General

Mapbase Maintenance (MBM) has responsibility for several areas of work:

  • To act as liaison with the Ordnance Survey (OS) regarding survey requisitions, digital enquiries and supply of all OS products, ensuring that the quality of services and products provided is satisfactory.
  • To monitor and negotiate costs for the services and products provided by the OS.
  • RCIL indexes. 


Main aims and objectives

  • To investigate and, where practicable, resolve discrepancies with registered cadastral units and indexes arising from updates received as a result of receiving new data from the OS.
  • To, where possible, improve turnaround times for the various casework types being processed, including monitoring OS’s response to survey requisitions, street survey checks and requests for topographic information.
  • To monitor the incidence of survey requisition in particular areas and regulate the quality of resultant OS data to ensure a high level of service is maintained.
  • To work in partnership with internal customers to help improve services and the quality of products supplied to external customers.

titleTimescales for obtaining new OS data

The OS continuously revise the map in urban, rural and moorland areas to capture major change such as housing developments, commercial developments and road/rail infrastructure. Their published time scale for picking up the new data is within 5 months of notification of completion.

As new build may be captured by either ground or aerial survey methods, it is possible that there may be some slippage in the published time scales, i.e.

  1. Aerial photography - the flying season is weather dependant.
  2. External contractors do some surveying.
  3. Local staffing resource issues.
  4. Unforeseen circumstances e.g. foot and mouth outbreak.

titleNational Library of Scotland (Map Library)

The National Library of Scotland in Edinburgh holds copies of all the available editions of published National Grid OS maps for Scotland. If a caseworker needs an edition to help resolve an extent discrepancy, they should forward their request to the MBM manager. MBM will attempt to batch any requests, unless urgent, in order to save on postage and packaging. The caseworker will be kept informed of progress.
