaces the last character of the first line point with zero. All other codes are left unmodified. Reading requires special setting SoneraFlag 1 full code, which leaves the code unmodified.
