Problems of Cartographic Design in Geographic Information Systems for Transportation

R. Gordon Kennedy


Geographic information systems for transportation (GIS-T) seek to integrate the geospatial approach of GIS and the tabular approach of conventional transportation analysis. GIS-T deals with such topics as network analysis, linear reference systems, travel demand modeling, and intelligent transportation systems. Conventional cartographic treatment of route features is reviewed in the context of the mapping challenges introduced by GIS-T. Problems in the visualization of complex linear data are identified and examined as cartographic design issues. Cartographic requirements are specified for mapping route-based data and basic design issues are identified. The representation of complex route-based data layers is posed as an undeveloped specialty of cartographic design. Some of the issues involved in developing such fundamental principles are summarized and potential avenues of research are suggested.
