This is probably a dumb question but is there any rule of thumb or logic
to use when creating terrain databases of differing resolutions that
will reduce edge differences.

 

For example if I create a full world database from the Blue Marble
images and higher resolution local area database from NAIP 1 or 2 meter
images how should we decide the number of tile layers to limit the
transition effects?

 

Second question - has anyone used VirtualPlanetBuilder with 6in/pixel
rasters?  Will it work with a 1.8G SID file without choking?  I would
like to create a terrain dataset to support driving separate from the
flying dataset.
