I'm new in using JOSM and OpenStreetMap data . I import a shapefile of highways in JOSM and use it for styling the highways.Some highways are trunk ( in open street map standard ) and some of are primary . When i style highways, the name of highways display in zoom level of 17 on map . I want to labeling the highways in zoom level of 12 .
How can i change the zoom level for name of the highways?
