§ Sir R. Russellasked the Minister of Housing and Local Government if he will estimate the cost of converting the production of Ordnance Survey maps to the metric system; and what will be the cost of replacing all the maps officially issued and published under the present system.
§ Mr. K. RobinsonIt has been decided that on new and revised Ordnance Survey maps at the 1/1,250 and 1/2,500 scales94W heights will be shown in metres and areas of parcels of land in hectares as well as acres; and that the six-inch map will be replaced by a 1/10,000 scale map with metric contours. The cost is estimated to be £3 million; work is being spread over the next fifteen years to minimise expenditure and manpower requirements. There are no proposals at present for the conversion of the smaller scale maps, and estimates of the cost of doing this are not available.
