Getting altitude reading

[Danman1977]

I’m keen to get access to altitude information, I see the demo app using the barometer, how accurate is that?  I believe the ionic has an altimeter, is there access to this or can you get from gps data?   Keen to use this for topo maps in Rogains / orienteering.

You will find the reference below:

Geolocation Reference

Which states: readonly altitude

number or null

Height of the position, specified in meters above the WGS84 ellipsoid.

If the device cannot provide altitude information, the value is null.

readonly altitudeAccuracy

number or null

Accuracy of the altitude attribute, in meters.

If the device cannot provide altitude information, the value of this attribute is null.

import { geolocation } from "geolocation";

var watchID = geolocation.watchPosition(locationSuccess, locationError);

function locationSuccess(position) {
  console.log(position.coords.altitude);
}
function locationError(error) {
  console.log("Error: " + error.code,
              "Message: " + error.message);
}

The above should give you a good start.
