§ 40. Mr. Peter M. Jackson
asked the Minister of Housing and Local Government how many revisions of the 1 inch and 2½inch ordnance surveys have been undertaken during the course of the last 30 years; and on what date it is proposed that future revisions be undertaken.
§ The Joint Parliamentary Secretary to the Ministry of Housing and Local Government (Mr. Arthur Skeffington)
The 1 inch maps are fully revised at intervals of 7, 15 or 25 years according to the amount of change and the demand 25 for individual sheets. Between these full revisions, partial revision is made to take account of significant changes. The 2½inch maps were first published in the immediate post-war years and have since been extensively revised, though not all sheets have been brought up to date. Further revision of this series will be restricted to major changes pending gradual replacement by a new series.
§ Mr. Jackson
I thank my hon. Friend for that reply. Will he give an assurance that these provisions will be coordinated with local authority annual or quinquennial reviews of footpaths? As he knows, it is the intention to publish 2½inch and 1 inch footpath maps and it would be helpful if there were to be co-ordination between the Ordnance Survey and the local authorities.
§ Mr. Skeffington
I do not know whether I could go so far as to say that it would be co-ordinated with each quinquennial review, because it depends on the amount of change and the demand for the particular sheet of the Survey. However, the Survey is always in close touch with local authorities and all significant changes are incorporated, not only in the major revisions, but also in the reprinting which takes place usually between revisions.
