Best Answer

When surveying on the civil engineering or construction site it is often necessary to find the coordinates of new control points or points of detail. This is relatively simple if both the existing and the new point are accessible but often one of them is not and so other techniques are required. For example the new or existing survey points may be targets on walls, points on high buildings or points on land to which access is denied. When the existing points are accessible but the new point is not then the survey needs to employ an intersection technique. When the existing points are not accessible but the new point is then the survey needs to employ a resection technique.
