This is a report on a meeting entitled "Multiple Representations", held in Buffalo, New York, 18-21 February, 1989. The purpose of Research Initiative 3 of the NCGIA was to enumerate impedimentsassociated with digital representation of geographic features, and particularlythose impediments associated with problems of producing multiple graphicaldepictions from a single digital database.

The goal of the Specialist Meeting was to bring together researchers from the disciplines of cartography, geographical analysis, computational vision, and spatial database management with representatives from federalmapping agencies and private mapping houses. For a period of four days, thegroup discussed technological and conceptual impediments associated withmultiple representations, and defined research goals that might be addressedto alleviate existing problems.
