A differential survey allows you to survey an area of land rather than just points within a line.

Back

True

Front

Foresights on a survey are always taken after backsights.

Back

True

Front

Most surveying elevations start at 100 feet to avoid negative numbers when measuring slope.

Back

False

Front

A station in a survey may have a foresight and no backsight.

Back

True

Front

To get the station elevation, subtract the backsight from the height of instrument.

Back

False

Front

When completing field notes, column headings are not necessary, as all surveyors follow the same format.

Back

False

Front

Is it acceptable to take measurements in the field and make the field notes when returning to the office?

Back

False

Front

To calculate the height of instrument, add the backsight measurement to the elevation.

Back

True

Front

The longer the distance of the traverse, the greater the allowable error.

Back

True

Front

If the allowable error calculated is less than the difference between the beginning and ending benchmark elevations, is the survey acceptable?
