Page:Glossary of NPIC Terminology (1965).pdf/3

Rh

This glossary contains standardized definitions for terms frequently used in NPIC publications. It is intended as a guide for NPIC personnel and as an explanation for the consumer of NPIC publications.

Entries in this glossary are arranged alphabetically and, where applicable, are followed by parentheses containing the appropriate abbreviation or by brackets containing the part of speech to which the definition applies. Parentheses which appear after definitions contain explanatory notes, such as a cross reference or an indication of the general field in which the term is used. When the same term has more than one meaning, the different definitions will appear in numbered sequence under the general term.

Definitions provided in this glossary are those which have a specific or specialized application in the field of photographic interpretation, and terms which are adequately defined in standard dictionaries have not been included. The present listing, however, should not be considered complete since work is continuing on the selection and definition of additional terms which will be included in future editions. Users of this glossary are invited to suggest the addition of terms which need defining or to comment on the definitions provided.
