<span>3. </span><span>Route survey is a survey necessary for the location and construction of transportation or communication lines such as highways railroads, canals, transmission lines and pipe-lines.</span>
<span>4. </span><span>City surveying</span>
<span>5. </span><span>Before construction begins the exact position of the various parts of the dam </span><span>are fixed on the ground by using normal surveying methods. In choosing the site for a dam an engineer should study on a map the courses of all the rivers and streams in the area. </span><span>By reading the contours he should calculate the amount of water which can be stored by building a dam of a given height in a certain place.</span>
<span>6. </span><span>When deciding the route of a railway or road, the gradients, radii of curves, heights of embankments and depth of cutting can be calculated from data supplied by the surveyor</span>
