Map Service Name: World_Dark_Gray_Reference
Description: This map service provides labels for selected cities, towns, and neighborhoods around the world, in support of the World Dark Gray Base map. Together they draw attention to your thematic content by providing a neutral background with minimal colors, labels, and features. Only key information is represented to provide geographic context, allowing your data to come to the foreground.
