Description:

Spatial indexing libraries.
The purpose of this library is to provide:
- An extensible framework that will support robust spatial indexing methods.
- Support for sophisticated spatial queries. Range, point location, nearest
neighbor and k-nearest neighbor as well as parametric queries (defined by
spatial constraints) should be easy to deploy and run.
- Easy to use interfaces for inserting, deleting and updating information.
- Wide variety of customization capabilities. Basic index and storage
characteristics like the page size, node capacity, minimum fan-out,
splitting algorithm, etc. should be easy to customize.
- Index persistence. Internal memory and external memory structures should be
supported. Clustered and non-clustered indices should be easy to be
persisted.
