[Benchmarking] Sample Barcelona Vector Dataset

[Jeff McKenna]

Thanks Marco, I have applied your scale visibility to my layers, and 
uploaded their SLD documents.  I also added reference to these scales in 
the wiki: 
http://wiki.osgeo.org/wiki/Benchmarking_2010/How_to_get_some_sample_data#Vector_data_issues

Other notes:

- As Andrea pointed out, MapServer seems to have a problem with 
generating an SLD with a LABEL (it doesn't include the 
<ogc:PropertyName> tag).  A ticket was already filed: 
http://trac.osgeo.org/mapserver/ticket/3023

- if we wish to use the Contour layer for labels, the field that we 
would use is COTA_0201; the problem is that that field has a precision 
of 15, meaning existing values are similar to "300.000000000000000". 
MapServer doesn't have a way (yet) to trim these values (there are ways 
around this but extremely slow).  Normally I would pre-process the data 
file to make it an integer field.

Are we too late to re-process the contours.shp file and change the field 
type??
