How to find elevation on Google Maps in a web browser
- Type your location into the search bar on the left side.
- Click the “Menu” bar, which is next to the search bar and is represented by the three horizontal lines in the top-left.
- Hit “Terrain” to show topography and elevation.

Is Android GPS accurate?
For example, GPS-enabled smartphones are typically accurate to within a 4.9 m (16 ft.) radius under open sky (view source at ION.org). However, their accuracy worsens near buildings, bridges, and trees. High-end users boost GPS accuracy with dual-frequency receivers and/or augmentation systems.
What is Android altitude?
The altitude is the altitude above the WGS84 reference ellipsoid. It is not the altitude above ground level or sea level.
How accurate is phone altitude?
The most important altitude measurement tool in your phone’s arsenal is the GNSS/GPS receiver. If your phone can find at least four satellites, with one directly overhead, you can usually get an altitude reading accurate to within 10 to 20 meters (35 to 70 feet).
What keeps turning my location on?
Mostly, system apps turn on GPS for accurate results. If your iPhone’s location is turned on then it means that your device is sending location to apps or Apple. Moreover, the location turns on whenever you connect your device with Wi-Fi even if the “Remotely locate this device” option is disabled.
Why is my location wrong on my Samsung phone?
For Samsung smartphones running Android 10 OS, the location information may appear inaccurate if the GPS signal is obstructed, location settings is disabled, or if you are not using the best location method.
How accurate is GPS on a Samsung phone?
There continues to be improvement, and you’ll see indoor accuracy of better than 10 meters, but round-trip time (RTT) is the technology that will take us to the one-meter level. If you’re outside and can see the open sky, the GPS accuracy from your phone is about five meters, and that’s been constant for a while.
Can my phone tell the altitude?
Altimeter Ler (Android) Altimeter Ler (available on Android) gives you a full readout of your location and environmental conditions plus a variety of maps and good tracking features. It can calculate altitude based on both GPS and barometer readings and even tells you the estimated error of the GPS data you’re getting.
How to get accurate altitude from GPS-Android?
The $GPGGA sentence already contains the corrected altitude data above sea level. So, simply create a listener to NMEA-strings for your LocationManager and parse the messages: You can either replace the altitude of the last Location object received through a location listener, or parse the whole new location through NMEA.
How does the position of the satellites affect the accuracy of the GPS?
Where the satellites are at the time when the readings are taken will also effect the accuracy of the altitude that the GPS system can calculate. This is due to the errors inherent in the system. The GPS device uses the distance to the visible satellites and their geometric positions to fix a location.
How can I improve the accuracy of my GPS?
To improve the accuracy of your positions, consider using a GPS receiver that supports differential corrections. If you are using an iOS device, you must also choose one of the GPS receivers supported on iOS.
How to get accurate altitude from a barometer?
So, simply create a listener to NMEA-strings for your LocationManager and parse the messages: You can either replace the altitude of the last Location object received through a location listener, or parse the whole new location through NMEA. Another approach is to measure the altitude from the barometer.
