Inkscaping a Globe with latitude, longitudes.

I wanted to have a globe with those latitudes & longitudes on it.I was doing it manually earlier by duplicating and resizing, but there's the clone tool to do that easily. Here is a tutorial on how to do a simple globe with latitude/longitude. I have a very bad color sense so you can surely do a better job with colors. :)
Here is what we can have



1) draw a perfect circle (holding ctrl key) with no fill and black stroke.
2) Now we need to do some cloning.
Select the circle and go to edit-->clone-->create tiled clones.
Select 'simple translation' for symmetry and following settings for shift and scale.

3) We will get something like this.
Now select them all and go to edit-->clone-->unlink clone (or shift+alt+D)


4) Now draw a straight line from top center to bottom center to get the equator / meridian.
5) Now duplicate this and do object-->rotate 90 degree.
We have the latitude & longitudes. Now select these and go to path-->combine.

6) Now lets get back to the original circle give it a radial gradient.
And place the latitude/longitude globe over it. ( Use align and distribute tool to center the circles)
7) You can also give a radial gradient to the latitude/longitudes, to get something like this.
8) Now you can write something at the center of the globe with bezier tool using the latitude/longitude as a grid.
9) Now select these letters and move sideways for editing. Give them a color fill and remove the stroke.

10) Do a path--> union of these letters and apply path-->simplify.
11) Give the text some suitable color, do some resizing(decrease height holding shift) and place it over the globe.

Further you can do things like giving the text or the globe a shadow effect etc like the one by heathenx here.



[ Edit: Stumbled upon this youtube video. Its really cool how you can build up on the globe layout... though its pretty tough to draw ]
The whole how-to in PNG format is available at deviantArt here. Happy Inkscaping.

Hi man thanks for the comment! Anyway now I putted a babelfish translator for you in english, now it's easier to you read my blog, nice blog u got, congratulation and nice pic of your mobile! And other thing, to tell the truth i'm new at inkscape and gimp and this design stuff so we can change experience keep in touch! See ya! I'll add you blog at my blog! peace!

These imaginary lines are actually called Meridians and Parallels.

Meridians are expressed in degrees of longitude, or how far a place is away from the prime meridian. The prime meridian runs through Greenwich, England.

Imaginary lines that run east and west on a map. Parallels represent degrees of latitude, or how far a place is away from the equator. The equator's latitude is 0° and the poles are 90° south and north. One degree of latitude equals about 69 miles.

Longitude together with latitude forms a grid on which it is possible to locate almost any place on the earth.

There is a mistake in the tutorial.
Parallels work different from meridians; They never cross each other, they are parallel to each other.
