    You can add your recorded altitude to the altitude above sea level known or measured at your home point.

    You won't get the P3 to provide it.

    It's the same for the P3 as the P4.
    It was a firmware update that introduced the GPS altitude in Exif data (barometric altitude is still there too but in a different field.
    BUT .. the GPS altitude data is garbage because GPS altitude accuracy is woeful and changes frequently.
    GPS altitude data cannot be trusted as it is commonly +/- 200 feet out.
    Take a few photos from the same spot over a 5 minute interval and check the variation for yourself.
