Configure basemap style parameters

Apply basemap style parameters customization for a basemap, such as displaying all labels in a specific language or displaying every label in their corresponding local language.

Configure basemap style parameters

Use case

When creating an application that's used in multiple countries, basemaps can reflect the languages and cultures of the users' location. For example, if an application user is in Greece, displaying the labels on a basemap in Greek reflects the local language. Customizing the language setting on the basemap can be controlled by an application user (such as by setting preferences), or implicitly managed within the application logic (by querying the locale of the platform running the application).

How to use the sample

This sample showcases the workflow of configuring basemap style parameters by displaying a basemap with labels in different languages and launches with a Viewpoint set over Bulgaria, Greece and Turkey, as they use three different alphabets: Cyrillic, Greek, and Latin, respectively. By default, the BasemapStyleLanguageStrategy is set to Local which displays all labels in their corresponding local language. This can be changed to Global, which displays all labels in English. The SpecificLanguage setting sets all labels to a selected language and overrides the BasemapStyleLanguageStrategy settings.

Pan and zoom to navigate the map and see how different labels are displayed in these countries depending on the selected BasemapStyleLanguageStrategy and SpecificLanguage: all English, all Greek, all Bulgarian, all Turkish, or each their own.

How it works

  1. Create a BasemapStyleParameters object.
  2. Configure customization preferences on the BasemapStyleParameters object, for instance:
    • setting the LanguageStrategy to BasemapStyleLanguageStrategy.Local or
    • setting the SpecificLanguage to a new CultureInfo("el") changes the label language to Greek.
  3. The SpecificLanguage always overrides the LanguageStrategy, which means the specific language needs to be set to an empty string in order to use the language strategy.
  4. Create a basemap using a BasemapStyle and the BasemapStyleParameters.
  5. Assign the configured basemap to the Map's Basemap property.
  6. To modify the basemap style, for example if you want to change your preferences, repeat the above steps.
