Network Analysis
network analysis - [network analysis] Any method of solving network problems such as traversability, rate of flow, or capacity, using network connectivity. [Category=Geospatial ] ...



A spatial analysis function that uses the topological structure of lines to follow a path along an interconnected network and then process attribute data associated with the line segments.

Network analysis
The GIS process providing analytical techniques for geographic or statistical analysis of relationships and flow that are dependent on the connectivity of segments and nodes in a linear system, ...

can be performed on a transportation network over the web by hosting services on ArcGIS Server.

Network Analysis Network analysis is commonly used for the analysis of moving resources from one location to another through a set of interconnected features. It includes determination of optimum paths using specified decision rules.

- How does a school system determine school bus routes and schedules?

Network analysis
One of the most far-reaching applications of GIS is in network analysis.

is a range of techniques employed by engineers and planners to study the properties of networks including connectivity, capacity, and rates of flow.

Specialized queries that reference connected linear and node features.

network analysis layer
A composite layer that contains the properties and network analysis classes used in the analysis of a network problem, and the results of the analysis.

Raster values can be transferred to vector maps with v.what.rast and v.rast.stats.
Vector network analysis
GRASS provides support for vector network analysis. The following algorithms are implemented: ...

[LINK] The locations of fire stations were plotted on the road network, and a GIS function called was used to calculate the time necessary for emergency vehicles to travel from the fire stations to different areas of the city.

Star and Estes (1990) group many spatial data processing operations and traditional spatial analysis tools such as overlay, spatial aggregation, buffering, network analysis, neighborhood operations, ...

Many applications of graph theory exist in the form of . These split broadly into two categories.

Most GIS users are familiar with network analysis that accepts starting and ending locations and then determines the best route between the two points along a road network.

Modeling: Applying structured rules and procedures to one or more spatial database overlays to conduct spatial and/or to derive new information to aid in problem solving and planning.

Compiled over 30 years and first published in 1984, the book contains more than 10,000 terms embracing all aspects of geoprocessing and geoanalysis, spatial and network analysis, resource management, facilities management, automated mapping, ...

Connectivity - A topological relationship that occurs when arcs are connected using shared nodes. Connectivity is used for in geographic data processing. See also Topology.
...

In the same time these lines are often crossing only in projection on the plane, but not in reality (e.g. multilevel crossings). In such cases the explicit topology storage is the only way that enables the network analysis.
