Ordnance Survey has quality control procedures built into each production stage to ensure the information on our maps is to the highest practicable standard of accuracy.
Customers can expect a quality product.
Undertake all surveys necessary for the maintenance of the archive of trigonometrical, levelling and topographical information of Northern Ireland to standards which are defined in the Instructions to Surveyors. These standards are reviewed continually through consultation with users to ensure that their requirements for content, accuracy and currency are maintained. Provide timely and accurate information from the archive to our customers in forms most appropriate to their needs. Produce maps at various scales on high quality paper or plastic material using processes which best retain the accuracies to which the topographical features were surveyed. These maps are designed to standard specifications to ensure that topographic features are clearly depicted and names are legible.
