Main stations are the ends of the lines which command the Boundary of the survey, and the lines joining the main stations are called main Survey or Chain lines. Note these are the coordinates for the imaginary station that was created earlier.
Temporary Bench Mark (TBM) A moveable object that has a known height above a pre-defined level. There are two main types of stations namely Main station and Subsidiary or Tie station.
A two-pole chain is twice the length of a rod, or 16.5 feet. Place the survey illustration on a large flat surface, as property surveys can be quite large. Change points are points of measurement which are used to carry the measurements forward in a run.
The illustration is basically a map of the area surveyed. The survey party installs control stations at regular intervals. This is the sort of information that will be recorded again in a static control survey to show the station that has been occupied, show a sketch of where it is located . A land survey can be expensive.
"Coordinate" > "Station Orientation" > "Station Coordinate" Set the target height to the measured height of the mirror target. counterclockwise (angle to the left). the centre of the Total Station above the survey point and that needs to be measured each time you set up the Total Station on a survey point.
Breakdown of closed-ended questions. Keep the written report on hand for easy reference. Vertical Angle The vertical angle is measure relative to the local vertical ( plumb ) direction. In this post, we are going to discuss about the bearing in surveying and its designation. Bisect station A with the help of the lower clamp and make the vernier to read zero degrees.
How To Determine The Coordinates Of Directional Survey stations. Still holding the survey gun, check that the instrument is securely fastened.
Introduction. Depending on how long it takes for light to reflect, a surveyor can determine how far away certain objects are. Multiple surveys can be performed at one set up location. Turn the total station until the horizontal circle reads zero. It should also be noted that an over-the-air station and an Internet-streaming station 14.
Second, The measured depth (AHD) of the survey station. Fulfills your job duties Professionalism to your position Interpret the project information Answer questions from public, contractor and governing body Monitor material quantities Act as a liaison between the contractor and the governing body and the public Explain and obtain Right of Way from landowners Monitor progress Quick collection of information. If you turned around you would be facing South and would be 180 degrees South of North. Angles and Directions Construction Plans are 2D Drawings.

The purpose of directional survey is to: Determine the exact bottomhole location to monitor reservoir performance. The property survey consists of two parts: the illustration and the written report. A station is expressed as the 100' station followed by the remaining horizontal distance, ex. Right-of-Way - the limits of ownership of the Railroad's property. By measuring the prism's position and knowing the precise angle and distance to that prism, the total station calculates the prism's location or coordinates. From setting building corners to sighting utility lines, this sophisticated instrument provides surveyors with an important time-saving tool. Students who successfully complete Chapter 5 should be able to: identify and define the key aspects of data quality, including resolution, precision, and accuracy; list and explain the procedures land surveyors use to produce positional data, including traversing, triangulation, and trilateration; calculate plane coordinates by open .
