dD Spatial Searching
Reference Manual

Hans Tangelder and Andreas Fabri

This package provides data structures and algorithms for exact and approximate distance browsing, supporting

• both nearest and furthest neighbor searching,

• both exact and approximate searching,

• (approximate) range searching,

• (approximate) k-nearest and k-furthest neighbor searching,

• (approximate) incremental nearest and incremental furthest neighbor searching,

• query items representing points and spatial objects.

The spatial searching package consists of the following concepts and classes that are described in the reference pages.
