What is Topographic map?

It is a map made in very great detail and as accurate as possible to display earth surface and elevation from sea level (cartographers used triangulation pillars to map land and mountains out, but are no longer required as they use different more advanced technologies now. Triangulation pillars worked as landmarks and you can still found them around the country). There are 2 types of topographic maps mostly used in UK: Explorer and Land ranger – both created by Ordnance Survey. They have differences like markings and marking colours, but are pretty much the same. If you know how to read Topographic maps and contour lines you could easily identify forests, lakes, rivers, mountains, slopes and other features that are on the ground. Contour lines measure from sea level in meters and are 10 metres apart of each other. You can find different scales in typographic maps which is a smaller representation of land in a map e.g. 1:250 000. These kinds of maps are mostly used for architecture, earth sciences, geographic planning, mining and hiking.
