JANUARY/FEBRUARY 1979

GAZETTE

In the past it was considered that the publication of a map was a once only operation not to be updated until some suitable time in the future when a complete resurvey or revision would again take place. In the interim no main- tenance of the sheet was carried out. The continuous revision system generally attempts to ensure that the pace of map revision will keep abreast of the change taking place. Surveyors have been appointed to areas that have been updated to keep the maps revised and copies of these revisions can be purchased. The Ordnance Survey will also, on request, carry out special revisions for customers in areas under continuous revision. In addition, mapping which is not yet published but is at some stage of pre- publication can be purchásed. Areas at present under continuous revision are the counties of Dublin, Carlow, Kildare, Meath and Laois. Continuous revision information and pre-publication information is also available for Cork City and Gal way City. Requests for such information should be sent to the Ordnance Survey, Phoenix Park, Dublin. The Ordnance Survey also offers a number of other services which can be of assistance, to solicitors. They include the supply of enlargements or reductions of published large scale maps, continuous revision documents and pre-publication data. These are normally supplied on transparent plastic material with paper copies, dyelines or photostats also available. Composite transparencies may also be obtained. Delivery times and quality depend on the nature of the require- ment and on the quality of the original material. The Surevy can undertake map mounting on board or cloth for single or composite maps. Other services include heat- sealing and edge-binding of maps. Details of mapping control for both height and planimetric positioning are available and approximate National Grid co-ordinates for all County Series maps and can be supplied. Copyright and Pricing No Ordnance Survey publications may be reproduced using mechanical, electronic, photocopying or other methods without prior permission of the Director of the Ordnance Survey. State copyright subsists on O.S. maps, transparencies of maps and field documents. Speical licences to cover all forms of copying are obtainable from the Ordnance Survey and sufficient flexibility exists to meet the particular needs of those who have a need to copy maps. Unauthorised copying in many cases is due tó innocence, but as usage in maps and copying is increasing the Ordnance Survey is progressively taking a much more positive approach in relation to the infringement of copy- right. There are two reasons for the more strict attitude:- (a) The first and most obvious is the loss in revenue; (b) The less obvious reason is that it provides the Ordnance Survey with information regarding map usage and the statistical data to prove the requirement for maps in the economy of the country. Concern has been expressed about the cost of maps and related documents. The Ordnance Survey is anxious to keep these costs to a minimum but there is no short cut to good mapping and it is not possible to produce "a bit of a survey" on the cheap. So if adequate mapping is to be provided it will have to be paid for by the user and the taxpayer or by a combination of both.

The cost of older maps has also been raised. It has been suggested that these are too expensive. The cost of storing and particularly reproducing existing mapping is very considerable. Reprints of older map sheets have to be reproduced from paper manuscripts and these, due to their age and to the material on which they are printed, are far from ideal for reproduction. They are distorted and the quality of the detail has deteriorated with the result that when the need to reproduce arises, con- siderable work has to be done on them before an adequate printing can be achieved. The cost of reproduction and storing of existing mapping is therefore considerable and as the number of copies produced is small the unit cost is high.
