1. show/hide toolbar

Press “X,Y” button to show/hide coordinates
(You may change how coordinates format by going to setting menu)

Press blue "Barometer” button to show/hide barometer toolbar

 
 

There are three main data source for altitude data.

Cloud (1.1 Point/ 1.2 Range)
2. GPS
3. Barometer

  1. Cloud

  1. Select “Cloud”

  2. Select “Point” mode

  3. Move map to desired location

  4. Press “+” to fetch data

  5. Result will appear on the screen

  6. Change unit between meter / feet

1.2 Cloud (Range)

Get elevation data of one point from cloud.

  1. Select “Cloud”

  2. Select “Range” mode

  3. Move map to first location

  4. Press “+” to fetch data of first point

  5. Move map again to second location

  6. Press “+” to fetch data of second point

  7. Graph will appear on the screen

  8. Change unit between meter / feet if needed

(Meaning of coloured line)
Red - Lower Altitude
Yellow - In between
Green - Higher Altitude

1.2 Resize graph view

If you find graph too big. You may resize it by holding result bar and drag down to reduce graph size

  1. Hold result bar and then drag down. Release finger

  2. Graph will be resized

 
 

2. GPS

2.1 GPS Mode

Get elevation data from your device’s build-in GPS

  1. Select “GPS” Mode

  2. Press record button to start

Screenshot 2019-08-17 01.22.32.png

2.1 GPS Mode (Started)

  1. Recorded elevation will plot on the screen.

  2. Adjust altitude offset if needed

  3. Press “Pause” button when done capturing this section.

2.2 GPS Mode (Paused/Completed)

  1. Graph of all sections will be plot here

  2. Continue measurement if needed

  3. Export all recorded point to text file. Then you may share to other apps if needed

  4. Delete all recorded points

3. Barometer

2.1 Baro Mode

Get elevation data from your device’s build-in barometer

  1. Select “Baro” Mode

  2. Select measurement mode

    • Relative mode - Measure relative altitude

    • Raw mode - Measure altitude from true pressure value

  3. Check calibration options

    • init h - Set initial altitude (required for relative mode)(not used for raw mode)

    • Pa+- - Adjust final pressure value

    • h+- - Set altitude offset

  4. Start recording

The rest is the same as GPS mode. Please refer to that section.

FAQs

1. What is this app source/reference of elevation you use in this App?

Short answer: ALOS Global Digital Surface Model JAXA & Google Maps Elevation API

ALOS

This data set is a global digital surface model (DSM) with horizontal resolution of approximately 30 meters (1 arcsecond) by the Panchromatic Remote-sensing Instrument for Stereo Mapping (PRISM) on board the Advanced Land Observing Satellite "ALOS".

Google Map Elevation API

The Google Maps Elevation API provides elevation data for all locations on the surface of the earth, including depth locations on the ocean floor (which return negative values). In those cases where Google does not possess exact elevation measurements at the precise location you request, the service will interpolate and return an averaged value using the four nearest locations. Elevation values are expressed relative to local mean sea level (LMSL).

2. My elevation is not accurate?! 

In those cases where ALOS/Google does not possess exact elevation measurements at the precise location you request, the service will interpolate and return an averaged value using the four nearest locations.

Please use GPS mode to measure altitude with satellite. This will also helps when you want to measure height above tall structure.

For GPS mode and Barometer mode, altitude results may fluctuate from quality of the signal.
