Using osgearth_seed

Does the level option in --min-level and --max-level  represents the same levels we have in osgdem. Let say if i want to cache an area from google earth  till the highest resolution available (say 1m) then what should  be the values of these parameters.

They represent the subdivision level for quadtree tiles, starting with level 0.  Whether they match osgdem tree levels, probably, but I cannot say without testing.

However, there seems to be a new bug in osgearth_seed ... level 0 tiles aren't being cached for spherical mercator data sources. I will add this as a bug ticket.

In any case: the plan in the future is to have the user specifiy min/max-resolution instead of min/max level, since the latter isn't really meaningful.
