What does altitude mean? Nature is full of highs and lows with different depths and, of course, different heights that some people like to measure these ups and downs vertically from the ground. Of course, it goes without saying that this measurement, in addition to quenching the curiosity, can show us a lot of information about the climate of the region as well as the living conditions in it.
We may all have used cell phone routers at least once to find our destination in two dimensions, but the important thing is that the same satellites that guide us in two dimensions are able to find the path we want. To measure your desired distance from sea level vertically. It should be noted that this distance from sea level should not be equated with altitude because the altitude is actually the distance from the ground to a certain point, while the distance from sea level is the height that an area has relative to the sea. Using a barometric pressure sensor and an internet connection, your cell phone can accurately measure your altitude. To get acquainted with how to do this and introduce the required applications in the continuation of this article, join us at Wironal.
The difference between altitude and altitude
Most people confuse the terms altitude and altitude, But there is a big difference between the two. The elevation is the vertical measurement of a specific surface or location up to sea level. For this reason, it can be said that the altitude is the same height from where you are to the average sea level, which is also known as zero level. On the other hand, height from the base level is generally used to determine the height that rises above a level (such as the ground level, building, etc.). Any height above ground level is known as the height from the base, and this type of height is usually recorded in special maps or diagrams.
For example, the height of a particular location can be 200 meters above average sea level. If you are exactly at an altitude of 1000 meters, the altitude is 1000 meters above sea level for you, but your altitude will be 800 meters above ground level (altitude above ground level). (Feet 800 = 200-1000)
How do cell phones measure altitude?
Your smartphones are able to measure altitude, and if you know the altitude of the area, you can estimate your exact altitude. The most important tools for accurately measuring altitude in smartphones are known as GNSS / GPS receivers. If your phone can find at least four satellites just above your head, you can get the exact height above sea level. Of course, keep in mind that connecting to satellites is not always the best, and although GPS often works well, there is always the possibility of relatively large errors.
For this reason, today’s mobile phones are often equipped with barometer pressure sensors (barometers). As the force of gravity pulls everything, including the atmosphere, toward the earth, the pressure decreases with increasing altitude; So measuring these changes will help your cell phone figure out how low or high you have gone.
Climate change can also affect the atmospheric pressure, which is why most altimeter apps try to get the most current pressure data from nearby meteorological stations, which allows the app to compare changes. . It is also effective to measure altitude based on a barometer without an internet connection, but you may have to adjust it manually.
1- Measuring altitude using the Compass App in iOS
The fastest way to measure altitude on iPhones is to use the Compass App, which is installed on all iPhones by default. If your phone can connect to a satellite and has a good internet connection, this app will show you the exact coordinates of the location and altitude.
Unfortunately, there is no such app as the default on Android, but there are several apps that will help you measure altitude and you can use them. But keep in mind that these apps are usually not very accurate.
2- My Altitude application for Android / IOS users
This app provides you with almost everything you need to measure altitude. Using My Altitude you will be able to have spatial coordinates, barometric pressure, boiling point, climate, altitude, and even information from the National Oceanic and Atmospheric Administration (NOAA) offline if downloaded. Currently, this application is available for download and download for Android and iOS users.
3- Altimeter & Altitude widget for Android users
This application is made by DS Software Boeh and can be installed only on Android phones. Altimeter & Altitude will help you measure altitude as well as elevation from the ground using location, barometer, and geographically mapped data. In addition, the existence of multiple maps allows the user to easily record the desired height and graph. The unique features of this application have made it a great choice for Android users.
4- Altimeter GPS application – Hike & Trek for iOS users
This program with a standard altimeter, barometer, and compass allows you to easily see changes in altitude. Also, the SOS emergency feature allows you to automatically send your location to someone close to you, if necessary. This feature makes most people who travel frequently consider this application as their first choice.
5- Altimeter Ler application for Android users
This program is designed in such a way that it gives you the feeling of being in a cockpit! This application provides complete information about location, weather and environmental conditions along with a variety of maps and good tracking features. Altimeter Ler can provide you with altitude based on both GPS and barometer. It will also estimate possible errors and notify you. It should be noted that this application does not show changes in altitude or altitude data graphically and simply, and therefore may be a little confusing for beginners, but the many features and options considered in the construction of this application. Has made it a good choice for Android users.
6- Altimeter application for Android users
This program does not provide as much information to the user as other applications, but due to its simple user interface, it will be very easy to read and track information, and therefore one of the best applications on the list today. Is. Of course, it should be noted that this program has a lot of ads, but if you provide a premium version, this problem will be completely solved.
Do we need to get a real altimeter?
If your mobile phone is equipped with a GNSS chipset and barometer, it will not be necessary to provide an altimeter, and tests have shown that smartphones are almost as accurate as real altimeters. If you have experience in using the applications introduced in this article or altimeters in general, please share it with us in the comments section.
