The control point surveying or table surveying are also quite effective in making a topographic map within a local survey. It is created by rotating an ellipse around the shorter polar axis to match the Earth's actual shape. Closed traverses yield adequate accuracy for property boundary surveys, provided that an established control point is nearby. Triangulation is a surveying method that measures the angles in a triangle formed by three survey control points. There is no angle measurement are used and direction of the lines are fined entirely by linear measurements. Get all your industrial equipment from Ejawda. Land surveyors measure horizontal positions in geographic or plane coordinate systems relative to previously surveyed positions called control points, most of which are indicated physically in the world with a metal benchmark that fixes the location and, as shown here, may also indicate elevation about mean sea level (Figure 5.10).
