Hair in camera

[davekmrhys]

I think i found a hair on the lens?
I doubt it is a hose pipe.Are there any others or even the same hair picture somewhere else in GE.

I think that this probably actually is a hosepipe - look at the way it follows the contour of the roof and fence.

Also, when you think about it, if there actually was a 'hair on the lens' of a satellite camera, given the enormous focal lengths involved, the hair would appear absolutely gigantic on the image.

[davekmrhys]

I first thought that given that it goes to what looks like a paddling pool but unless the 'hosepipe' is really blurred it is about 150mm wide, if you measure something nearby that is of a known size such as a ridge tile 200mm wide it seems to scale it to the size of a soil pipe which although not impossible, i feel doubtful. Unless someone has any other ideas about what it could be. Also if it was on the sat it would a,probably be invisible b,would be duplicated all over the world! maybe a 20mm pipe can blurr from that altitude. Also most hosepipes i have seen are yellow/green not white also the yellow could have been sun bleached as well. I wish it was a hair on a sat but i agree , doubtful....... :spin:

Its definatley a hair... or bit of cotton or such like. There must be hundreds of hoses strewn across peoples gardens but they are just to thin to see (from space). And why would it go over the roof, over the fence, into the road, then back over the fence.... surely it would have jst gone round the house.

I have seen other pictures with dirt and dust on the lens (Cant remember which ones).. as soon as I see another... will post it here.

STOP PRESS ! In fact.... look slightly south west on the grave yard... there is a line of trees that has quite a few bits of dust n stuff on the lens. There are imperfections all over that area. Have a good look round it.

Knew it wouldnt be long until I saw another... the next link I looked at after this.. and whadaya know... more dirty lenses.

a very dusty camera lens !

a very dusty camera lens !


ahhhh google earth is beautiful. ;)

[memmetch]

I wonder if its a scratch?

[davekmrhys]

I wonder how much there is and more importantly is the same bit repeated anywhere else??????? :confused:

[Smelly Bob]

That is a hosepipe because it's my house ;)

[abkebab]

Why is the hosepipe laying on the roof of the house

a new hair ?? see attachment



:whoa: :lol:

Hi,

Most of the British high resolution coverage in GE is created by aerial photography (from an aeroplane) using film cameras. Separate images will then be scanned and rectified and mosaicked to form large mosaic (called ortho photo).

Dust appear in scanning process - not in the film camera. It is quite a common problem in aerial photo scanning and film handling. Usually film scanners are operated in very clean environment but sometimes dust cannot be avoided.

Dust can later be removed using image processing (e.g. using clone tool of Photoshop).

I hope this clarifies

How big is that pipe and is there any reason why it hung that way. Just curious!, and it still doesn't explain the other 'hosepipes' in the graveyard and in germany! Maybe people are leaving 'hosepipes' everywhere.And people moan about cigarette butts on the floor! ;)

Another long hair in Germany

and another since update

It can't be dust on the lense because it should be seen in several areas with same shape ( e.g the two hair posts in the neighbouring areas ) should be seen at least in one more ( if not in several images ) imagery.

Since the spaceborne cameras use scanning it can't be a 'hair' on sensor.. it has to be on the lense. But then why is it not repeating anywhere else?

Satellites may be put together in clean rooms, GE definitly is not. Or else we have a stowaway zipping over our heads:

If you go back a few posts, "hartrok" explains it very well.

[Ravenfeather]

Somewhere out there, there is a giant, burly Italian man shedding his hairs as he runs across the world... ;)
But seriously, the aeroplane theory seems to justify the subject enough...

[SSSALVI]

I was not aware that aircraft images are also used in GE.

In that case Hartrok's reply is the only possibility.

[Evil_Wreck]

i wonder how google would allow their camera to be scratched. also, there is no hair in space, and people could not have left some hair on the lens (blown away after launch).
Hope this is a valid theory! :hair:

[Munden]

Firstly, Google Earth has no camera. They purchase imagery. They do not 'run' any satelllites or aircraft of their own.

It's also been stated fairly clearly that the imagery being discussed was AERIAL photography.

Finally, there is some sort of confusion that the dust is on the lense of the camera. No, the dust and hair is on the FILM, through the process of developing or scanning. THAT is why there is not a repitition of the hairs. That is also precisely how the bug got into the imagery in Germany. It was traped against the film when it was being scanned into digital data.
