Walter,
Setup the layer as a POINT layer and construct a SQL query that extracts
the first point of the line segment. You might want to create a view to
simplify the SQL in the mapfile or to create an index on the points.

MapServer itself cannot selectively display just one point from a
feature. Perhaps there is a Oracle function to do the extraction on
the database side? PostGIS users might have an idea that could be
translated into Oracle.

Hi Folks!
We have a rather tricky problem and maybe someone out there knows a
solution. We have a layer of rivers, divided in 500m Segments,
stored in an Oracle Spatial DB. Each segment is a simple line with
a starting point and an end point, but they shall not be displayed
a slines, but rather as points. What we want is simnply to
represent every segment by its starting point only. Is that
possible?
