What program produced this pic?

Some eight years ago in the Nov-Dec 2001 issue of Newton magazine (now defunct), an article, A Rare Glimpse of Mercury, was written by John Laven and Richard Weiss, both from a company called Stellar Insight. The article included the picture displayed in the attachment.

I wish to find out the name of any computer program which can generate such overview type images.

Hoping someone can help. Thanks.
