Celestia Forums

Folks, The Celestia world weather satellite textures are moving to a new folder on march 1, 2005: The new URL will be: www.meteo-maarssen.8m.com/data/textures cheers, Ton Lindemann Netherlands BTW: Is there any interest in having a daily (00 UTC) sea level pressure map for use in Celestia?

To all,

The daily upload of satellite based earth images was temporary aborted because of system maintenances. Services resumes today (January 5th).

Cheers,

Ton Lindemann

To all, I'm sorry, but life weather in 3D is impossible, it is a dream that would be forever. It is not available. Not in any forecast model and not from satellite. Satellite data is always 2D; you can't make 3D from it. Why: IR is only mapping surface temperatures it can see, not mapping the temper...

Seb,

Maybe a bit confusing, but both are IR images. I made one version in false colors to show cold cloudtops and one version as 'speudo-visual'. But actually they are both IR based and superimposed on a world map.

Hello,

For better understanding, "geo" is refering to earth. Astrogeologic and astrostratigraphic refers to "geologic" maps of other celestial bodies. Thus: have anyone a source with cylindrical geologic maps of planets and moons?

Thanks,

Ton Lindemann

Hello,

Does anyone have sources for cylindrical astrogeologic/astrostratigraphic maps of earth, planets and moons?

Thanks,

Ton Lindemann

Hello,

I've uploaded new textures to the motherlode:

vesta (basalt, topo, lok),
titan topo,
gaspra geologic,
phoebe lok (from Voyager).

I don't know when they available for download;

Hello; I was trying to create a geological texture for Ida, but it seems that the orientation of Ida in Celestia is upside down. P. Stooke's Ida north seems equal to Celestia's Ida south! Is this right, or did I missed something? Can anybody explain? Anyway it seems that you should rotate your Ida-t...

You should also take a look at:

http://www.satsignal.net

This site is offering as set of satellite imaging tools to plot, animate and rotate geostationary weather satellite images and polar orbiters as well!

Hello,

If, then please don't forget Meteosat! Anyway a daily service (only for 12 UTC and IR and worldcover) is available from my site. Look at textures for daily IR service.

Cheers,

Ton Lindemann

Selden,

Thanks, I installed image magick and need to study the commandline options first.

Folks, The earth speudo-visual (simmulated visual) is available now, but only once a day as with the earth-ir and only for 12 UTC. Filename convention identical as the infrared version; earth-cl[yymmdd].jpg, thus earth-cl041112.jpg URL: www.meteo-maarssen.8m.com/data/celestia/earth-cl041112.jpg Both...

Hello, I found and prepared some Vesta textures from the HST. Available are: -vesta-lok -vesta-lok-mask -vesta-topo Here I need some help. As a new user I'm not familair with Celestia. I can't display them with vesta_altmaps.ssc example; AltSurface "Topography" "sol/vesta" { Texture "vesta-topo.*" }...

Seb, This is a good conclusion. In general airmasses, or maybe better weathersystems as high's and low's are moving east on earth at mid latitudes. But moving west near the equator (look at e.g. hurricans: traffeling from Africa to the Carribean and there via North America to the northern Atlantic/E...

Selden, Thanks for your answer. My screen is set on 1024*768 and soon as I go to a telescopic view with a smaller field as 18° then the sun's disc is larger in any mode. I didn't use the scaled disk option, but tried the two others. In both other options moondisc's are smaller at greater maginificat...

Hello, I'm not sure if it was a bug, but I reported as it was. I found that the moon was much to smal, or the sun to large, during a view of the solar eclips of 11 august 1999 in Europa. The moon can't cover the sun, while I was searching if Celestia shows some corona effects during the eclips. Anyw...

Hello, I was checking out the European 11 aug 1999 solar eclips and found that the moon is very much to smal to cover sun (or is the sun to large?). What you get is a 'ring of fire'. Set Celestia 1.3.2 to 11 aug 1999 at 49N-6E around 10:30 UTC and watch the eclips from earth surface. It should be to...

Hi, What you actualy see is a temperature map of the earth for a given time. On the raw images/data cold is represented as white and heat is black. Thus the cold cloudtops appears as white and the heat of the deserts as black. The satellite is measuring the radiation from the surfaces he can see. It...

Thanks Selden,

I will switch the discussion to the your FAQ-list.
