Is there a way to quickly snap all edges within this shapefile together? It's a geologic map so there are lots of irregularly shaped polygons and it would be time consuming to re-create the entire layer. I'm using ArcView 9.3, but would consider using GRASS, QGIS, etc. if the capability is there.

"There is much beauty that we fail to see through our own eyes teeming with life forms that give us that perception of our reality. Leaves on the trees blowing gently in the wind, or scarily, the waves pounding through high surf, or lightly on a warm summer’s day; that opportunity to sit or swim in the water on a white beach. That comfort to shout, “The universal conscious do you hear me? I am alive, guide me dear logos towards the path of rightnesses.” Earned what has been kept, no longer to be absorbed into a life filled with cold damn winds and that stubborn fog clouding my vision with nothing but darkness."

There are two tools I know of for this problem provided in the ArcGIS toolbox. If you have them all depends on your license.
* Integrate (Data Management tools)
* Clean (Coverage tools - needs a ArcInfo Workstation license)
Using coverage tools ususally yields better results, as coverages know topology.
Hope it helps.

What happens if you don't display the boundaries, is there a lack of contrast between the polygons then? I am thinking that the sliver gaps/overlaps might not be so visible then.
If you are moving to illustrator later you can also play with the boundaries using live paint.
Hasdrubal - I think we are seeing a close-up, so the bg image (shaded relief?) might look ok/reasonable for the intended view.

I think the most limiting factor in solving this problem is going to be my Arcview licensing limits as there appear to be several tools to complete the task, and those tool names are what I was most interested in finding.
(Oh, and yes you are viewing lidar topography from a 1:60,000 scale map at ~1:20 super-zoomed-in, hence the 600 pt type below the polygon lines . )

I've realized that I'm not licensed for smooth line, smooth polygon, or create topology tools, which sucks. I'm going to see if ESRI help has a breakdown of all tools included with ArcView vs. ArcInfo somewhere.
Thanks again for your help!
