spatial indexingA means of accelerating coverage drawing, spatial selection, and feature identification by generating feature-based indexes for one or more feature classes of a coverage.

Spatial indexing, then involves associating the data with different cells and vice versa. During queries, one first finds the cells occupied by the query region, and then finds all the data associated with these resulting cells.
A spatial indexing system. Operators, functions, and procedures for performing area-of-interest queries, spatial join queries, and other spatial analysis operations. Functions and procedures for utility and tuning operations.
To ensure the fast retrieval of features in a selected region some type of spatial indexing (e.g. quadtree) should be applied.
In the complete data workflow for the computation of a quality indicator map, the error propagation is carried out using the navigation data an their accuracy estimates. After the RT point cloud generation, we build up a k-d tree for spatial indexing.
Special data structure used in a database to speed searching for records in tables or spatial features in geographic data sets. ArcInfo supports both spatial and attribute indexes. See also item indexing, cross-tile indexing and spatial indexing.
