Dear list,
maybe this is a simple question, but I need a little help.
***************************************
My Questions:
what's the way to sort polylines clockwise who "come up to a circle" ?
********************
The data:
Imagine you have a table with polylines.
By selection you can get all polylines reprensenting one community boundary.
The selected polylines "come up to a circle", there are no gaps. // I don' t know
if this is the correct description
*****************
My problem:
the polylines are not sorted:
that means neither Rowids nor Start and end- nodes lead to the information that for
example Polyline 1
is clockwise connected to Polyline 8. and so on.
*****************
My wish:
I like to sort the polylines for example in an array,
that means I like to start with the polyline with the maximum Y coordinate and order
the
following polylines clockwise.
This duty should be integrated into a mapbasic script.
Any suggestions would be helpful.
Thanks in Advance
Hendrik Possberg
