15、iForeword (This foreword is not part of American National Standard ANSI NCITS 320-1998.)This document contains a specification of the Spatial Data Transfer Standard (SDTS), that will serve as a national spatial data transfer mechanism for the United States. As such it is designed to transfer a wide

16、variety of data structures that are used in the spatial sciences. These sciences include cartography, geography, geol-ogy, geographic information systems and many other neighboring sciences. SDTS consists of three primary parts: the first is the SDTS logical superstructure that pre-sents the organiz

17、ation and structure of the SDTS transfer mechanism; the second presents the definition of spatial features and attributes; and the third part presents the ISO 8211 data transfer implementation (i.e., encoding method). Work on a national spatial data transfer standard was begun by the National Commit

18、-tee for Digital Cartographic Data Standards in 1982 to develop a comprehensive set of data exchange standards for the profession. This work was funded by the U.S. Geological Survey through a grant to the American Congress on Surveying and Map-ping. In 1985, the Standards Working Group of the Federa

19、l Interagency Coordinating Committee on Digital Cartography also began work on spatial data exchange stan-dards. During 1987, the results of these parallel efforts were merged by the Digital Cartographic Data Standards Task Force into the proposed Digital Cartographic Data Standards, published as a

20、special issue of The American Cartographer in January 1988. Subsequent testing, modification, and refining of the results of these efforts were done by the Spatial Data Transfer Standard Technical Review Board. The end product of all of this effort is the standard presented here.This result represen

21、ts a collaborative effort by these groups to define a standard that will support work with cartographic and geographic data systems and facilitate spatial data transfer. It is designed to serve the spatial data transfer needs of the Federal agencies, especially the proposed National Spatial Data Inf

22、rastructure, and the work of State and local governmental entities, the private sector, and research organiza-tions. Requests for interpretation, suggestions for improvement or addenda, or defect reports are welcome. They should be sent to the National Committee for Information Technology Standards
