I have a public web interface that is inteneded to allow users to extract shapefile data from Oracle SDE via GP key in. I have published parameters and created the interface but I dont know what transformers to use in the workbench to allow the GP clipping. Something about attribute filer I suspect.

Hi,
I have difficulties understanding your question. Could you please tell what "GP clipping" means in this context?

I want users to be able to key in Lat/Longs and extract data by that bounding box. GP extract probably makes more sense.
Hi,
Since you data resides in a database you can make use of the min/max XY + clip to search envelop parameters, usually found under parameters>advanced.
This way the users can enter min/max XY coords for the writer to clip.
Hope this helps,
Itay
Hi,
I'm not sure what the "GP" means. Geo Processing?
If you need to filter features using a geometry specified by user, consider using the SpatialFilter or Clipper. Or else, the BoundsExtractor can be used to get the coordinates of corners of a bounding box surrounding a geometry, the BoundingBoxReplacer or BoundingBoxAccumulator can be used to create a bounding box area.
You have a choice depending on what you want to do.

correction :
This way the users can enter min/max XY coords for the READER to clip.
GP in this case is Global Position, Lat/Long Clipping. Sorry I wasn't more specific.
Hi,
you could accomplish this with a Creator followed by a couple of 2DPointAdders and a LineCloser based on the Lat/Lon published parameters to build the clipping polygon, which you then pass on the the Clipper.
