MI MB: How do I convert PLINE into LINE?

[m . e . smith]

Hi, We collect data using GPS, so a single line (e.g. a vineyard row) is composed of (for example) 10 nodes at the start of the line and 10 nodes at the end of the line.  (every second measurement we make is converted into a node).  Now, I want to average the 10 nodes at the start and end of the line & then convert it from a polyline into a line.  Any suggestions as to how to go about this?  I don't want to generate a new line in exactly the same position as I'll then lose all the attribute data that was also collected with that line.    ********************************* Michelle Smith Technical Manager Frontier Mapping Pty Ltd ******************************************
