[Mailman] Question

[jfh van der Boor]

Hello,

I wanted to ask a question.
Is it possible to create a layer of your own in OpenStreetMap.
for instance:
if you zoom in on the map, we see small icons of all sorts of shops.
The question is, is it possible that we do not see it, and the color of the substrate can 
it be adjusted in a base map that is suitable for our own purpose in a separate layer

am looking forward to the answer

greet
