Our OpenStreetMap (OSM) maps our continually updated on a drip-feed basis from the master OSM dataset, but they may take up to 3-4 days to refresh on your device, as the map tiles are cached by your browser and our server. Clearing your browser's cache would result in the latest set of map tiles being requested, but you may need to revist the map again a few minutes after this if fresh map tiles need to be regenerated on our server.
Please note, map updates will take longer to apply to the routing engine - see our FAQ on routing updates for more details on this.
We have a number of detailed guides giving instructions on how to use many of the features of plotaroute.com.
We have a number of video tutorials demonstrating how to use key features on the site.
