Hi Kasim, Gosh lots of questions there to pick up. What I did yesterday is mail a few people here to ask if I could use their maps to make a demo. I have had several responses with an ok. So I went ahead and did it. I hope that its ok with the others and if not I will remove the link.
I have made a movie showing what its basically all about. So I have taken RobA's progressive detail world maps which show how you might get the basic forms in at world scale. Then lower down there is Tareth and Landorl's maps to shoe mid range detail. Then I took Hapimeses city and Simonutp's tower to show smaller scale stuff and then I added some more tokens at human scale.
Link to Video
Most players should be able to play this but if you have issues then I would recommend VLC. Oh and there is no sound on it.
For those interested it was made with CamStudio and MediaCoder.
