Book Description
Spatial networks like road networks, pipeline networks, transportation networks, and power network are being increasingly used in the fields of route planning, land use planning, city planning, traffic forecasting thus promising the generation of vast amounts of spatial networks data. While in order to efficiently handle, represent, store, query, and manipulate large spatial networks database support is a must, database support for spatial networks is rare. Our project aims to provide a conceptual, abstract, and formal model of spatial networks, called Spatial Network Algebra (SNA), that includes types, operations, and predicates and can serve as a specification for their later implementation in spatial database systems and GIS. Based on this abstract model of spatial networks, we will create an implementation of a spatial network data type which we will incorporate in a spatial database. In the context of spatial databases retrieval and handling of spatial networks through querying becomes critical to exploiting the functionality of database. Thus query mechanisms which are able to handle the complexity of spatial networks data becomes essential. Consequently, we show how our spatial network concepts can be embedded into an SQL-like query language.
