Rotate, shift, scale network

You can do the following to the entire network model:

  • Rotate
  • shift horizontally and/or vertically
  • Scale

You can combine the functions with one another and execute them at the same time.

Notes: If you rotate or shift a network with any other coordinate system than the Visum one, the reference to real coordinates is dropped. The active coordinate system is deleted and reset to the standard Visum coordinate system.

Any backgrounds displayed with the aid of a reference point are shifted (Using backgrounds in the network display).

1.  From the Network menu, choose Network settings.

The Network settings window opens.

2.  Select the Co-ordinate system tab.

3.  Click the Transform network co-ordinates button.

The Transform network co-ordinates window opens.

4.  Make the desired changes.

Element

Description

Center for transformation

For a transformation of coordinates you can choose between the network center point and a user-defined coordinate as center.

Note

The center of the transformation is the coordinate that will not change with scaling and rotation.

Network center point

The center of the network is used for the transformation.

User-defined

Enter the X-coordinate and the Y-coordinate of the desired center point.

Transformation parameters

Scaling factor

Value with which the network is scaled

  • Values less than null zoom out the network
  • Values above null zoom in the network

The scale of the network will not be changed.

Rotation angle (degree)

Angle in degree by which the network is rotated

Note

For an angle between 0 and 360° the rotation is clockwise, for an angle between -360° and 0 the rotation is an anti-clockwise.

Shift X

Offset by which the network is shifted horizontally

Shift Y

Offset by which the network is shifted vertically

5.  Confirm with OK.

6.  Confirm the query with Yes.

The network is rotated and/or shifted.
