I can check later though. Hello Andy, To follow up on this: the total size of all the PBF files I use to populate the Freemap database is 294MB, compared to 524MB for the complete OSM extracts for the whole of England and Wales. So a machine with perhaps 2-3x the RAM and disc space (for caching) of the above might do it for the UK. Thanks, Nick
