Positional accuracy improvementOrdnance Survey has delivered an updated version of its rural mapping, with improved positional accuracy, on a national basis. This has moved all of the rural features in the database in a pseudorandom way, which has had a significant impact on our data with the representation of topographic features that symbolise property boundaries moving in an unpredictable way. We are now well into a defined programme of work to shift our data in sympathy with Ordnance Survey’s changes. This programme will take until the first quarter of 2008 to complete. |
