Hi I have a featureclass that contains many polygons many of which have gaps and splinters between them.  My concern is that some of the polygons are very small and narrow, some smaller than a few of the gaps. How do I remove the gaps and splinters without collapsing the polygons.

Thanks Jane

on a copy! of the file, try Integrate,

otherwise you are looking at topology....

You could also try doing a select by attribute to select the polygons, which presumably, have a small area, and buffer those slightly, prior to performing the above.  If the area method is selecting other polygons which are fine... skip the idea

You could select polygons which are very small and narrow by using select by attribute based on its Area. After selection verify them if they are satisfying your criteria.

Finally use Eliminate GP Tool from Data management->Generalization to  merging them with neighboring polygons.

For gaps look for topology as suggested by Mr. Dan Patterson.
