Subject:      Contour lines
Content-type: text/plain; charset=us-ascii

Dear colleagues,

I've got three dimensional data with coordinates x and y (on a regular
grid) and an outcome on the third axis. Now I can run Proc Contour to
see the countour lines but neither an output dataset can be, nor an ods
table with the contour lines is generated, only plotted.

In order to write data as a "region" object in MIF (MapInfo Interchange
Format) format, not only the coordinates of the level specific countour
lines are needed, furter it is important to know its right order per
region. That is not just to have the boundary points somehow, but in the
order you pass them when you follow the lines with a pen.
To make it short: I am looking for a way to specify the ordered boundary
points of the contour lines.

Many thanks for help.
Armin
