Eliminates polygons by merging them with neighboring polygons that have the largest area or the longest shared border.
Eliminate is often used to remove small sliver polygons that are the result of overlay operations, such as those performed by Intersect and Union tools.
The Dissolve Tool unifies adjacent boundaries based on common attribute values.
Only if neighbor polygons have the same dissolving attribute, then it melts the boundary into one.
Dissolving is mainly for generalization and always simplifies boundaries from
