[Mapserver-users] buffering lines and polygons

Depends what you mean by buffering. True buffering, that is, creating
new features is not supported. However, buffered queries are supported.
The development version now features code that respects layer TOLERANCE
values for queries by feature or shape. So, you can do things like find
all streams within 5 miles of a lake. At the moment only points and
polygon-based shapes can do this (points have always respected
TOLERANCE). Lines can easily be supported (they are via MapScript) with
a few edits to mapquery.c.

this has been asked before, but I don't know the definitive answer.

What's the ETA on the capability to buffer lines and polys, if at all?

If someone has implemented this already on their own, any directions
will be appreciated.

Many tia,

Puneet.
