 dbb:  isnt there a case to be made to take a very high number of vertices POLY, and simply provide a call to break it into some number of polys with max N vertices ?  Arc* definitely does this with a simple dialog box, and its a common user problem I think
 
-strk:  that too. can still be done using segment-splitting as the number of added points would likely not affect the overall reduction (I've been using that) BUT, segment-splitting would introduce spatial drift so that putting the "tiles" back together they wouldn't necessarily match
+strk:  that too. can still be done using segment-splitting as the number of added points would likely not affect the overall reduction (I've been using that) BUT, segment-splitting would introduce spatial drift so that putting the "tiles" back together they wouldn't necessarily match. of course you can't avoid that when you really want a gridded output
 
+dbb: hmm but thats at the level of the precision model. There are lots of problems at that level
+
+pramsey: a set-returning function that turns a big polygon into a set of tiles covering the same area
+
+dbb: isnt splitting using existing vertices straightforward?  "give me back POLY that has at most N vertices"
+
+pramsey: not if you're trying to generate a set of things that cover the same area. that strikes me as being quite hard. it's easy to break a line into smaller lines that way
+
+dbb: because of problems at the precision model level ?  Arc* has it somehow
+
+pramsey:  and what kind of shapes do the resulting outputs have? rectangular? pieces of pie? what?
+
+dbb:  they are N vertice polys.. you say "Take this monster 100,000 vertice poly, with one outer ring I suppose.. and break it into M polys with max N vertices each"  if you specify N then M is calculated
+
+strk:  they are probably clusters of triangles.. unioned
+
+pramsey:  could be strk, triangulate and then rebuild
