How frequently will OS MasterMap Imagery Layer be updated?

The Imagery layer provides full coverage of Great Britain, England, Scotland and Wales.  We continuously refresh this on a cyclic schedule based on levels of expected change utilising our knowledge of change intelligence. Imagery is captured as part of our integrated revision programme which updates imagery alongside our detailed data, notably OS MasterMap® Topography Layer.  This ensures that the layers are synchronised when used together.

We typically plan to fly 70 000 sq km during the flying season, from April until November each year. Achieving our update targets will, of course, be dependent on weather conditions, quality checks and flying restrictions. Thus we are unable to guarantee imagery captured until it has been successfully processed.

Throughout the period of your imagery contract any newly captured and processed data made available to order can be tracked using the currency map which is updated monthly.
