I updated some roads in osm map. I updated using JOSM. But the updates are not visible in the map after 2 days. I am new to osm maps. Can anyone please tell me the possible reasons.
Generally, your edits will appear on the default mapnik layer on osm.org within several minutes or hours.
However, there's a few reasons why your edits haven't appeared: - the tags that you used are incorrect; some obscurer features (for example, a power generator) don't render (appear) on the default mapnik later used on osm.org.
This QandA discusses these reasons and others more in-depth.
