View Full Version : Looking for a Venus base
10-07-2011, 02:36 PM
I want to do a Venus map for my game but I can't find a proper base for it. I need a map of Venus with altimetry/topography with a good accuracy. I've just found some maps with false colours (flashy blue, yellow and red) and it's not very accurate...
There are a lot for Mars, but not for Venus.
Oh! I used to work on classic surface maps. But another format will do.
Tell me if you have one or know a good place to find it.
Thanks by advance.

Do you realize how NOT inhabitable the surface of Venus is?
Imagine building a city on an active volcano at the bottom of the ocean ... only the water is sulfuric acid.
Try looking here:

Would the map on this page (http://en.wikipedia.org/wiki/Venus_series) do you?

Has anyone seen toff recently? He had what looked like a radar surface map of Venus for his Venus Transit Map, but I don't recall if he said where it came from.
If that false color image is of sufficient resolution, you might be able to remap the colors to a more usable grayscale heightmap. As I recall, there's a topo made from Magellan data that uses a rather garish hypsometric scheme. If that's the one you have, then the reds are high altitude, the blues are low altitude, and the grays are areas where no data was captured. I considered using that image to get a displacement map for a 3d model of the planet, but I never had cause to look beneath the clouds, so it's sitting in one of my archives somewhere. I seem to remember that it was quite low-res, though, so I'd have had to do some pretty serious processing on it to get a usable texture, anyway.

Quick googling gives us: http://planetpixelemporium.com/venus.html - but I don't have time this morning to sift through the results to find a better one. (Besides, you can easiyl do that part yourself.)
And yeah, if your game is hard sci-fi you will need to do some serious thinking on that base. Even if it's a soft sci-fi setting, consider a city on the talles mountains, and even then a well protected one - thick walls, dome shapes to provide pressure resistance, etc.

Thanks a lot everyone! I had not looked on the guild news for quite a month.
Actually, I've already found quite good venus maps and I have worked on my elzevir venus map since then (but it's not finished).
I'm a scientist, so I know quite well about the harsh conditions on Venus atpollard. But my Elzevir's world is a kind of uchronia, so I stated that Venus and Mars were suited for life (but with certain conditions nevertheless). Venus and Mars are in the habitable zone and both had know an era (sometimes very short) with surface water bodies and a thicker (for Mars) or less carbonated atmosphere (for Venus).
I hope I am gonna be able to finish the map before 2012!
Again, thanks for your kind answers.

Are the maps /base images you found freely accessible? If so, could you post a link please?

I think so, it's provided by the NASA on the IAU/USGS website. For Venus, here's the link :
There's plenty of interesting things on this site by the way!

Wow, that one was a hard one... Finally, my elzevir Venus Political Map then.
In my Elzevir World, Venus has a moon called Neith... But just now, I'm gonna wait a bit before doing it.

This one was a harder one!
This is my Elzevir Political Map of Venus then. Venus has a moon in my Elzevir's world, which is called Neith and is inhabited. I'll do it a bit later...
Hope u enjoy it.

if you still need a topographic map i recently ( in February ) completed a massive 12 gig ( 131072 x 65536 Px. ) RGB image of the SAR radar
and a 4 gig 16 bit topo Height map( 65536x 32768 Px.) reworking the SAR data to get the height data from it
if people want i can resize it down
some links to images OF it
the C-1 compressed Magellan SAR DATA ( destripped )
the Topo Height data
rendered Venus Height data

Superb! Thank you so much for sharing that with us!

Very cool - how is this licensed?
07-25-2012, 10:36 PM
how is this licensed?
the standard NASA license
but i tag on CC-BY-SA
right now i only have texture add on for Celestia published
but a 16384x8192 or 8192x4096 Px. image can easily be put on a torrent

Well, thanks a lot,
I'm thinking to improve my venus map as I did for mars, so... It's a good start for doing it I guess!

here is a link to a 16384x8192 8bit gray image of the SAR
-- this map --- 50.4 Mb ,16kVenus.zip
0 deg long is in the center
90 north to 90 south
-180 west to 180 east

Well, I changed my mind a little bit...
My Elzevir world is an uchronia with a different technology progression than our history line, but it's current date is 1948, and I think the NASA picture is far too detailed than possible in this context. So, I found another base from USGS based on altitude lines.
Here are the results for the "normal" and the political maps.
Thanks again for the support !

Hey that's really cool! Nicely done.
12-17-2012, 03:43 PM
Thanks a lot Arsheesh !
It was a long term work.
