Hi Terry,
I have quite the same goal to reach, so I would happy to cooperate and create a
usefull toolchain.
At the moment I use VPB to generate the database.
I'have tried osgEarth but the VPB Plugin over there doesn't work very well, it
loades all tiles at highest LOD and my FPS falls down to less than 5 fps.
So osgEarth is not an option.
At the beginning, I had a lot of problems to compile my datase ( ~800GB raw
data.
with 64 Bit and the newest VPB it now works quite stable, resuming works and it
is possible. With compressing all geotiffs with LZW the build time is reduzed
dramatically from several weeks to days ( 16 Cores, 12 gig ram, several HDDs
for source data)
About this task, I have written a detailed documentation which I plan to
publish on VPB wiki.
The following tasks are not solved but are only my current todo list:
adding forest to database based on openstreetmap shapes. Use of LOD to
blend forest on configurable distance in and out
flattening/pulling ground to specifig height of the geocentric
database in configurable areas to provide complete flat areas (or other height
feature) for flat airports or other submodels.
adding streets and other feature of OpenStreetMap and other sources
Would you like to modify database offline or online during runtime via
pseudoloader?
Both approaches are quite interesting I think.
I would be happy if we could create a Toolchain and write a detailed
documentation (I'd like to do this, because I struggled myself often at the
beginning due to lack of documentation)
Cheers,
Torben[/list]
