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 ] ...

Network Analysis
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. See Flow Analysis, Routing, and Optimum Path Analysis.

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, such as the circuits of a road or utility network. Abbreviated NA.

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

[ESRI software] In Survey Analyst for field measurements, a window that displays information about the computation network, such as breaks in the sequence, computation states, and computation network cycles.

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

Network Analysis
Network analysis is usually used by organizations/agencies that manage or use networked facilities, such as utility, communication and transportation systems. Utilities use network models to monitor and analyze their distribution systems and meter-reading routes.

Network analysis
One of the most far-reaching applications of GIS is in network analysis. Network analysis is the mathematical processing of the geometry of a link/node layer, enabling the identification of all possible routes around that network, along with the distances and times involved.

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 Analysis
Network analyses involve analyzing the flow of networks-a connected set of lines and point nodes (sometimes called centers or hubs).

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
The beginning or ending location of a line.
The location where lines connect.

Vector-Raster queries
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 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, network analysis, neighborhood operations, and common statistical procedures under the spatial analysis heading.

Many applications of graph theory exist in the form of network analysis. These split broadly into two categories. Firstly, analysis to determine structural properties of a network, such as the distribution of vertex degrees and the diameter of the graph.

In particular, network analysis (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, along with attribute information, to calculate distances, ...

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 network analysis to derive new information to aid in problem solving and planning.

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 a two dimensional model all line crossings are considered as nodes. 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.
