COMMUNICATIONS In accordance with the statement of • the Committee on Organization for the Congress, communications may be written "in the language of the author. Everybody will understand t h a t for practical reasons this has to b e restricted to the languages

used in " P h o t o g r a m m e t r i a " . As f a r as the langTaages are not English or French, the author has to provide an abstract both in English and in F r e n c h not exceeding 400 words, which has to be sent to the President of the Technical Commissions

93 most directly concerned. These abstracts will be printed in the report of his Commission. The publication of these abstracts belongs to the task of the country charged with the responsibility for a certain Technical Commission. The communications which the authors w a n t to be published and distributed at the Congress have to be sent in advance in 2000 copies in size 210 X 290 mm (printed p a r t 126 X 212 mm), the size of the International Archives of Photog r a m m e t r y in which these publications will be inserted. These 2000 copies have to be sent to the official mailing address of the Congress: Mr. L. Ray Smart, P r o g r a m Director I.S.P., U.S. Geological Survey Trimetrogon Section, W A S H I N G T O N 25 D.C. The editors of " P h o t o g r a m m e t r i a " have kindly offered to publish in advance papers to be delivered and discussed at the Congress, particularly those papers which might be difficult to understand fully when presented orally. Reprints of such articles can be obtained against payment f r o m the Publishers, N.V. Uitgeverij " A r g u s " , Singel 26, AMSTER-

DAM C. Netherlands. They can be used either for distribution at the Congress and/or for insertion in the International Archives. If desired these reprints can be made to the same size of the International Archives as mentioned above. It is recommended t h a t prepared discussions of papers b'e solicited by their authors from among photogrammetrists in other organizations or countries whom they know to be interested. Notice of the desire to present a prepared discussion of a communication shall be furnished to the President of the Commission concerned not later than the opening day of the Congress. The Presidents of the several Commissions are empowered to decide the order and time allowed for each communication and formal discussion. They are expected to give precedence to communications prepared in accordance with the foregoing requirements with the possible exception of important developments occurring between 1 April 1952 and the opening of the Congress. Authors shall specify the size of projection slides or films, if any ,that will be used in the presentation of their papers in a letter to the P r o g r a m Director not later than 15 June 1952 in order to insure suitable projection facilities.

T H E T E C H N I C A L COMMISSIONS The main technical work of the Congress will be accomplished by the seven Technical Commissions. Each Technical Commission will hold three sessions covering: (1) work accomplished and developments since 1948 i (2) improved techniques, standard tests, special communicati-

ons; (3) future possibilities and research. Because of the wide general interest in the rapid developments of each field, the technical sessions of the commissions will not overlap. Short concurrent sessions for resolutions before the final plenary session are scheduled.

THE TECHNICAL COMMISSIONS AND THEIR OFFICERS See Photogrammetria 1949/50 no. 3 T E N T A T I V E PROGRAM The tentative program for the VII Congress contemplates registration and a meeting of the International Council and National Society Presidents on 3 September, with the 1st Plenary Session, Opening of the Exposition and s t a r t of the sessions of the Technical Commissions on 4 September 1952. The Technical Commission sessions will continue each working" day until the final P l e n a r y Session on the afternoon of 13 September 1952. The meetings of the various commissions are 7

being scheduled so as not to overlap. If circumstances permit the Congress will adjourn to W r i g h t Field, Dayton, Ohio, for a two day meeting on 15 and 16 September. This will include an inspection of the Photographic Laboratories and some unclassified research project~ as well as technical papers on research and military applications of photogrammetry. A program of sightseeing, shopping and social activities is being arranged for

94 ladies. There will be a t o u r of p o i n t s of general interest in the vicinity of Washington on Sunday 7 September. Several technical tours to organizations using p h o t o g r a m m e t r y in the vicinity of Washington are being a r r a n g e d during the Congress. A cocktail p a r t y on the evening of 4 September and a dinner and dance on 12 September are scheduled. The Exposition will feature exhibits of photo interpretation as well as specimens of the latest maps and applications of photogrammetry. On exhibit also will be a number of new wide angle lenses and photographs of g r e a t interest to photogrammetrists. Manufacturers have arranged to display new models of the leading plotting instruments and a number of new instruments developed since the 1948

Congress. A separate publication with complete information r e g a r d i n g exhibit space, facilities and a r r a n g e m e n t s is being distributed to the National Societies, Commissions and others likely to be interested. Copies of the exhibit invitation may be obtained by writing tot the Prog r a m Director. The t e m p e r a t u r e in Washington and Dayton during the first two weeks of September averages 250-28 ° C (760-82 ° F ) . Occasionally there are very w a r m spells with maximum t e m p e r a t u r e of 30°-35 ° C (850-95 ° F ) . The Shoreham Hotel is airconditioned so the sessions of the Congress will not be too uncomfortable in any event. During September 1951 the highest t e m p e r a t u r e was 32 ° C (90 ° F).

LIVING ACCOMMODATIONS If rooms are desired at the Shoreham or other nearby hotels, reservations should be made as f a r in advance as practicable. Late reservations may not be possible. Single rooms at the Shoreham will cost approximately $6.5.0 to $8.00 per day and double rooms $8.50 to $11.00 per day. Other hotels in the vicinity of the Shoreham have single rooms at $5.00 per day and double rooms at $6.00 to $8.00 per day. Cots are available at an additional daily cost of $1.50 each. Meals are available in r e s t a u r a n t s in the hotels or nearby a t additional cost.

Rooms will be available in college dormitories, the International House and clean rooming houses. Such accommodations will cost about $1.50 to $2.00 per person per day. Meals in cafeterias and cheaper r e s t a u r a n t s cost $0.35 to $1.50 with a reasonably adequate diet costing about $2.00 per day. The least expensive travel to the United States is by scheduled freight steamers having accommodations for a limited number of passengers. Reservations on such ships must be made a long time in advance.

REGISTRATION No professional qualifications or official appointments are required to register for the Congress. The registration fee for all the activities of the VII Congress is $15.00. This includes the mailing of advance prints of reports and abstracts of communications, and attendance at all functions, tours, p a r t y and banquet. It does not include transportation to Dayton, Ohio. It is

expected t h a t arrangements for free t r a n s p o r t a t i o n (but not subsistence) will be made for members from other countries from Washington to Dayton. P a y m e n t of $2.00 will be requested by 15 June 1952 to insure advance mailing of reports and abstracts. The balance may be paid on registration at Washington.

P U B L I C A T I O N OF A WORLD R E G I S T E R OF P H O T O G R A M M E T R I S T S The International Council is considering the publication of a World Directory of Photogrammetrists. All those who are qualified to direct or perform some photogrammetric or photo interpretation technique are requested to fill out form, whether they expect to be able to attend

the Congress or not. Forms may be obtained through your National Society o1' the P r o g r a m Director, I.S.P. Institutions, industrial organizations, and other establishments are requested to furnish complete details of their activities and products for use in the register.
