Peer to peer technology plays an important role in spatial data sharing because of its distributed and decentralized nature. In spatial P2P each peer stores a part of the available spatial information and runs software with equivalent functionality rather than through a central server. Spatial P2P is dynamic in nature where the network structure is always changing. Spatial objects are having distinct properties like identity, location and relationship among them and spatial data is multidimensional. Spatial data sharing process like storing, querying and retrieving large amounts of data is a complex task. It requires the potential of preserving multidimensionality of heterogeneous spatial data without the time complexity and load balancing.
