Geophysical survey methods provide cost-effective means for the acquisition of archaeological information relevant to a number of domains:

management and planning maps of archaeological sites can be created that document their basic subsurface structure and the layout of features;

primary data for settlement pattern research and analysis can be obtained when details of a site are clearly mapped;

the placement of expensive excavations and testing programs can be guided to features of potentially greater interest, producing large cost savings in site explorations;

geophysical methods are non-destructive, preserving the resource for future generations. Non-invasive examination of culturally sensitive burial, sacred, or ceremonial sites can be achieved.
