A technique for resampling raster data in which the value of each cell in an output raster is calculated using the value of the nearest cell in an input raster. … Read more

[cartography] The border delineating and defining the extent of geographic data on a map. It demarcates map units so that, depending on the map projection, the neatline does not always … Read more

[mathematics] Methods of defining new values for locations using the values of other locations within a given distance or direction.

[programming] An open-source development environment that supports all Java application types.

1 [network analysis] An interconnected set of points and lines that represent possible routes from one location to another. For geometric networks, this consists of edge features, junction features, and … Read more

[network analysis] Any method of solving network problems such as traversability, rate of flow, or capacity, using network connectivity.

[ESRI software] In ArcGIS Network Analyst, a feature class or table containing network analysis objects that is stored within a network analysis layer. Network Analyst solvers read input from, and … Read more

[ESRI software] 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.

[ESRI software] In ArcGIS Network Analyst, a feature or row in a network analysis class. Network analysis objects are used as input and written as output during network analysis. A … Read more

[ESRI software] An auxiliary or additional function performed by a junction feature within a geometric network. Junction features can act as sources or sinks for calculating flow direction. If a … Read more

[ESRI software] A type of attribute associated with a network element in a network dataset. Network attributes are used to help control flow through a network (similar to a weight … Read more

[ESRI software] A collection of topologically connected network elements (edges, junctions, and turns) that are derived from network sources, typically used to represent a linear network, such as a road … Read more

[ESRI software] A component in a network dataset: an edge, junction, or turn. All elements in a network dataset share the same set of network attributes. Network elements are used … Read more

[ESRI software] A component in a geometric network: an edge or a junction. Features in a geometric network are used to model topological relationships, typically in directed flow networks such … Read more

[ESRI software] A layer that references a network dataset. In a geodatabase, a network dataset is a collection of network elements (edges, junctions and turns) that are derived from network … Read more

1 [network analysis] A geographic position in a network system. 2 [ESRI software] In ArcGIS Network Analyst, a type of network analysis object that is zero-dimensional and has a defined … Read more

[ESRI software] A connecting point in a geometric network, such as an intersection or interchange of a road network, confluence of streams in a hydrologic network, or switch in a … Read more

[Internet] A number that is used to specify direct communication over a network to an Internet application.

[ESRI software] Feature classes in a geodatabase that are used to generate and define a network dataset.

[network analysis] A function that performs network analysis on a geometric network. Specific kinds of network tracing include finding features that are connected, finding common ancestors, finding loops, tracing upstream, … Read more

[computing] A computer architecture modeled after the human brain and designed to solve problems that human brains solve well, such as recognizing patterns and making predictions from past performance. Neural … Read more
