A topographic map serves as a two-dimensional depiction of the three-dimensional terrain. Unlike other maps, topographic maps uniquely capture both the horizontal and vertical dimensions of the landscape. Employing a combination of contour lines, colors, symbols, labels, and various graphical elements, they effectively illustrate the forms and positions of natural and manmade features such as mountains, forests, rivers, lakes, cities, roads, bridges, and more. By utilizing contour lines, a topographic map represents the diverse shapes, elevations, and slopes of the land. These lines connect points at identical heights above sea level, derived from vertical aerial photographs. The proximity of these contour lines indicates the steepness of the terrain, while the consistent height difference between adjacent lines remains uniform across the entire map. For the construction of any infrastructures or facilities in the area, an accurate and updated topographic map should be used in order to maintain the quality and accuracy of any activity using the topographic map. The topographic map was prepared using the different modern surveying instruments and techniques like Total station and GIS particularly in the college of natural science Area of Wallaga University. The Spatial data (Excel point data) of the area was collected using Total station and it was processed using the different software like AutoCAD, Eagle point, and ArcGIS to come up with the new updated and accurate topographic map. The contour map, built-up area, and Green area maps were also prepared in different layers for more information to be used as a reference in the construction of any new infrastructure in the area.
