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.

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.

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 )

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, 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.

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:

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.
