Surveying is a science of making precise measurement of relative position of points and features sizes, shape and position of piece of land and present its physical on paper inform of a map; plan or section. The project grid leveling and contouring which is used to determine the spot height, contour and horizontal of position point in part of Kogi State Polytechnic, Main Campus Lokoja which was jointly executed in conformity with the school of Environmental Technology. The work was achieved by carrying out the following: (i) Coordinate of point (traversing) (ii) Girding (iii) Leveling (iv) Plotting of establish point and spot height. This project involves the use of three method of surveying and these are traversing was used to defined the project area into grid and leveling is to determine, the height of point grid. The project is aimed to provide a contour plan showing the elevation surface and contour of the area of the land cover. Meanwhile contouring is system of representation line on a plan or map joining of points of equal height on the earth surface or intersection of level surface within the area covered.
This project report is organized in four chapters, these reports address the various survey method and procedure adopted.
Instrument used for the field data, description of problem encountered and recommendation.
