virtual

Derived classes implement their particular tiepoint matching algorithms for the requested tile.

It is not clear what the output tile needs to be, since the product of this filter is the list of tiepoints (available through the getTiePoints() method). Recommend simply passing through the corresponding REF image tile.

Implements ATP::AtpTileSource.
