Openstreetmap images missing from network object


The background of a WinUI network widget does not display a map anymore. The background is provided by OpenstreetMap.


OpenstreetMap provides a tile or WMS service free of charge. The “free of charge” provision assumes a fair use policy; if you are using the application heavily, you will need to take a subscription, see also OpenstreetMap Acceptable Use Policy

Heavy use of other similar services by other providers will also require that you to take a subscription!

The AIMMS WinUI provides software to deploy these GIS services but the AIMMS WinUI does not provide these services themselves.

More information to change to a new service can be found via: Aimms Menu > Help > Contents and Index, and then search for GIS.

Selected other services

  1. Bing provides their service free or subscripted, see also: Microsoft Bing Maps Platform APIs Terms Of Use and Microsoft Bing licensing options


    Nowadays most web services use an apikey to log in, instead of a username/password. The apikey can be filled in in the username field in the Authentication of a GIS Source:


    Here the sp_BingApiKey is a string parameter holding the apikey you received from Bing.

  2. Mundialis provides the information together with OpenstreetMap:

  3. Yahoo no longer provides a map tile server. In the AIMMS WinUI, the type “Yahoo” is translated to “OpenstreetMap”.
