| After
archaeologists find a site they want to examine, they do a
survey. First, they walk as a group across the site in a straight
line, looking for artifacts on the ground. |
|
 |
They
flag any objects they find and take their exact location using
a transit or a total station. These measurements help archaeologists
to make maps of the site itself and the places where artifacts
are found on the ground. |

A total station allows archaeologists
to take precise
measurements . . .
|

and automatically records them in a computer
in order to create maps later on.
