There is no one approach to learn the basics of topography. However, you must always have proper knowledge about geography to learn topography. If your concept of geography is outstanding, it will be easier for you to understand the topographic maps. Once you understand the process of deriving the 4 or 6 letter coordinates from a map, you can easily detect all minute things on the map. Apart from deriving the coordinates, you must check all the marks from the index properly to comfortably study a map. In advanced stages, you can make topographic maps on your own. Taking the topography and geography courses from Vedantu can help you understand the concepts easily.
