Great little app.

I got this app for the "map" elevation to calibrate my Garmins altimeter starting elevation. Gps in general is great for your coordinates; not so great for elevation. Unless youre in a skyscraper or a plane the gps value in this app is of limited usefulness. This is true of any non-pressure based gps measurement. It is unfair to criticize this app for that shortcoming of gps.
