This chapter reviews several examples concerning the use of 3D GIS in support of field investigation. The subsections presented in this chapter provide a broad spectrum of possibilities for users to develop an analytic framework for generating new interpretative information as a result of a quantitative assessment using 3D surface/boundary models to document contexts and features retrieved during the excavation process.

By using examples from different projects, the text provides several considerations concerning the impact that 3D GIS is having on archaeological field practice. The chapter contains several informative BOXes designed to provide general instructions on how to implement and use the 3D models derived from 3D recording techniques in the 3D GIS environment. The last part of the text provides an example of how 3D GIS can be used to include the work of specialists operating in the field, identify new research methodologies and define new directions.
