[osg-users] [vpb] How to reduce the size of the terrain

[Qiaokun Lefei]

Hi,

I used the following commands to create a terrain database
osgdem -d dem.tif/ 
-Layout 0 ../day/ --tile-image-size 1024 -o root.ive -O "compressed"

I know that the default way of compression is "--compressed" by reading source code. What I wanted to know is that if there is any other way to reduce the size of the terrain datebase.

Thank you!

Cheers,
Qiaokun
