This tool can be used to remove the interior, or shared, boundaries within a vector polygon coverage. You can either dissolve all interior boundaries or dissolve those boundaries along polygons with the same value of a user-specified attribute within the vector's attribute table. It may be desirable to use the `VectorCleaning` tool to correct any topological errors resulting from the slight misalignment of nodes along shared boundaries in the vector coverage before performing the dissolve operation.
