Google Earth Community: 3D Building Quartier de La Madeleine

Hi Keith!

First of all thanks for the nice comments, we are always glad to know that our work please others!

I use to say that our work, differently from what I have seen at G.E. so far, has a different use and meaning: we literally rebuild existing buildings up to the last detail using a technique called terrestrial photogrammetry . Terrestrial photogrammetry is a group of topographic, geographic, photographic and computer techniques used to reproduce at scale and with details virtually every building on Earth. We depart from digitalizing pictures (alternatively laser-scans that we don't use due to heavy post-work, large output database, lack of necessary precision, costs, etc), then transforming them into a 3D CAD model (in our case AutoCAD). From there our work is delivered to our traditional customers: architects in restoration/rehabilitation projects; real state managers, public cadastre, real state owners, etc.

Complementary to our work we have developed software to export our database (and eventually from others) to Google Earth. One particularity of our system is how it handles surfaces: with no triangulation, we can handle ANY element from AutoCAD and compress it largely (the original database from which models come are huge due to its highly detailed renderings), creating very light files for the amount of details we provide.

Our target is, as it has always been, to work with clients who need highly detailed, correctly scaled 3D models. For example, an architect rebuilding a historical monument, a department in a real state company who needs to manage their facilities, etc. The advantage is that we can deliver much more in terms of precision and details from what has been done so far.

We have been comissioned to do some buildings in Paris (AXA head office, Louis Vuitton building, Georges V Hotel, GDF head office and several smaller ones) and even whole city centres or parts of it, such as Cagliari or Versailles among others. Not the Louvre yet, although we'd love to be comissioned to do it in the scale 1:50, rendered with every detail.

What we are looking now is how to couple with other systems, bringing our precision and detail to Google Earth in a way that we haven't seen so far. We are also looking for new customers for our terrestrial photogrammetry projects… and we are always open to consider partnerships, new venture developments in software, or so

; Who knows if Google or AutoCAD don't look at us and see what we have in special here!

There's a whole world to be built, literally, there's space and work for everyone!

Thanks for your comments and I hope it has helped to solve some of your questions.

Cheers
