Glider computers - what's important?

I'm using an elevation database accurate to less than one meter on a 100m
grid. That's far more that accurate enough to provide a glide footprint. I
choose not to display this as a visible map since it make more important
data hard to read and takes processing power. I just display airports,
turnpoints and the glide footprint.

Hi,

I want my glide footprint on the moving map.

This depends very much on accurate terrain elevation data. I am not sure
how good the publicly available data is. It does paint pretty pictures
in any case.

Elevations for airfields are very accurate and those for charted landouts
at least at GPS-accuracy.

Ciao, MM
