Service Description: The Vector base map service for The National Map is in the Web Mercator Auxiliary Sphere projection and is split into two services: TNM_Vector_Small is tiled for the small scales, down through 1:18,000, and TNM_Vector_Large is dynamic, for scales 1:9000 and larger.
The data sources are: National Atlas - small scales, and National Map - large scales.
