Line-of-Sight

Hi,

I am quite new to OpenMAP. Seen a demo working and was
quite impressed. Even more when I checked the API documentation.

For a project (simulation model) we need to work with DTED
and DFED data. I have seen that there already is a layer
for DTED. This layer has the functionality to get the elevation
at a certain point, either via the closest point available or via
interpolation.

I am wondering how difficult it would be to implement
line of sight which (I think) depends on DTED and maybe
also DFED data. Or is this also standard functionality?

In addition we also need to calculate if a line/route
will intersect with the surface.

I would appreciate it if I could be enlightened in
these matters.

Thanks in advance for any replies,

Oscar Abbenhuis
