I just had a quick look at Munich (EDDM). Activating all layers it looks
like that the most important stuff is included. (My hometown Holzkirchen
is missing, but I could clearly identify where it should be located as
the railway interscetions are there...)
What I've seen is that there are only two road types. I think this could
be limiting in the future. (As line data can dramatically increase the
triangle count it might be necessary to switch off the smallest visible
roads.)
So, what about having those TerraGear-Layer types:
roads_freeway (a big, multilane highway, like a German Autobahn)
roads_class1road (a state road, like a German Bundesstrasse)
roads_class2road (a provincial road, like a German Landstrasse)
roads_class3road (a local road or a simple street in a town)
roads_track (not used for regular traffic, mostly access roads
for farming)
roads_walkingtrack (ok, that's getting excessive...)
If we are increasing the type count, perhaps one step further might make
sense:
roads_freeway4lane
roads_freeway6lane
roads_freeway8lane
(for Germany that should be engouh...)
This allows a more detailed vectorisation of the data. A current benefit
could be, that the different road types generate different line widths.
And even if the texures are the same in the beginning, it allows a
selection of the relevant types for scenery generation (e.g. if we'd
have roads_track data it still might be too much for current CPU/GPUs).
CU,
Christian
