3)The accompanying tabulation gives elevations of points over the area 20m by 20m city lot.The elevations were obtained by the checkerboard method using 10-m squares. Requirements: a)Plot the contours using a horizontal scale of 6cm=10m and a contour interval of 1 meter. b)Use short-sized bond paper.All corner designations and corresponding elevations must be indicated, including all vertical and horizontal lines. c)Indicate the following Index contours:880,885,890 & 895.The thickness of the index contours must be drawn about twice the thickness of intermediate contours. d)Show solutions in interpolations. EE A 878.80m 882.50m 883.50m B 883.20m 885.90m 893.70m C 882.80m 888.60m 891.80m

Control Survey and Geodetic reductions

Control surveys or survey controls are used to establish reference points as a basis for various construction activities. Vertical and horizontal control points are to be established in a control survey to increase accuracy. After establishing the control points, all other types of surveys such as topographic, right-of-way, aerial mapping, construction layout, boundary surveys, and utility mapping can be worked upon so that control networks can be formed. The place from which the observations are made is called a survey station.
