The Boost.Geometry Index is intetended to gather containers (spatial indexes)
|
|
used for speeding spatial queries up. It is a part of the <a href="http://www.boost.org/libs/geometry/doc/html/index.html" target="_top">Boost.Geometry</a>
|
|
library. In general, spatial indexes stores geometric objects' representations
|
|
and allows searching for objects occupying some space or close to some point
|
|
in space.
|
|
</p>
|
|
<p>
|
|
Currently, only one spatial index is implemented - R-tree.
