and scale, delivering vector data to users, standards, and spatial statistics and analysis.
This chapter explores the role of the USGS in contributing to new knowledge in the areas of cartography and GIScience, and delineates the priority research items. The National Map is expected to be the flagship product of the Geography Discipline in the next decade. However the accomplishment of this worthy goal is not assured with present knowledge. Further basic GIScience research is needed to make the product a reality. The USGS should undertake additional GIScience research towards the development of The National Map and of a more general nature, if it is to fulfill its vision and mission.
