I am looking for a possibility to display only roads of a certain surface (asphalt, gravel…) to be displayed. Either all other roads with other surfaces should be hidden or my searched surface should be highlighted in color.
I would be very happy about your help.
Overpass Turbo or JOSM filters are typical solutions. (If more info is needed than just names: please write a comment)
StreetComplete android app with is surface overlay may be also good enough.
