Altimeter X vs Elevation

iOS/GPS altitude Altitude estimated by the device's location service. It works reasonably well in most situations but can't track small changes and can be unreliable indoor. Barometric altitude (iPhone 6 minimum) Altitude based on the device's barometer. This is how most hardware altimeters work. It can track very small relative variations but must be calibrated with weather data or GPS. Calibration with weather data grabs current sea-level pressure and temperature at your location from a nearby weather station. GPS calibration takes the current iOS/GPS altitude as a starting point then uses the barometer to track changes. Elevation database This method displays earth surface elevation at your location by polling an elevation database. It works even with very imprecise location data but requires network access. Surface elevation usually includes buildings and trees.

Find your current elevation, altitude, and height above sea level easily with this altimeter/barometer app. ## Elevation Finder ## This app helps you observe the elevations of all locations on the surface of the earth by simply touch and move the map around, or input the address/location name. You can also find the elevation of your current location by using online database, built-in GPS, or barometer on your device. Elevation data benefits flood prevention, prediction of water levels in rivers, lakes, and seas, etc. Thus, knowing the elevation of places is very crucial if you are looking for a flood-free house, or planning for a hiking trip, and more. ## Cloud-based Altitude Data ## The easiest way to find altitude of any location on earth. By simply point on the screen, you can get the elevation data from a coordinate location point. “Range Mode” is available for altitude comparison (by graph and line) of each point between two selected locations. ## GPS Altitude Data ## Use built-in GPS on your device to determine the altitude of your current location. The altitude data of the area you walked-through will be recorded and displayed as a multicolored line on the map. The colors presented on the line indicate different heights. Precision indicators (horizontal resolution and vertical resolution) are displayed on the screen. ## Barometric Altitude Data ## Use built-in barometer on your device to determine the elevation of your current location. You can either measure the elevation from raw barometric data, or relative pressure from sea-level. Like GPS data, the result is displayed as a multicolored line. To get the most accurate data, it is recommended to adjust the sea level pressure and temperature prior to the measurement, and set the offset or calibration value if necessary. ## Standalone Barometer ## You can use this app as a standalone barometer. ## Air Pressure / Altitude Calculator ## Atmospheric pressure and/or altitude at your current location are calculated from known altitude, pressure of the location, temperature and/or sea level pressure. ## Support of Coordinate Formats ## This app not only displays regular latitude and longitude data, but also supports many coordinate systems such as, Universal Transverse Mercator (UTM) coordinate system and Military Grid Reference System (MGRS) and more. ## Export of Data ## From this app, you can export many useful information including timestamp, altitude, pressure, and coordinates.
