I have some links to Google Maps that I want to replace with OpenStreetMap ones. They are of this form. I can enter the postcode into OSM, zoom in to show individual buildings, Share and 'include marker' to get a link like this It looks much better than the Google version. Only problem, I have 200 of them to convert! Is there a way to generate the OSM links from the UK postcode? Looking up the lat/long coords for each would be a pain and would require some scripting, and ideally I can generate usable OSM links by inserting the postcode itself. But whenever and whatever I try, I don't get a permanently visible marker, and the zoom level is great for mountain ranges, not so much for the individual streets I'm interested in.

Well, I can only conclude that this forum is very inactive!

I think therefore that the answer is 'no', and that the solution requires the postcode to be replaced by its lat/lon coordinates. I think I have a practical way to do this and will post it here when I've tested it.

UK postcodes are particularly patchy in OSM as they are rarely signposted and there often seem to be issues with the "open" database releases.

This is what I did! There were 1200 postcodes not 200, but this is seemed appropriate technology for the task.

I extracted the postcodes, one to a line.

I pasted them into Chris Bell's excellent Batch Geocoder, selecting Comma-separated and Input postcode, to give output lines of the form "AB24 3TU",57.166749,-2.104203

I converted these with find-and-replace in an editor into the PHP code for an associative array and wrote a PHP script to insert map links in the format https://www.openstreetmap.org/?mlat=$lat&mlon=$lon#map=17/$lat/$lon where 17 is the zoom level and $lat and $lon are the values in the second and third CSV fields.

Obviously there are many other ways to get the same result but this worked for a one-off job of finite size.
