Hello,
Thanks to Keith Campbell, Trey Pattillo, Martin Roundill,
and Jim Spriggs for their input.
Basically, there were two suggestions:
1- The "Convert to polylines" option in the "Objects"
menu.
2- Use the mapbasic window to run these commands: a) type
"update selection set object = conterttopline(object)" after selecting all the lines; then
b) update the table by typing "update mytable set
object = conterttopline(object)".
I had already used the
first alternative, but got these odd-shaped polygons when converting to
regions; that was the reason I thought I was doing something wrong until I found
the real problem. The data contained very short lines and polylines
(5 meters or less) representing piers, which in some cases were part of a
shoreline, in others, they protruded out acting as "dangles". Once I
took the latter out (which was not too easy), I selected all the line segments
(Str$(obj) = "line"), converted to polylines, and then to
regions.
Thank you
again.
Regards,
Miguel Iturralde
