Abstract:  This report describes the results of NCGIA Initiative 3 on Multiple Representations. It begins with a discussion of objectives and the process of developing a research agenda. Each of the major research activities is discussed. The initiative was active during the period 1988-1990. Since that time, research activities have continued, and include research following the original agenda as well as off-shoot research topics that have been subsequently refined to formalize NCGIA Research Initiative 8, Formalizing Cartographic Knowledge. These transitional research activities will be briefly presented. OVERVIEW The scope of concern in the use of the term "Multiple Representations" refers to changes in geometric and topological structure of a digital object that may occur with the changing resolution at which that object is encoded for computer storage, analysis and depiction. Cartographic and digital data arguably provide only a sample of the geographic features they are intended to represe...
