Thanks Sebastian. I had heard of that, but I never used it, based on my
expeience with ArcView and ArcGIS; crashes and funny maps.

How would you produce that simplified version is none is available

A very conveniant way of simplifying big shapefiles is dumping them in
PostGis/Postgresql using shape2pgsql, then creating a new geometry
column and fill the data with "UPDATE <table> SET <newcolumn> =
simplify(the_geom,0.01)
where the 0.01 is the tolerance factor, this number works well for me in
longlat units. Then you can dump the table back to a shapefile using
pgsql2shp.
This way, simplifying huge shapefiles is really fast and stable, while
in ArcGIS it's taking hours, and then just crashes.
