The Nature of Geographic Information

2. Context


This section sets a context for two case studies that follow. First, I will briefly define low-level radioactive waste (LLRW). Then I discuss the legislation that mandated construction of a dozen or more regional LLRW disposal facilities in the U.S. Finally, I will reflect briefly on how the capability of geographic information systems to integrate multiple data "layers" is useful for siting problems like the ones posed by LLRW.
