The use of interpolation in archaeology is becoming common. As archaeologists incorporate geographic information systems (GIS) and computer mapping programs into their research, questions of interpolation become fundamental considerations in the representation and manipulation of topographic data. To date, however, few archaeologists have dealt with these questions. Uncritical use of interpolation algorithms can result in unrealistic representations of the landscape in a mapping program or can result in an inaccurate digital elevation model (DEM) used in a GIS. This, in turn, can lead to an ineffective predictive model of site location. By carefully selecting an interpolation algorithm that is well suited to the data, statistical pitfalls and wasted effort can be avoided.
