Architects, surveyors, planners and most property practitioners use maps in their day-to-day professional lives.
The vast majority of these maps will be directly or partially based upon Ordnance Survey (OS) mapping data. Whether these maps are accurate, up-to-date, correctly scaled or even licensed may be unknown and it is down to the user to ensure the maps are fit for purpose and that they are adequately licensed.
