If you’re working with the Azure Maps Web SDK and want to customize the road_shaded_relief basemap, it’s important to have a reliable understanding of all the style layers and their source layer names. Relying on map.map.getStyle().layers can give you the current layers loaded in your browser, but it might not be the most dependable or official source for this information.
To get a more stable reference, you’ll want to look for an official style JSON that describes the basemap. Some mapping services provide a published style JSON file that details all the layers, their IDs, and how they are styled. Check the Azure Maps documentation or GitHub repositories—they sometimes contain published style JSON files for their services.
Look for documentation or resources that list all layer IDs used in the road_shaded_relief basemap. These lists help you understand what each layer represents, such as country boundaries or major roads. Knowing the layer IDs makes it easier to target specific features without relying solely on browser-loaded styles that might change over time.
Furthermore, understanding the underlying vector tile schema is helpful. This schema provides details on how features are organized within the tiles, and knowing this can assist in customizing your map more precisely.
If the layer IDs are not guaranteed to be stable over time, the best approach to target specific features is to use feature filters or expressions based on properties within the features, such as feature class or layer name attributes. Instead of relying solely on layer IDs, you can filter features within a layer dynamically based on their properties, ensuring your targeting remains accurate even if internal layer IDs change.
In summary, check for official style JSON files, review the documentation for layer IDs, and consider filtering features by their properties to reliably customize your map layers. This way, you ensure your customization remains robust and future-proof.
