A Multiline feature is characterised by a set of discontinuous lines, where
the location and shape of each line is specified by a similar number of point
sets, and sharing the same descriptive attributes. The ASCII file may have zero or
two header lines. The first headerline must include the ID column name and
attribute field names, while the second headerline include the co-ordinate column
names. The next lines define the multiline features, where each feature is
defined with an attribute line, one co-ordinate line for each point defining the
multiline feature, a number of 'newpart' lines, and an 'end-of-feature' line. The
attribute line includes the feature ID and other attribute values for the
multiline feature. The 'newpart' line just includes the word NEW in the beginning
of the line. After reading this line, INSROP GIS interprets the next line as the
first point co-ordinate in the next line part of the multiline feature. The
'end-of-feature' line just includes the word END in the beginning of the line.
After reading this line, INSROP GIS interprets the next line as the attribute
line of the next multiline feature. See
