Why cant I access individual layers in the base map, like roads?
All the data that you see in the base map (Map button on top right), roads, streams, place names, county, city, town and parcel boundaries, water, military bases, etc., are all combined in such way that they not individually selectable. In effect, they have been placed into a single layer with no direct control. The only control the user has is to select between the Map or Satellite buttons (top right).
