(I was never quite able to figure out how to get your hi-res Venus textures to display in Celestia,
you use what is called a VT ( virtual texture )
my celestia VT is here
http://celestiamotherlode.net/catalog/show...p?addon_id=1070for the FULL res you need to download EVERYTHING ( levels 0 through 7 )
this is not the best forum for that discussion ,have a look over at Celestialmatters .
http://forum.celestialmatters.org/( replacing the dead shatters.net forum)
as to the full res image
131072 x 65536 pixels
it is a slightly resized version of the C1data ( 168,876 x 84,438 pixels )
http://pds-imaging.jpl.nasa.gov/data/mgn-v...5-midr-c1-v1.0/a crop around a rather well known area -in orthographic projection
( full res)
if the "imagbox" clickable image dose not work

https://plus.google.com/u/0/photos/10269590...901291398562941right now ( i am look at my storage archive ) i have a xz compressed copy in vips image format AND a isis3 cub file
the software i use for very large images is vips and it's GUI nip2
http://www.vips.ecs.soton.ac.uk/index.php?title=VIPSthe .v format is a RAW with a 64 bit header that describes the image size and format
( and can be imported into ISIS3 using "raw2isis")
the compressed archive is 4.5 Gig
the uncompressed image is 8.0 Gig
i can post it to my Google drive
BUT
in its current format you will need to be able to Uncompres the XZ compression
and isis or imagemagick can "fudge" the vips format as a raw +64 bit image
or
use vips ( nip2 installs on Linux, mac and windows )
or
I can resize it and use a different format like to a ppm or pgm or a isis3 cub
or any gis format that GDAL supports
