Topography describes surface features and shapes on maps and is a field of planetary science of the Earth that includes additional astronomical objects such as asteroids, planets and moons. Topography also provides local details of an area in general, such as artificial features, culture, local history, vegetation and relief. In some instances maps with elevation contours have made these types of maps synonymous with relief. However, topography in the older sense is still used to study places and areas in major countries like Australia and Europe. Topography maps have three dimensional features of the recording of terrain or relief and identify specific landforms which are at times termed as geomorphometry. In today’s times these maps provide generations of data online in the form of eTopography Maps.
Topography maps include graphic layouts of the land in any particular area by including contour lines, relief shading, hypsometric tints and several other valuable techniques, which is why topographic maps now have multiple uses. Making use of these highly detailed topography maps for earth sciences, mining, recreational, earth based assignments, geographic disciplines, orienteering or hiking is a standard requirement. The use of conventional symbols and signs represent various features shown on topography maps. For instance roads are indicated by colours, which are explained separately or in the margin of the map. Many people commonly refer to these maps as topo or contour maps. They are also referred to as quadrangles or topo quads when strictly organized by a 7.5 minute grid.
