Modelling Madrid 3D. Geovisualization live!

2009/07/29

And now, Let’s start with a 3D model… this is not very simple thou…

First of all we have a flat /2D scenary at GE, no much more than 50 cm of resolution. The place is very close to Madrid downtown, a very big neighborhood called Moratalaz…we will find there two very big towers of about 50 meters high:

torres01

As I said in the last post now we first open SU (Sketch-up by Google) and click on ‘get current view‘… This is more or less what we will find:

torres02

Let’s start modelling…I’m not telling you here the way you should model it… I’m just telling you that It is a PIECE OF CAKE!!!!!!!… This model has thousands of pieces but I just spent about 15 hours in modelling them all…

I have used something called ‘components‘… this means that you -for instance- design a floor and later on you can repeat it as much as you want… all you change in that floor will be repeated in the rest of them… didn’t I tell you that it was EASY???… Let’s stop saying nonsense and check it out!

Now let’s texture it!. As this is not an architectural model, this is just a building we want to visualize in our 3D scenery (now you know something else about geovisualization, nothing to do with Architecture as you can deduce from it)… we have just used a few textures (less than 5, more than 2…a few! I told you!).

Now that we have just added textures all we have to do is clicking on ‘place model‘ in our SU:

And finally switching to our GE to check it out…

Exactly georreferenced at 40°24’21.08″ N – 3°37’30.22″ W…

Do you like it?. It’s not that difficult isn’t it?. Do you dare to do something similar in your country… I’m sure yes!.

Modeling from scratch. Geovisualization live!

2009/07/29

This is what we first have, a low resolution image taken from Google Earth (GE) visualization engine. This area is a small town within La Rioja, NE of Spain, about 300 km from Madrid. The town is called Muro en Cameros.

First of all we have to find a better resolution imagen beacouse is absolutely impossible geting the shapes of the buildings without a better one… I find it in the SIGPAC website (you can find a link by your right side->).

MuroEnCameros

Let’s see the difference between these two scenaries…

After:

Now, Let’s start modelling!!!!!. We open our Google Sketch-up (SU)…

muroencameros_03

We should clic on this icon to get our current GE view… Very easy as you can see…

Now let’s start modelling… Isn’t it easy?????.

we will check it very soon!
