Hi,

I see that a fourth node splitting algorithm for bulk loading is documented in the Introduction to spatial indexes but not listed elsewhere (such as Creation and Modification).
Is it hiding in the library somewhere or is the introduction just a tantalizing sneak preview?

The packing algorithm is used if the R-tree is created with a constructor taking a range e.g. as a pair of Iterators:

http://www.boost.org/doc/libs/1_56_0/libs/geometry/doc/html/geometry/reference/spatial_indexes/boost__geometry__index__rtree/rtree_iterator__iterator_.html

Yes, maybe it should be explicitly stated in the "Creation..." section.

Ah, fantastic. Hah, turns out I was already using that constructor.

So what should I write as the second required template parameter, which is usually linear<N>, quadratic<N>, etc? Is it just ignored in the packing case? If so, that's a bit confusing.

Thanks, cheers.
