Transit Theodolite: A theodolite is called a transit theodolite when its telescope can be transited i.e revolved through a complete revolution about its horizontal axis in the vertical plane, whereas in a-Non-Transit type, the telescope cannot be transited. The line connecting any two points is a straight line and the angles of polygons are plane angles. This is a precision tool well suited for both home improvement use and large-scale surveyor jobs.

If you need to level ground, then a transit level is necessary for identifying contours in the land and surface area that will be used for construction. They are used to establish a reference line, but they are also used to provide readings of angles in precise measurements. In traverse surveying the length and direction of any survey line can be measured with any direction measuring instrument such as compass,theodolite and for measuring length chain or tape can be used.The traverse survey are again classified into chain .

Surveyors created the National Geodetic Vertical Datum of 1929 (NGVD 29, the predecessor to NAVD 88), by calculating the average height of the sea at all stages of the tide at 26 tidal stations over 19 years Surveyors extended the control network inland using a surveying technique calledleveling. Micro-meter . This builder’s level is accurate to a ¼” per every 100 feet, and its 360-degree horizontal circle with Vernier scale produces precise measurements of horizontal or level angles. The two pieces of survey equipment that surveyors use most are a transit level and a theodolite are used by the surveyor to measure both horizontal and vertical angles. These types of leveling can be used to alter the grade of a job site or to detail the existing grade of a hill. Systematic Errors Systematic errors are caused by the surveying equipment, observation methods, and certain environmental factors.
