One Scotland Mapping Agreement

IS Spatial Hub on Twitter

The One Scotland Mapping Agreement (OSMA) came into operation in April 2009 as a single agreement through which local and central government in Scotland access Ordnance Survey mapping products. Subsequently, data from suppliers other than Ordnance Survey have been added.


The agreement with Ordnance Survey is a crown to crown agreement, which removed the requirement for the costly procurement exercise associated with the previous agreements. 73 organisations were founding OSMA members and enjoyed open data sharing amongst each other. OSMA significantly increased the take up of spatial data products at no additional cost to organisations.


In its first four years, OSMA was extended to over 100 member organisations and removed the previous barriers to data sharing restrictions between members. This has led to a threefold increase in the use of spatial data within the public sector.


In 2013 a revised OSMA was signed, following on from the success of the original agreement. This is a 10 year agreement to reflect the stability and the dependence on OSMA products by all member organisations. The new agreement was intended to deliver benefits to both sides and make various efficiency savings.


OSMA is funded by member organisations. The various sectors (Scottish Government and agencies, local government and NHS) all contribute an agreed percentage.


Sample usage of Ordnance Survey products under the OSMA:


  • Registers of Scotland depend on OS mapping to register the 78,000 property transactions (with a value of £11Billion) last year. Every title is referenced against Ordnance Survey mapping.
  • The Scottish Neighbourhood Statistics are all based on data derived from OS products and are used to support decision making on public sector spending, including community partnerships with NHS and local government.
  • Transport Scotland relies on OS mapping for planning major infrastructure initiatives, such as the design for the dualling of the A9 from Perth to Inverness and the Queensferry crossing.
  • Scottish Environment Protection Agency (SEPA) and Scottish Natural Heritage (SNH) depend on OS products for Scotland’s environment management, including statutory functions such as the Flood Prevention Act (Scotland) and INSPIRE.
  • Local government and emergency services: Local government uses OSMA products to support services such as ground maintenance (£192M), street cleansing (£192M), schools transport  (£384M), planning and development (40,000 applications pa), and roads maintenance (£650M). These are only examples but the total figure for services supported by OSMA is well over £1.5 billion.
  • Emergency services depend on OS products for all command and control applications, operational planning and crime pattern analysis as well as for data sharing with community planning partners.
