Extract Photogrammetry 3D from Google Earth/maps

[Vizioen]

Each version of google maps/earth is just blowing me away. It's been there for a while now but the 3D generated from photogrammetry (I think) is from afar quite amazing.

For instance:



I could really use this terrain and it would save me quite a lot of work as I have a very tight deadline. I have googled quite a bit already but does anybody now how to do it?

The only thing I found was this: https://vimeo.com/41659249

Was also looking for a way to do this recently, trying to get a section of south London. That video is also the only thing I could find...... didnt have time to try it.
So also wondering the same thing, or any other similar resources I guess?

I tried, it but it only works with older versions of Google Earth and Max. And the older versions only include the 3D geometry drawn by users not generated by photogrammetry. It's weird there's no tool for this yet Or Google just protected themselves very good

yes i discovered the same. thre are a couple of ways to grab geometry from google earth, one for opengl , one using directx, and both basically taking a grab of what is in the gpu memory and writing it to disk.

neither of the tools to do this were designed with it in mind, and neither of them are still being updated.

also, as Vizioen says, they only work ( if at all, i had very little success) with specific older versions of google earth, which do not stream the latest geometry.

and i agree, its very odd that nobody has cracked this yet.

I guess it's oldschool modelling then untill someone comes up with a nifty hack

Yeah I used to use it a lot and that 3Dxripper thang is dead You can still download some of the old google earth models if you're lucky but a lot of them now can't be...

I was looking to do the exact same thing few weeks ago and couldn't found anything else than that video, but it looked too old to be still relevant so I didn't investigate more.
Plus I found that Apple maps is way waaaay more advanced than Gmap in terms of 3D buildings.
But I didn't found any way to extract data from apple maps either. :/

If anyone has any clue how to do so, I'd love to hear.

Well I don't own any kind of Apple device (except for the old Macbook Pro that keeps my window open), and it seems it's only available through an app of some sorts. If there's a website where I could see/test this I would be glad to. I don't see the upside to having it only in an app. (only for Apple's wallet). At least good old google provides it free for everybody.

Not sure if it would work, I have not had a chance to test it at all, but it is far newer than DXRipper.

i tried ninja ripper.. didnt work. not that this means somebody else might not have more luck.

[Vizioen]

Same here.

I've been trying to do this myself without success, so I'm just subscribing to the thread in case someone finds a way eventually
I'm guessing it would probably not be legal to do it in any case, but it would be so nice to be able to use it, even just as reference for building new models over it, these are most likely very "dirty".
BTW, these models are also available on google maps in your browser, not just google earth. I'm not sure what tech browsers use to display 3d, though... I think this is also a huge issue with Sketchfab, those models can probably be ripped easily.

Is there a service to get relatively accurate data as far as building footprint dimentions and such? Ive been trying to find such a thing for the downtown core in my city but no such luck, and have found the measurement tool for google earth is very unreliable.

I recently used Pictometry (http://www.eagleview.com/Products/Im...ryImagery.aspx) to take some basic measurements on existing structures and it worked pretty well. Interesting thing is that you can even take vertical measurements as well. I was borrowing a colleagues license since I only needed a few measurements so I'm not sure on the pricing (I think it's not that cheap though as you need to subscribe to the service rather than just paying for it when you need it).

Yea this is for a personal project so I was hoping for a free solution lol
