Geographic information (GI) use spans the mundane activities of everyday life to the grandest scientific endeavors. Developing an increased understanding of GI access and use is possible using approaches that are grounded in human information seeking behavior. Furthermore, making GI more accessible, discoverable, and usable to various stakeholders requires an assessment of users’ information needs and crafting services to facilitate GI access and use. This chapter will provide some background, terminology, and theory of human information seeking behavior. Instrumental to GI use are geographic information systems (GIS). The chapter concludes with a discussion of GIS software options and site license management approaches.
