The MinimalBoundingBox finds the smallest rectangle that encloses a feature or set of features and has the same orientation as the input feature. This uses the Rotating Calipers method from http://cgm.cs.mcgill.ca/~orm/rotcal.frame.html It assumes that a convex feature as input, so a ConvexHullAccumulator or ConvexHullReplacer is needed first.

This has nearly become obsolete with the new "Oriented Bounding Box" option in the BoundingBoxReplacer, FME 2010, ~ build 6048, April 2009. The BoundingBoxReplacer can potentially find a smaller box which has a different azimuth than the input feature, which might not be ideal for building footprints.
