A Kind Index Structure based on VGI information Combined Query

摘要

The paper proposes a kind of data index structure - the hiberarchy index tree to implement joint inquiry, this structure can expand the search range and has the ability to quickly query. The experiments confirmed that the proposed the hiberarchy index tree can create spatial index, implement a direct link between MBR based index and non-spatial feature, and can quickly query multiple data sources. The experiment shows that the hiberarchy index tree is much validated and something useful is obtained.
