It is called altimetry to the branch of the topography specialized in height measurement . It should be remembered that topography is the discipline that is responsible for the detailed description of surfaces.

Also known as hypsometry , altimetry encompasses various processes, methodologies and techniques for the determination and representation of the height of a point, taking into account a certain reference plane. In this way, altimetry enables the relief representation .

The instrument that allows to know the distance in height that exists between a point and the reference plane is known as altimeter . Thanks to this instrument, you can discover what height there is a point with respect to sea level.

Altimetry, thus, is present in the aviation . The altimeter is among the most important flight instruments, as it constantly measures how high an aircraft flies. To offer this data, the tool Calculate the distance that exists, vertically, between the aircraft and sea level.

This makes altimetry a key to aviation since the flight routes they are organized according to the altitude . An aircraft, therefore, has to fly at a certain height according to the route assigned to the pilot; This data comes from the altimeter.

In addition to all of the above, it is worth knowing other interesting information such as these:
-In altimetry plays a fundamental role what is known as leveling. This is an operation that aims to discover the level distances that exist between the various points of the same terrain. For this, data such as the reference surface, the elevation, the level line, the altitude, the average sea level will be used
-The altimetry and this leveling will play a fundamental role in the realization of a myriad of projects, such as the drainage of populations, the construction of roads, the implementation of railways, the implementation of channels or viaducts , the elevation of bridges of considerable size ...

Miscellaneous sports , like skydiving, mountaineering and skiing, also appeal to altimetry. In these cases, the altimeter lets you know what type of unevenness the athlete is going through and how his ascent or descent is developing.

Moreover, in cycling, altimetry also plays a fundamental role since it allows since the organizer of a race can determine the ascents that the race will have until the runner can know at all times which are the hardest sections that will require more effort of the whole test.

Of course, it goes without saying that it is also very useful for athletes who practice pedestrism. Thus, when athletes train for the competition, thanks to altimetry data, they can prepare it much better. Knowing that information will help them know when they should make more effort, what will be the heart rate they can have ...
