determine height of eye to .01 foot?"
The 'how' is probably by some software 'app'. There are some available where you can click on a location and the app will determine your altitude above sea level from topographic data. Obviously anything beyond the nearest foot is irrelevant for celestial navigation purposes, but extra digits do no harm. The 'why' here may be because "height of eye" is an input in my online lunar calculator. It's only required if altitudes are actually observed. Otherwise it's ignored.
And you wrote:

Good catch. Of course it's obvious that he meant local zone time.
