Network analysis

In this exercise you will create a network dataset from a polyline road dataset extracted from the US Census.

  • Ensure that the network analyst extension is enabled.
  • Create a new file geodatabase for this lab (this may have already been done when you started ArcGIS Pro).
  • Create a new feature dataset called “voting” within your file geodatabase. Set the CRS to Wisconsin State Plane Central (EPSG: 32153).
  • Import the Q:\StudentCoursework\Haffnerm\Data\ec_roads.shp shapefile (roads in Eau Claire) into the feature dataset and call it “ec_roads”.

Next, you will create a network dataset in the feature dataset. If the option is greyed out, be sure to enable the Network Dataset extension. Use the following options:

  • Set the Target Feature Dataset to “voting”.
  • Set the Network Dataset Name to “ec_roads_nd”.
  • Set the Source Feature Class to “ec_roads”.
  • Select “No elevation” for the Elevation Model.

After this, return to the Catalog and right click on the network. Select “Properties”. Go to the “Source Settings” menu option from the left pane, and click on “Group Connectivity”. Then, change the Policy from “Endpoint” to “Any Vertex”. Then, click ok. Right click on the network again and click “Build”.
