definition of physical map

The physical map It is one of the types of maps that we can find most frequently and It is characterized by presenting represented the natural phenomena that occurred on the geology of a given terrain.

Map that cartographically represents the natural features of a terrain: mountains, plains, lakes ...

They are of great help in helping us understand their conformation.

Thus, the physical map will contain rivers, mountains and deserts that belong to a reduced area, such as a municipality, or may be the manifestation of a larger area, such is the case of a country or a continent.

Made to scale and respecting the measurements

They are made to scale and must always correspond to the measurements of the terrain in question, because the idea is that from it the user of the map can get an idea or calculate distances and surfaces with greater precision.

Using different colors to mark the references

Likewise, different colors are used and the intensity of them is played to, for example, indicate the altitude or depth of the terrain.

In this way, the sea water that surrounds a coast is usually indicated by the light blue color while that corresponding to an ocean is colored with a darker blue, because of course, the depth of the ocean is more pronounced with respect to the sea.

On the other hand, the dark green color is used to represent the depressions of the terrain, the normal green to the plains, the yellow is used to represent the plateaus, the orange warns the mountains present, the brown has to mark the mountains, the brown darker to the mountain ranges, and as we already pointed out, the blue and celestial colors are linked to the waters, the celestial marks rivers and lakes and the dark blue to the deepest oceans, as we have already said.

The task of making physical maps, as well as that of the rest of the types of cartographic representations, is in charge of professionals specialized in such a task who are known by the name of cartographers.

Meanwhile, cartography is the discipline that deals with studying and making maps.

The specialists consider the map as a super important informative document but also as an artistic work due to the great definition and art that some display in its design.

As we know, the map has been used for thousands of years and they are a fundamental tool when it comes to location, while this hyper-globalized world in which we are living has generated the need for more maps that provide more data.

An extremely useful, millenary instrument, which today is assisted by technology adding precision

It should be noted that the map is a very useful and important element for human beings and its advent, without a doubt, has been a solution when it comes to providing us with precise information about the territories that make up our planet.

And in recent years, the incorporation of technology in the field has given the field a lot of precision and variety in the data.

At the overwhelming and colossal rate with which new technologies advance, the design of maps has also advanced, which has become much simpler and simpler than a few centuries ago when there were not so many tools.

Currently, a lot of aerial and satellite photographs are used to be able to obtain a super precise image of a place and thus dump it on the map with the greatest possible precision.

In other words, as in the rest of the orders of life, technology not only makes many activities much simpler but also contributes to offering people more punctilious and implacable detail in terms of visualization and in this specific case that we are addressing, to the location.

But this type of map is not an exclusive use of geography but also genetics, when it began to be developed it began to make use of them to represent in an organized and precise way the genes and genetic markers that are present in a chromosome.
