Topographic maps have proved to be effective, legitimate, and convincing media to demonstrate to external agencies how the community value, understands interacts with its traditional lands and immediate space. From cave/wall paintings, ancient maps of Babylon and Greek philosophers, through the Age of Exploration, and on into the 21st century, people have created and used maps as the essential tools to help them define, explain and navigate their way through the world. Topographic maps represent features on the earth's surface through symbols and labels; separate colors distinguish the main classes of map features. But at the Tepi campus the main problem; there is no clear topographic map prepared to explain land features and slopes of up and down of land. So, this makes that information gap on a topographic map scale, the purpose of the map. The main objective of this study was to describe the preparation of a topographic map using the application of GIS and GPS techniques.
This study specifically focuses on the preparation of a topographic map; identify the information of contour and the triangulation irregular network of the enclosed area. The method used for this study was to collect field data of each feature of Tepi campus using GPS instrument and downloading in the office the collected data.Some of the surveying instruments and software used to prepare this topographic map was GPS instrument (Trimble R8 receiver), GPS, GIS, and AutoCAD. After the field data was downloaded; the researcher was given a scientific name for each feature and digitizes the futures using GIS software.
The result of this study where including a prepared topographic map of Tepi campus, the slope analyzed by surfer 32 software, and triangulation irregular networkprepared by GIS software. The prepared topographic map of Tepi campus was shows both the natural and manmade features. Such as; forests, rivers, roads, fences, buildings, and vehicle parks.
Finally, prepared a topographic map of Tepi campus, triangulation irregular network, surface analysis, and the slope that identify elevations all features of the study area..
