This is true, we can see and enjoy our immediate surroundings. But I love to look at places on Google Earth that I may never be able to visit, I think it would be amazing to view these places through the high tech lenses that actually exist!
The technologies that exist to create such high tech maps are incredible. I find it sad the the average human will mostly never see the extent of this technology. There are many technologies that already exist that we will never see or hear about. It is to bad that we can't even experience a high quality images of the world we live in. I would find it incredible interesting to view.
Most likely these people did not know what astrology is or just got it mixed up with astronomy. If someone is quickly doing a survey they probably saw "astro" assuming astronomy and went on their way. However, if people actually don't know the different between the two, that is incredible sad. Especially since astronomy is a important field that needs new people entering it.
