Very intesting application but does not appear to be accurate. I checked a
location where I know there is an elevation difference on the order
of 10-15 meters and the application only showed a difference of 2 meters,
and in the wrong direction, too.

As I am living near the beach, it seems that the height data is pretty
precise for me. However it might be a little difficult for the Google
Map engine to provide as correct data in places elsewhere.

Blame google if you really find there is such a big difference.

As far as I can tell (although I can't zoom in enough to be sure) the
app seems to be off by about 66% for my lot.

My lot drops about 6 feet from front to rear.

Doing a conversion from meters to feet, the app appears to show a drop
of less 2 feet. That's less than 33% of what it should be.

Seems close here. 1494' at the road and 1588' at the house. Yes I'm on
a small mountain with a steep driveway. Now I'm not sure if I'm doing
this right... Driveway is 528' long with a 94' incline, that's less than
an 18 degree pitch? I thought it was steeper?

hi, thanks for the reply.
I think it might come with the unit problem. I am currently in Aus, so
the data come back from google map by default for me is meter. I would
assume that the elevation data come back from Google Map engine might
be feet directly in US, so that you needn't do the conversion of
1m=3.28 feet. that might explain the 66% difference.
In the map display, I have updated to remove the "m" as the unit and
leave to the user to interprete it himself at his only convenience, as
I haven't spend much time to explore the different units in different
countries. i will spend some time to explore it and get a better
solution for that.
thank you for use it.
Some more features will come back soon. please your further feedback
are most welcomed.

thanks for the feedback. hope the possible unit problem does not
bother you

Mine (in the US) was most definitely in meters and I converted it to feet.
