Using the figure file satglobe, which I will upload into the MATLAB Central File Exchange shortly, you can generate fully rendered, rotatable, zoomable views of earth as seen from space. This screen capture was rendered with OpenGL, using a camera light at infinity and specified diffuse and ambient material reflectivities.
The image data was obtained from NASA; the map projection, political boundaries, and gridlines were created using the Mapping Toolbox.
Rendering can be as much art as science, and so graphic design aftertouching on the brightness, contrast, and specular point anomalies was done using standard image editing software, after the image was created in MATLAB. I do not have the image processing toolbox, but I presume this could easily be accomplished with that instead.
Using the SATGLOBE function, the command syntax for this image was:
material([.03 1.5 0])
The OpenGL renderer seems preferable for screen displays, whereas the Zbuffer renderer seems better for image captures such as printing to a JPEG file.
For details on how to create the underlying image, and for higher resolution satellite imagery, please contact the author.

This is currently only the JPEG image.
first time i just visited i think it will be more interesting and improve th iq.
hey "use less" (that describes you fully). read the friggin text, there is code telling you what to type
Nice picture, especially the shading. I'm looking forward to seeing the M-code.
Major companies are now routinely using NASA satellite globe imagery in their presentation materials. With my software, I am handing you the ability to generate such images yourself - rendered, manipulatable, and plottable - without having to go through the 100 or so hours of development work it took to figure out how it's done and then tweak the results to make them visually appealing.
Hopefully some folks will find useful applications. Cheers.
What the hell we want one more .jpg image
