%X A vague spatial data warehouse allows multidimensional queries with spatial predicates to support the analysis of business scores related to vague spatial data, addressing real world phenomena characterized by inexact locations or indeterminate boundaries. However, vague spatial data are usually represented and stored as multiple geometries and impair the query processing performance. In this paper, we introduce an index called VSB-index to improve the query processing performance in vague spatial data warehouses, focusing on range queries and vague regions. We also conduct an experimental evaluation demonstrating that our VSB-index provided remarkable performance gains up to 97% over existing solutions.
