Does anyone know where I might obtain GIS shapefiles
concerning hydrology (water bodies, shorelines, etc.) and
cultural features, specifically roads, for the Mississippi
River Delta region? I am looking for shapes files, which
I can import into Map Publisher for Adobe Illustrator CS
(Macintosh G4) to use in maps, which I am preparing
for some reports.

I have tried the Louisiana GIS CD (http://lagic.lsu.edu/giscd/)
and found that the water bodies shapefile works quite well.
However, apparently because it was created from a raster
image, the land-water inferface shapefile, which contains the
shoreline linework, is noticably jagged for parish-scale maps.
The GIS CD's shapfiles for roads are often noticably incomplete.

If anyone knows of any alternative sets of shapefiles, which
can I can use in to make map figures, for the Mississippi River
Delta region, specifically Jefferson, Orleans, St. Bernard, and
Plaquemines parishes, I would be very interested in finding
out where I can acquire them.

Any assistance aanyone can give me will be greatfully
appreciated.

Best Regards,

Paul,

There's a set of links to GIS data resources here (look in the Interesting Links) areas that might have something useful for you. My initial thought was seamless.usgs.gov

You may also want to consider Avenza's "Map Data USA", a commercial product however, but guaranteed to be MAPublisher-compatible.

Look for some of the DLGs from the USGS should be able to find both 1:24k and 1:100k linework. if not for free from a commercial vendor like mapmart for fairly cheap.
