Re: [Paparazzi-devel] Flight Plan - AGL vs alt="ground_alt+x"

[Jeremy Reinertsen]

Thanks Gautier,

Just to close the loop (and now that I have the answer)  I can look at the 
"flight_plan.dtd" file and see that waypoints are described as follows:

<!ATTLIST waypoint
name CDATA #REQUIRED
x CDATA #IMPLIED
y CDATA #IMPLIED
lat CDATA #IMPLIED
lon CDATA #IMPLIED
alt CDATA #IMPLIED
height CDATA #IMPLIED>

So there is a height attribute that can be assigned to a waypoint? It's not 
explicitly described in the wiki but it is implied (so to speak) in the .dtd 
file and if I had played around with the settings then I would have 
eventually discovered it for myself. But I'm not quite experienced enough to 
be able to derive these things by myself as yet.

I really do appreciate your help ;-)

Cheers

Jeremy

Hello,

When you set a waypoint in the flight plan, you can use "height"
attribute instead of "alt". It will set the altitude to
ground_alt+height. You can also do the same in any block where "alt"
attribute is available.
