If you are using ArcGIS, you can do this a couple of ways. The simplest
would be to start an edit session. Select all the polygons you wish to
consolidate into a single layer. Paste them in to a single layer. Lastly
Save and stop editing. You can also use the Simple Data Loader in
ArcCatalog to do this as well.

Subject: shrug-l: Combining Shapefiles

This is probably a no-brainer for most of you but . . . 

I created 72 polygon shapefiles for all the Superfund sites in Florida.
Rather than deal with 72 layers, I would like to create a new layer with
each of the 72 shapefiles as a record in the final attribute table.
Then I can join the resulting table with a Superfund database to "fill
in" the remaining important information.  Since most of the 72 layers
were created by dissolving multiple parcels into the site polygon, they
all have the same basic attributes table now, just the FID, Shape and ID
fields, all blank.  It would probably be a good idea to add a field for
the site name or ID number, but I don't know if this is best
accomplished before or after creating the combined table.  I will also
probably add perimeter, area and centroid data to the tables after
combining them all (that I know how to do).
