Importing ASCII multiline features

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 Example .

To import multiline features from an ASCII file, choose the New Theme from ASCII file menu choice in the View menu in the view window.
