Deactivating by length

Sometimes, the inappropriate links created in initial spatial networks are very long. This can occur when the network links areas on the edge of the study area to other edges, when the intervening area was not actually a part of the study. To select all "long" links at once, you can use the "Minimum Length" option. Steps for this process are listed below.

1. When you choose to edit the network, BoundarySeer automatically goes into edit mode.  First, select a link that you want to represent the minimum length for all of the links that will be selected (and eventually deactivated).

2. From the Spatial Network menu, choose "Minimum Length". Or, hit the minimum length toolbar button.

3. All of the links longer than the chosen link will change color. The default colors for spatial networks is green for active links, gray for inactive links, and orange for selected links. These colors can be changed by the user.

4.  Next, from the Spatial Network menu, choose "Deactivate". Or, hit the deactivate button.

   The links that were orange turn to gray, and are prevented from being included in later analyses.

5. If you want to add some of these links back into the active set, either double click them, or select them with a left mouse click, and then choose "Activate" from the Spatial Network menu or hit the Activate button.

6. Choose "Save Changes" from the Spatial Network menu, hit the "Save changes" button , (or wait for the prompt at the next step).

7. Then choose "Stop editing" from the menu or from the toolbar , which will turn off the edit mode. You can also stop editing by deleting the network layer from the map. BoundarySeer will prompt you to save your changes.
