摘要：Exchange of data between different software/hardware systems has traditionally involved porting data directly fromSystem A to System B. With large numbers of systems, this tradition has created very large numbers of unidirectionaltranslators, which are often incomplete (or even error-inducing) and are difficult to maintain and use well. One mustsometimes pass data through several intermediate steps between System A and System B. Two alternative systems are(1) to develop a broad-based SystemA-SystemB translator with a data description language encompassing many formsof data (such as the National Geophysical Data Center's FreeForm), and (2) to develop a comprehensive transferstandard and format system, thus requiring systems to have only "IN" and "OUT" translators into the common formatsystem (such as the Spatial Data Transfer Standard - SDTS). We offer suggestions for improving the success of yourtransfers between systems. The new SDTS Point Profile offers an opportunity to facilitate porting point data from database management systems into geographic information systems.
