Now we write the corrections applied to altitudes into the header comment section of GPX files. For example, here below the header comment of a GPX file exported with EGM96 correction enabled and 10.5m of manual offset:
...
<!-- Track Statistics (based on Total Time | Time in Movement): -->
<!-- Distance = 135 m -->
<!-- Duration = 01:42 | 01:35 -->
<!-- Altitude Gap = 1 m -->
<!-- Max Speed = 6 km/h -->
<!-- Avg Speed = 4.8 | 5.1 km/h -->
<!-- Direction = SW -->
<!-- Activity = walking -->
<!-- Altitudes = Corrected using EGM96 grid (bilinear interpolation), -10.500m of manual offset -->
...
Currently there is no way to know which altitude has been written into a GPX files (Orthometric or Ellipsoidal). It would be fine to add the information into the header comments.
