NECESSITY OF DATA INTERCHANGE STANDARDS The need to transfer spatial data between noncommunicating systems is becoming increas ingly important. The concerns for common data formats and geocoding conventions cut across all topics of spatial data handling. Currently, it is difficult and inefficient for diverse users to use a given set of data. At least five major forces are causing concern about incompatibility: (1) increasing amounts of spatial data are being generated and must be stored, cataloged, and retrieved, (2) there is rapid progress and expansion in the area of spatial data processing, (3) increasing amounts of related and useful data are being obtained in digital form, (4) increasing sophistication in the ability to register digital images with maps and to analyze multiple sets of data is resulting in a call for more digital data, and (5) much of the map automation effort may be duplicative and redundant (Digital Cartographic Data Standards [DCDS] Task Force, 1988). A spatial transfer standard offers several advantages to users of spatial information: (1) it provides a systematic and comprehensive set of primitive and simple cartographic objects from which digital cartographic feature representations can be built, (2) it allows the transfer of digital spatial information between noncompatible systems while preserving the meaning of the information, (3) it supplies data quality information to users in order to evaluate the fitness of data for a particular use, (4) it offers the opportunity to share project costs by sharing data, (5) it results in lower overall cost for obtaining data and maintaining redundant data, and (6) it supports efforts to update data using multiple sources. Both the Federal Government and the academic community have been working for the last few years to develop a spatial data transfer standard that includes definitions of terminol ogy, a spatial data transfer specification, recommendations on reporting digital cartographic data quality, and topographic and hydrographic entity terms and definitions. Having such a standard in place will be a great benefit to the users of digital spatial data. SPATIAL DATA TRANSFER STANDARD History In 1980, the U.S. National Bureau of Standards (now the U.S. National Institute of Standards and Technology) signed a memorandum of understanding with the U.S. Geological Survey that resulted in the Survey assuming the leadership in developing, defining, and maintaining earth science data elements and their representation standards for use in U.S. Federal Government agencies. In 1982, a national committee composed of members from private industry, government, and academia began work on a digital cartographic data standard. This committee was formed under the auspices of the American Congress on Surveying and Mapping and was supported by a grant from the Geological Survey. Professor Harold Moellering of The Ohio State University headed the committee, which produced nine reports. Report 8, "A Draft Proposed Standard for Digital Cartographic Data," summarized the committee’s activities and work. In 1983, the Office of Management and Budget issued a memorandum establishing the Federal Interagency Coordinating Committee on Digital Cartography 625
