Measure Altitude: Altimeter 1.2.0

What is an Altimeter?

An altimeter, or altitude meter, is a device designed to measure the altitude of an object above sea level. The process of measuring altitude is referred to as altimetry, which plays a critical role in various fields such as aviation, hiking, and geological studies.

Why Use an Altimeter?

Many individuals, particularly mountaineers, have a need to ascertain their altitude relative to sea level. This can be achieved by measuring the surrounding air pressure with an instrument known as an altimeter. As elevation increases, air pressure correspondingly decreases, allowing for accurate altitude readings.

Overview of the "Measure Altitude" App

The "Measure Altitude" app offers a user-friendly interface for Android devices, utilizing barometric pressure sensors to deliver precise measurements of surface elevation. The application allows for offline altitude assessments and provides functionality for checking pressure altitudes. Using GPS coordinates, users can easily determine their elevation above sea level.

Limitations of Altimeters

In working with GPS altitude estimation apps, it is worth noting that many traditional altimeters encounter errors due to mechanical limitations at or near the barometric scale range (generally between 28.10 to 31.00 inches of mercury). Altimeters that lack mechanical stops near these limits may display errors that can reach 10,000 feet.

Features of the "Measure Altitude" App

• Calculates real altitude by measuring air pressure.
• Includes an elevation map feature for enhanced navigation.
• Facilitates simple altitude measurements.
• Measures absolute altitude using latitude and longitude data.
• Integrates pressure altimeter and Android barometer for accurate readings.
• Assesses altitude above sea level based on atmospheric pressure.
• Measures air pressure alongside altitude during flight.
• Provides altitude readings during activities such as skydiving.
