HOW TO CREATE A NETWORK DATASET ON ARCGIS

GIS networks consist of interconnected lines (known as edges) and intersections (known as junctions) that represent routes upon which people, goods, etc. can travel.

I will be showing you how to do this using 2 methods.

The first one will be done using a road network shapefile and the second one will the done using a feature dataset that contains a road network.

Introduction to Network Analysis

GIS networks consist of interconnected lines (known as edges) and intersections (known as junctions) that represent routes upon which people, goods, etc. can travel.

The object traversing the network follows the edges, and junctions appear when at least two edges intersect.

Junctions and edges can have certain attributes affixed to them that increase the cost of traveling in the network, known as impedance. For example, a road network can have speed limits attached to the edges, and a junction can prevent left turns.
