Abstract
THE urgent necessity for modern town plans required under the Town Planning Act has raised the possibility of meeting the demand by aerial survey. In most cases, less than two years remain for the completion of these plans. The Ordnance Survey at its existing strength cannot; hope to meet this demand. A scheme outlined in the Times of May 5, however, promises to meet the situation, and the Ordnance Survey has promised its co-operation if local authorities make immediate revisions by air survey. The scheme would admit of the 16,000,000 acres of town planning areas in England and Wales being covered within two years. The country would be divided into sixteen units, of which eight would be photographed concurrently. On the reasonable assumption that 30 days in the year would be suitable for vertical photography, the work could be done in the two years available. Local authorities would be supplied with prints on a scale of 1: 5000 and a set of transparencies on the same scale as the Ordnance sheets. The originators of the method are Messrs. H. Hemming, Ltd., and Economic Air Surveys, Ltd. The fully revised Ordnance sheets would follow later.
