A spatial index backed by geohashing and Trie (prefix tree) maps. Geometries are encoded as geohashes and stored in a prefix tree, and reverse lookups are performing by encoding the queried geometry and using the prefix tree as an inverted lookup index. The index size can be tuned with the precision parameter. The geohasher and prefix tree map providers can be injected by implementing the IGeohasher and/or IGeohashTrieMap interfaces. This package provides common spatial operations that can be used on an index, such as STContains(), STIntersects(), and so on. A complete overview is available at the project site.
