Looks like minecraft lego Peter Gabriel out of hand.

Cheap equipment. Ive seen even low-end GIS projects using much better kit that produced extraordinarily good 3d renderings of buildings.

(unless this IS a minecraft thing!)

Looks like someone ate Lego, and then vomited Minecraft.

Pft. I've made better things out of Technix.

How does the laser see the pillars in the buildings and underneath trees?

The problem there is probably the rendering, not the data as such. Better software could probably smooth out the lego look.

It can see through glass and other transparent materials, depending on the wavelength used. However, the amount of light coming back through glass (it has to pass through twice), water, leaves, cloth, etc. is limited. In that image, it can see into the Central Bank through the glass, but can't pick up detail.

Maybe I'm being a bit too literal when I see aerial but if the laser is pointing straight down how does it see around the roof of the building and show empty space in-between the pillars?

If he's just using the laser from an elevated position it makes sense. But that's not aerial damnit!

Are you talking about the Bank of Ireland building? The columns are external. http://www.google.ie/images?hl=en&q=bank%20of%20ireland%20college%20green&um=1&ie=UTF-8&source=og&sa=N&tab=wi&biw=800&bih=411

I don't know what they used for the Dublin image, but look at the image of the paraplane on the wiki link I gave. You can stick the sensor on anything. The first I heard of LIDAR sensors was them being on naval patrol planes looking for shallow submarines and mines.

Where's the rest of it?

This is going to sound pedantic but an aerial shot from above shouldn't be able to see the columns as they are under the roof. But that's just me assuming by aerial he means straight down.
