Abstract : This report covers an investigation to determine the feasibility of producing, from aerial negatives, duplicates that are as satisfactory for all mapping purposes as the originals; to ascertain the minimum requirements for duplicate aerial negatives suitable for all mapping purposes; and to furnish ideas or suggestions which could be employed to meet the minimum requirements. The report concludes that the preparation of duplicate negatives which are as satisfactory for all mapping purposes as the originals is not feasible with existing photographic materials; but that the preparation of such negatives is feasible if suitable photographic emulsion and processing techniques can be developed.
