vector data

[Stephen Lime]

Yes. Drawing is essentially just extra work after doing a spatial query. So queries
give you access to the raw shapes. You could optionally clip and convert them
to image coordinates. Note this level of access would have to involve MapScript.
Currently, MapScript supports shapefile output but with access to the raw vector
data just about anything goes. We are currently working to add GML output as
well.

Clipping uses an algorithm suitable for scanline conversion (i.e. drawing) and is
done just before a shape is drawn.

just new to the list and not running mapserver yet, THIS is one of the
most inmportant questions to be answered.

i would ask more precisely: is there any output of the server imaginable
that takes place BEFORE rastering and that could be used instead of the
raster? or the other way round: does the clipping take place before or
after teh merging of layers inside mapserver?

thanks for any hints,

andré
