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.

Use case

When creating an application that is 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 near Athens, Greece. By default, the BasemapStyleLanguage 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 specific option sets all labels to a selected language and overrides the BasemapStyleLanguage settings.

Pan and zoom to navigate the map to neighboring countries that use different alphabets, such as Bulgaria, and Turkey, to see how different labels are displayed depending on the selected BasemapStyleLanguage: 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 BasemapStyleLanguage to local or
   • specific("el") changes the label language to Greek.
3. Create a basemap using a Basemap.Style and the BasemapStyleParameters.
4. Assign the configured basemap to the Map’s basemap property.
5. To modify the basemap style, for example if you want to change your preferences, repeat the above steps.

About the data

The main data for this sample is the BasemapStyle, which includes basemaps that support both language localization and global language setting. The supported languages, along with their language code, can be found in the API’s documentation.
