Is it not possible to make a automatic legend for the base maps? I wanted a legend to show the features of the strett base map.
Any suggestions and recommendations to achieve this would be very much appreciated!
You would have to create your own layers showing the features that you want, probably in vector form. Is it street names? what are you trying to show that isn't readily acertained from the basemap? Remember it is just that... a basemap... a reference... upon which one can display the information that is being mapped
Street maps are cached map/ Tile service which converted to pixel.
In that you can't edit properties of it.
If you really want to do then use
Please use your own data to create base map services and use it as you like.
Just my understanding!
