Managing map services of the background map

You may use map services to dynamically or statically embed background maps.

In addition to the default PTV map services, you can also insert WMS map layers or tile map layers. You cannot delete or edit the default map services.

Note: In Visum, WMS are supported from version 1.1.1.

Importing map services

You can exchange map services in *.xml data format by importing or exporting them together with the user settings (Saving, opening and restoring user preferences). This way you can also use map services exported from Vissim.

1. From the Edit menu, choose User preferences.

2. Click the Open button below the navigator.

3. Open the desired XML file.

The imported map services are shown in the list.

Inserting WMS map layers

The WMS map layer window opens.

4. Click the Create new connection button next to the WMS connection drop-down list or select an existing connection.

The WMS connection window opens.

5. Enter the Internet address of the desired WMS service in the Base URL field.

6. Click Connect.

If the connection is successful, basic information such as the name and description of the service is displayed.

7. Confirm with OK.

The data of the service are displayed in the WMS map layer window.

If a layer is selected that contains subordinate layers, all subordinate layers are automatically included in the map. The Description area displays the name and description of the selected layer.
Selected layers	The list of selected layers shows the title of the layer in the first column and the assigned style in the second column. You can assign a style to each layer. For more information about layers and style, see the tooltip in the third column. Use the arrow symbols to define the drawing order of the layers.
Preview	Display of a map section according to the current settings Update The data in the window is not updated automatically. Use this button to refresh the preview.
Co-ordinate system	Select the desired co-ordinate system. All co-ordinate systems that are available for all layers can be selected here. The output projection of the program is recommended.

Inserting tile map layers

3. Click the symbol next to the Create WMS map layer button.

4. Select Create tile map layer.

The Create map layer window opens.

5. Make the desired changes.

Element	Description
Name	Unique name of the map layer
URL template	URL template for the map layer, including prefix for its service type: tile(s):// for map services that provide maps as tiles in various zoom levels (tile service). Notes The prefix tile(s):// replaces the beginning of the base URL http(s):// here. You can also use WMTS services that support the Well-known scale set GoogleMapsCompatible. http(s):// for Web Map Services (WMS) You need to work with placeholders in the URL template, which will then be automatically replaced with up-to-date values when the maps are downloaded. The following placeholders are required in the URL template of Map Tile Services: %TX%, %TY% for the tile index %TZ% for the zoom index %TQUAD% for the quadkey if used by the map tile service. Note Quadkeys are used for the economic indexing of tiles of various zoom levels in databases. Microsoft Bing Maps, e.g., uses quadkeys. %SUBDOMAIN% if required for alternative subdomains of the map service. If you want to use this placeholder, the Subdomain list box must contain entries. The following placeholders are required in the URL template of Web Map Services (WMS): %WIDTH% and %HEIGHT% for the image size in pixels %BBOX% for the window coordinates or alternatively %LEFT%, %TOP%, %RIGHT% and %BOTTOM% for the window coordinates. Notes: When using alternative placeholders, please note that in Visum %TOP% is used for yMin and %BOTTOM% is used for yMax. We recommend using the placeholder %BBOX% for the window coordinates.
Subdomains	Comma-separated list of subdomains available Note Some map services provide alternative URLs that are addressed by a URL prefix or suffix. Use cases for this are e.g. parallel URL download or omission of a URL.
Confirming license terms and conditions of use	Accept the terms of use and license before using a map service.
