Boundary disputes
Vector basemap service layers can be configured to display disputed boundaries according to a specific world view. This requires modifying the style definition JSON.
The source Esri Community Map data used to build the vector tiles has disputed boundaries defined for many areas around the world. In the Esri vector basemaps, internationally recognized national boundaries (e.g. United States / Canada border) are typically represented with different types of “solid” lines while disputed boundaries (e.g. parts of French Guiana / Suriname border) are typically represented with “dashed” lines. In some cases, a country will want to not render (i.e. make invisible) a disputed boundary that it does not recognize. See this blog for an example of how to change the JSON code and apply the DisputeID code in the filter for boundary lines.
Visit this web map to view details of all the disputed boundaries, with DisputeID codes, configured in the Esri Vector Basemaps.
Worldview
The new worldview query parameter allows you to display country boundaries and labels based on a specific view of a country.
Worldviews can only be specified for key ArcGIS basemap styles (OSM is not supported). When a specific worldview is chosen, it is possible for some labels to change language. However, when the language query parameter is used in combination with the worldview selection, the explicitly selected language will take priority over any language changes associated with the worldview.
