Hi,
We are using FME 2006 GB Build 2651.
I am cliping a large raster image (Geotif) into tiles using a
shapefile of 1:20 000 mapsheet boundaries to create a tile for each
mapsheet using the clipper. My shapefile is the clipper and the
raster is the clippee. The shapefile has (in this case) about 50
individual shapes for the mapsheets, so I end up with about 50 tiles
(one for each mapsheet) This works great.
What I would like to do is have the output tiles written with names
according to the mapsheet that was used to clip it out from the
shapefile. The name of the mapsheet is stored in the shapefile as an
attribute (MAP_SHEET).
So for example, the for the area in the raster image that is clipped
by mapsheet 092K049 it would be output as a tile called 092K049.TIF
I have tried setting merge attributes: Yes and then using the merged
name of the field (clipper_MAP_SHEET) as the feature type name in my
output file but I think because this is a raster that is not working.
I also tried exposing the attribute geotiff_raster_filename in the
output file and routing the clipper_MAP_SHEET value directly to it,
but that did not work either.
I looked at the tiler but that does not have this option either.
I can rename them manually after the clipping is done but thought
there might be an easier way.
Thanks for any suggestions.
Chris
