A topographical map details the land surface features of a particular area. There are four main types of land characteristics shown on a topography map. Landforms on a topographical map are features such as mountains, valleys, ridges, peaks, and saddles. The watercourses shown are areas like rivers, streams, lakes, swamps, and reservoirs. Vegetation displayed on a topographical map is often that of parks, farmland, plains, and orchards. Humanmade features such as buildings, roads, trails, boundaries, and railway lines can also be shown on a topographical map.
Topographical maps are traditionally delineated as two-dimensional planes and can now be made into three-dimensional maps thanks to modern technology. The data collected from the older two-dimensional maps along with photogrammetry and 3D printing technology allow for the creation of highly-accurate three-dimensional representations of land surfaces.
A three-dimensional topography map is easier to read than a two-dimensional topographical map. The 2D topography maps show elevations as lines on a sheet of paper, whereas a 3D topography map shows the elevations with raised dimension. Novice cartologists can plan mountain trail routes by visually following the path and seeing the route interaction with terrain elevations.
