Hamish,

   Something here is not working properly; I'll probably need to re-import
the data for the lakes map and start over. For some reason the one lake
(actually, reservoir) appears to be a line rather than a polygon boundary.
When I convert the vector map to raster it does not appar on the output.

   I tried converting a copy of that map from boundary to face but that made
no difference; didn't try line to boundary because it's only the one lake on
the map that displays differently and doesn't convert to a raster.

Regards,
