  • In this work, we leverage Cloud computing technologies in scaling out data management in geographical databases. In particular, we tackle the issue of data indexing in parallel. First, spatial data is partitioned and indexed in a Hadoop MapReduce cluster. Two main partitioning strategies are evaluated: a) A linear-complexity method based on Zorder values, and b) An iterative algorithm based on X-means clustering. The advantages and drawbacks of each method are weighted in with relation to query performance. Second, interactive queries are processed from a local site using the index data structures built in the Cloud. We perform an experimental study on a real dataset of 110 million spatial objects representing property parcels in the United States. Our results support Cloud computing as an effective technology to cope up with huge datasets and, in particular, MapReduce parallel programming model in easing parallel processing implementations. © 2010 IEEE.
