Abstract

Topographic survey must have the highest priority in all countries, whether developed or developing. Topographic Survey is a field exercise and is granted the student the opportunity to put in practice what they learnt theoretically. This in this regard we have carried out the topographic survey of Ruhengeri institute of higher education during three weeks. The research had an objective to produce a topographic map of Ruhengeri institute of higher education, identifying and mapping the contours and existing features of Ruhengeri institute of higher education such as buildings, streets, trees, etc. This research was done with some methods such as closed loop traverse. This type of closed traverse begins at a point of known control, moves through the various required unknown points, and returns to the same point. Two groups, one for the INES3 to INES1, other one for the INES4 to INES1 participated in this research, each group had total station. The establishment of control networks is the most fundamental operation in the surveying of large or small areas of land. Control networks comprise a series of points or positions which are spatially located for the purpose of topographic surveying, for the control of supplementary points, or dimensional control on site. The results show the topographic map of Ruhengeri Institute of Higher Education with their contours, features (streets, manholes, trees, buildings….), this map is at scale of 1/40 on the paper. It has 1st order contours in blue color and 2nd order contours in red color. The interval of 1st order contours is one and 2nd order contours is 0.5 but is shown in the legend. The Ruhengeri institute of higher education is on low altitude where there are contours apart each other’s, and it is on high altitude where there are the contours close each other’s.
