[Openev-discuss] MAX_LOd

[Frank W. <war...@ho...>]

Folks, 

I have upped max_lod in the gvraster.c module to 7 meaning that the highest
lod (6) has the 256x256 tiles reduced to 4x4.  This is a reduction factor
of 64 in each direction.  Due to the need for texture overlap there is little
point in taking the reduction any further.   For optimal performance imported
datasets should include overviews 2, 4, 8, 16, 32 and 64. 

This won't likely make much difference in performance, but should improve
the averaged appearance of large radar images in overview mode. 

Best regards,
