OOM Live-Updating

OpenOrienteeringMap now updates in near-real-time from the OpenOrienteeringMap database. It does what’s called “minutely” updates, although the actual time-lag from updating something in OpenStreetMap (say, using Potlatch), to it appearing in OpenOrienteeringMap, is typically around five minutes – occasionally the delay may be up to 15 minutes, or the update doesn’t appear at all if something wrong happens. This is, however, a vast improvement on the per-month updating I was doing before – that process took a couple of days to run, this only takes a few seconds each minute.

Note if you are viewing OOM in your browser, your browser will probably cache the tiles, including ones which have since been updated, so you will want to do a “super-refresh” of the page (Control+Shift+R) or reopen your web browser, if you’ve made changes and want to see them reflected. Creating PDF maps always uses the database so doesn’t suffer from this caching issue.

A huge amount of adding and updating is going on around the world in OpenStreetMap – the project is growing by around 5% a week – so it’s good to be able to take advantage of people’s efforts on a timely basis.
