I am very much interested to know how to create the custom maps as we see on the following links.

and

I would like to know what is the best and robust possibility to create such a kind of customized maps that we can use for other purposes as well. I am sure this is not developed in Flash.

Any suggestions, references, articles etc is highly appreciated.

Kind Regards,

Faisal
