Geonic vector format

Geonic coordinate files. Comment line after the point is stored to point as an attribute.

Uses the same coding system as 3D-Win. However, field width is limited to eight characters. Lines are formed according field T2: 0 or empty means single point and new line starts when the number changes.

If two lines with same line number are separated by a single point, they are read as two separate lines (Xroad).
Haso-format is used by Finnish Maritime Administration.

Format header file can contain macros and file attributes. Because the line coding is based on the line numbers, letter X is added to the field T2 of the latter of adjacent lines with same number. Also, T2 is cleared from single points.

Minimum line

Lines numbers smaller than this value are handled as single points.
