Wow!!! I almost feel like I'm looking at a completely new planet. It's easy to spend big amounts of time just scrolling through the map and exploring the various surface features.

Hi John,

Would it be convenient for you to upload a new copy of your map? It sounds like it's very detailed, and like Daniel's recent map, would probably make for fascinating viewing. I recently printed out and laminated a large copy of Daniel's map and hung it on the wall of my astro/geol lab classroom - looks nice! If it's not too much trouble for you to re-upload your map, I'd be curious to examine it.

(I was never quite able to figure out how to get your hi-res Venus textures to display in Celestia, but it sounds like the map to which you're referring shows essentially the same level of detail.)

I certainly understand if it's not convenient to do that for a single request like this, and I also apologize if it's poor etiquette on my part to ask for a big image like this, when I'm so new to unmannedspaceflight. Thanks for your hard work!

- Marek

you use what is called a VT ( virtual texture )
my celestia VT is here
http://celestiamotherlode.net/catalog/show...p?addon_id=1070
for 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
-- picassa
https://plus.google.com/u/0/photos/10269590...901291398562941
right 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=VIPS

the .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
