Plane surveying:To determine the boundaries, area, or elevations of (land or structures on the earth's surface) by means of measuring angles and distances, using the techniques of geometry and trigonometry.
Geodetic surveying:Remote sensing, mapping and charting depending on plane surveying of fixed reference points, like monuments, longitude and latitude coordinates; magnetic effects, and relative velocity of Earth points to each other.

plane surveying makes the simplifying assumption that the earth is flat. this will work for projects that are less than a mile or two in scope. geodetic requires knowellege of the earth's actual shape. the 1866 Clarke sphereoid was really the first try at this. the 1927 datum was widely used in the US and is the basis for most printed topo maps. With satellite gps, we now use 1983 datum.
