Does anyone know of a not-topographic version of something like this?

http://astrogeology.usgs.gov/Gallery/MapsA...oon.html#Globes

I need something I can cut-out and assemble using a 10cm sphere as a former.

Any pointers much appreciated!

Cheers

Doug

The one chuckclark posted a couple of days ago no good?

http://www.unmannedspaceflight.com/index.p...st&p=130501

Good call!

Of course, the other way to get a greyscale USGS one...

Is to print the Topo one in black and white

Oh - and then invert the image ( the Mare look better that way )

Not perfect - but it will do the job - making a scale model with this...

Doug you find the map, I will make the petal projection.

Awesome - there's a 4k res map on this http://www.celestiamotherlode.net/creators..._2k_4k_Moon.zip

Steve's 8k Map would also do the job - http://laps.noaa.gov/albers/sos/moon/moon_...olor_brim16.jpg

Doug here is your petal map, this is the first time I made such a map, hope I did not make a mistake. My cut passes from 0 deg longitude, not 15 deg as in the USGS map.

Doug, where did you get that realistic terrestrial globe with clouds and all? I've been after one of those for years.

Here is another one with Steve's 8K map.

The imaginative 'just globes' ( http://www.justglobes.co.uk/ )

It's actually about as good as I was expecting, and if it gets enough light, populated areas then glow in the dark

I'll do photos when I've made my scale Moon to go with it

Huge thanks to Tayfun - those are AWESOME!!!

Doug

Brillliant, thanks for the link. Pity they don't do a matching moon to scale. If I have dealings with them maybe I'll suggest it.

Hence why I'm printing the two halves of Tayfun's great projections as 16cm squares, to make a 32cm circumference (thus just over 10cm diameter) sphere :0

Doug

How do you create such projections? I have a Photoshop plugin which creates an eqautorial-centered (?) projection, named Flexify, but it's quite hard to get all pieces matching at the poles!

I just had an idea about how to build a 500$ globe just for 50$ and I was going to print an equatorial world map, but a polar version would be much better!

I'd lie to use one of these:



They're very cheap, very large (up to 50cm diameter) and quite spherical inside:


Of course I'd place it up-down, covering the neck with the structure which holds the "globe".

Jumpjack this is a composite map consisting of 13 parts for each hemisphere and it is not possible to create it with Photoshop. I am using a custom program that I wrote. I have made the 0-75 deg lats to overlap for 1 degrees. 0-75 degrees are in transverse mercator projection, each petal is 30 degrees wide and centered in each petals central longitude. Standard latitude is 0 degrees (hence the straight edge). Polar region from 75 to 90 degrees latitude is in Lambert Azimuthal Equal Area projection.

I think the best way to create a cheap globe would be to match one of these petals to a cheap earth globe in scale and paste it with a good decoupage medium (I don't think others will work). Then spray it with a water based finish. I am planning to create an Io globe in this way.

Maybe you're able to write photoshop plugins, just... you didn't yet know!

Why wasting money on an earth globe? Just buy a "garden lamp cover"
http://www.fratellidelpiano.com/index.php/cPath/177_182
(sorry, don't know any english site)

It will cost 1/2 or 1/3 than a same-size earth globe. ;-)

I forgot saying that IrfanView is a freeware program which supports Photoshop plugins.

edit:

Just found list of freeware compatible with Photoshop plugins:

Thanks for the link jumpjack, I will check it out.

A nice 30 cm globe for students here costs about $25 (in fact the one I have is italian, made by Nova Rico Florence), it is a perfect sphere, has a good surface to glue paper and already has latitudes and longitudes for using as a guide during the gluing process.

Doug and others looking for a moon globe to match the 16" inflatable Earthball may be interested in this. Using the handy 3/11 rule I calculated the required diameter to be 4.36" I came across this Replogle one amazingly quickly.

EDIT Even better price:

In these months I was not able to find a suitable program to generate needed projections.
I think PROJ could be actually suitable... but it's very complex, and I can't figure out the right command line to obtain the required Transverse Mercator and Lambert Azimutal projections.

Any clue?

A minor request. Would it be possible to get a 6 inch diameter petal or gore development for the moon (albedo and topographic). I am looking to make a couple of globes to have with me at the telescope and for outreach activities.

Thanks.

Randy Shelaga

Look at post number 9 - and scale appropriately

The 'width' of each petal half needs to be Pi* r ( i.e. total circum = Pi * d )

Doug

The math is simple and the results good, the real intent is to get both an albedo features and topographic globe, with the albedo having major features identified and meridians.

Any suggestions?

Randy Shelaga

Randy, find maps that you want (in simple cylindrical format) I can project them for you.

Tayfun,
Thank-you, I will dig up the appropriate maps and let you know.

Randy Shelaga

Tayfun, it's cool you can make projections for us... but it would be even better if you could publish your program! Is it possible for you?

Else, maybe you could help us writing a GIMP plugin: I just discovered GIMP can be used to create transverse mercator projections uisng a scripting language:
http://forum.cartographersguild.com/showpo...amp;postcount=4

A thing I can't understand is which size the azimutal projection image must have, once I know the size of the UTN projection.

For example, I created an UTM 62x31 cm wide; with Wilbur SW I can create the Lambert Azimutal Equal Area, but program asks the size of the output image... and I do not know what to answer!

To create the projection using Wilbur:
File-->Open (color image texture)
Surface-->MapInfo (specify -180,180, 90,-90)
Window-->MapProjection-->Lambert
... then what?!?

In your experience, which one is better to glue over a solid sphere? flower petal, or just transverse mercator? I'm in trouble with both of them...

EDIT:
Maybe I could try writing a script for Scribus, as I already know Python. What I don't know are the projections formulas...

EDIT2:
Just found also GIMP does support python:
http://www.gimp.org/docs/python/index.html

does your program support humongous images?

by the way, could you please project this simple grid? I want to do some tests before starting with real map.

thanks.

Jumpjack, I am too busy at the moment that being unable to do anything astronomy related and just watching gives me pain.

The last link you posted does not seem to work.

right, I fixed the link.
but I didn't understand your first sentence.

jumpjack I meant I wish I had more time to help. I will project your grid as soon as possible.

OK, I found InfranView which will accept PhotoShop plugs-in. Where might I find a plug-in to create icosahedra or gores?

My page on world globes (in italian):
http://jumpjack.wordpress.com/2009/02/06/c...le-in-plastica/

jumpjack here are your grids. When I projected your grid it looked rather strange, then I realized it spanned 350 degrees! I had to fix that, also grid cells are not uniform probably due to antialising.

Really?!?
Ops... I generated it automatically with a python script... didn't notice the missing degrees.


Thanks for fixing and projecting.
I don't need a very precise grid, it's just to have a preliminary look to how my globe will result and to see if I can size the "flower" properly.

Is anybody able to tell me if this Java Map Editor is suitable to create such flower petals projections?
I'm getting weird results!
