Abstract
AN extended scheme of aerial mapping in the southern States is planned under the United States Geological Survey in co-operation with the Shore and Geodetic Survey, the Census Bureau and other Federal bodies. The area to be covered, according to a report issued by Science Service, of Washington, D.C., is 40,000 square miles, selected from agencies in the States of Alabama, Arizona, Arkansas, California, Georgia, Louisiana, Mississippi, New Mexico, South Carolina, Texas and the District of Columbia. The maps will be used primarily in connexion with the agricultural census to be made in November next, but will have a permanent use as State records and for other purposes. The need for a more systematic land survey is indicated by the fact that air reconnaissances have already revealed the existence of vacant farms and waste lands not under cultivation hitherto unrecorded and consequently in some instances escaping taxation. There may be an extension of the scheme later to cover 1,000,000 square miles. As at present planned, it will take seventy days to complete at a cost of 650,000 dollars. The aeroplanes will have the cooperation of link-men on the ground under observation, and altogether 500 engineers with 1,500 assistants will be employed. The scheme is part of the programme of the Civil Works Administration for the relief of unemployment.
