Customizing the Network Layer

The network layer is the primary map layer, and is composed of linear features such as arterial roads, residential streets, rivers, and railways.

Before you begin

The Layer Control dialog box must be open.

Procedure

  1. In the Static Map Layers list, select the network check box.
  2. In the Feature Type list, click the network type that you want to change.
    For example, the Layer Control dialog box shown in Defining Map Layers shows the settings for roadways with Limited Access (major highways/interstates).
    The following options override the settings for each individual network feature type:
    Select All
    If selected, all of the network feature types are simultaneously selectable. If this check box appears selected but shaded, there is at least one feature type whose Selectable check box is clear.
    Show All
    If selected, all network feature types are displayed. If it appears selected but shaded, there is at least one feature type set to Threshold or Do Not Display.
  3. Select any of the following:
    • Do Not Display
      Hides the feature type completely from view.
    • Display Always
      Shows the feature type regardless of the threshold setting of the map.
    • Threshold
      Shows the feature type only when the map appears at a specific threshold.

      For example, the Limited Access feature type appears at a threshold of 20000 and lower. At a greater threshold than this, it is not displayed on the map. (The threshold unit is in meters.)

    • Selectable
      Makes the selected feature detectable to functions within the system map itself, and to other Trapeze products.

      For example, within the system map, it allows the name of that feature to be displayed when it is selected. It also makes the feature detectable to the Distance Wizard Tool in the Trapeze4 Workstation.

  4. In the Line Style frame, edit any of the following:
    • Width
      Defines the line width of the feature.
    • Color
      Defines the color to be displayed on the map.
    • Style
      Defines the line patterns (for example, dotted or solid).
  5. In the Outline frame, edit any of the following:
    • Threshold
      Defines the threshold at which the border appears on the map.

      The Outline threshold should not be greater than the main threshold.

    • Color
      Defines the color of the outline of the feature.
    • Width
      Defines the line width when the map appears at the Outline Threshold.
    • Border Width
      Defines the width of the outline. All widths are expressed in pixels.
  6. Click OK.
