Workshop on
Optimal Data Structures for Efficient Organization and Retrieval of Massive Spatial Data
When: Thursday, June 10 and Friday, June 11, 2010
Where: Fredericton,
New Brunswick, Canada
Location: Gillin Hall,
540 Windsor Street, Room GC-127
Aims and Scope
This workshop explores recent progress and open problems in optimal approaches for storage, retrieval and dynamic updating of spatial data in a networked environment. Topics to be addressed include
- The design of spatial data structures and algorithms for geographic information systems that have as low a memory footprint as possible and still allow operations such as node addition and removal, node locking, and range queries to be performed efficiently.
- I/O aware spatial data structures that are sensitive to varying access costs across the memory hierarchy, including issues related to the cost of distributed, remote and secondary storage.
- Caching strategies for distributed spatial data structures that to coordinate paging of indexing structures in order to reduce external (network or disk) accesses given changes in user requests.
- Issues of consistency, replication and recoverability in distributed massive spatial data structures.
- Data management and organization of geo-spatial data in ways that maintain efficiency of access, accuracy of data, as well as the ability to distribute the data.
- Design of data structures for storing massive amounts of data that can be readily distributed over a network.
