Can anybody help with this question? I seem to recall seeing a similar question here recently but can't recall it exactly.

I have X, Y, Z co-ordinates of nodes in a string file, representing nodes along contour lines on a map. Each group of nodes in the file, representing each of the contours, is separated by zero entries in the string file, so the entire file looks a bit like this:

X,Y,Z
5,3,24
4,4,24
3,5,24
0,0,0
6,4,23
5,5,23
4,4,23
0,0,0
etc.
etc.

Is there a simple way to get Mapinfo to draw each of the contour lines, and assign a level for each contour?

Thanks in anticipation.

For MapInfo, see the MapInfo discussion list at: http://www.mapinfo-l.com

MapPoint will do it if the X/Y are in latitude longitude (WGS 84 or NAD 83). The Z could be a range with integers 1-8 (you could massage your data to make it appear like this) and then you could have differently colored pushpins representing the Z portion.

You could also draw contour lines using the AddLine method.
