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.
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 - How does a school system determine school bus routes and schedules?
is usually used by organizations/agencies that manage or use networked facilities, such as utility, communication and transportation systems.
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.
Network analyses involve analyzing the flow of networks-a connected set of lines and point nodes (sometimes called centers or hubs).

Specialized queries that reference connected linear and node features.
A composite layer that contains the properties and classes used in the analysis of a network problem, and the results of the analysis.
Network Analysis The technique utilized in calculating and determining relationships and locations arranged in networks, such as in transportation, water and electrical distribution facilities. Node ...
Raster values can be transferred to vector maps with v.what.rast and v.rast.stats.

[LINK] The locations of fire stations were plotted on the road network, and a GIS function called network analysis 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, , neighborhood operations, ...
Many applications of graph theory exist in the form of network analysis. These split broadly into two categories.
In particular, (e.g., finding the best route from one location to another) and measurement (e.g., finding the length of a river segment) relies heavily on the concept of to- and from-nodes and uses this information, ...
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.
Extensions add more capabilities to ArcGIS Engine such as 3D, spatial, and network analysis; schematic data management; data interoperability; and asset tracking in time and space.

Connectivity - A topological relationship that occurs when arcs are connected using shared nodes. Connectivity is used for network analysis 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 .
