Data acquisition: How do I know if this river is been well acquired?

2010/06/14

I’ve already entered my river but my imagery was in 2D so… was it well acquired?…  First of all, I import my shape (shp) file into Global Mapper (what a great sofware!) and export my vector file as a KML.

Import my river.kml file into my brand new Google Earth 5.2 or just double-click it in his location… easyest impossible!.

Select it and use ‘show elevation profile’,  a very useful new tool for these purposes…

And that’s it, constant altitude, almost perfect!.

Hope you have considered it interesting:-)

Map24.com; My favorite route planner!

2010/06/03

My very good friend Fernando (a spanish/english like friend of mine:-)) introduced me this magnificent route planner he was using at that moment (three years ago!!!!)… map24.com had a very interesting 3D engine, very easy to use and very reliable… I’ve been using it since but it has never been one of the most famous among route planners in the market…

I strongly recommend it and i really like it a lot! enjoy!

Please, dont forget to turn on your speakers. Even if i first used a different score and Youtube’s elfs told me not to use it (because of copyright authoring) I have chosen this music from their stuff and this is what I finally got…

Hope you like it.

One more 3D building. Avenida de la Vega 28108. Restaurante Asiático SHENG. Madrid, Spain.

2009/08/15

I used to have lunch every thrusday there, at the ‘Restaurante Asiático SHENG’. I strongly recommend you ‘entremeses’ (In China you will find them as ‘dim-sum’) and Cantonese duck or Hong Kong duck (this was slightly spicy thou).  Very good food, very fast service and pretty cheap menu: 10,7 €… ideal for an IT worker!.

These views were rendered using ‘V-RAY’ for Sketch-up.

And now, Let’s go to Google Earth!

(I have modified my kml using a extruded placemark we talked about a few posts ago).
Now Let’s have our business in 3D!!!!!!!!!!!!!!!.
Hope you like it.

Getting textures from Google Maps – Street View

2009/08/05

I this post I am trying to show you how easy is adding a building to your scenario using textures from Google Maps (Street View). You have to know a little bit about Photoshop and layers and these stuff but it’s pretty easy thou…

First step, capturing my screen…OMG!!! there’s a tree in the middle of the building I want to model… there is no need to worry about it… Photoshop deals with it very well!!.

vic01_old

vic02_old

vic03_old

And after taking these three pictures I finally get this one (Thank you Photoshop!!!)… I could have done it much better but this is just for you to know the way to do it… its not that bad thou!

vic_lat_def

Second step: Start modelling… Im not teaching you how to model but I can tell you it’s a piece of cake… just try it. Of course I am using my beloved Google Sketchup. I get my current GE’s view:

defi01

Defining XYZ axes, first blocks… just starting dudes!…

defi02

Applying textures I had already got from Adobe Photoshop…

defi03

defi04

And after a few minutes modelling this is what I finally get:

defi05

Hey, It looks like more or less realistic!!!

defi06

Third and last step: Let’s go to Google Earth…

defi07

defi08

These two blocks of buildings are very close to where I live here in Madrid. Vicálvaro is 10 minutes to Madrid downtown by car… It’s far away but now it’s in your computer…cool, isn’t it?.

Georreferenced pictures. Geovisualization live!

2009/08/04

You find a picture you like and convert it to 3D in a few steps:

Step1: Find a picture you like:

arroyo_05

Step2: Now Open your Google Earth and go to Tools/Add/Photo:

Untitled-1 

Untitled-2

Step3: You have it with the same perspective… you can even navigate inside the picture… This is just within a 3D model, now imagine if you have pictures from your trips… you can share their position with your friends just saving these files into a KML!!!… We’ll check it soon!.

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!

torres03

torres04

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!).

torres05

torres06

torres07

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

torres08

And finally switching to our GE to check it out…

torres09

torres10

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.

muroencameros_00

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…

Before:

muroencameros_01

After:

muroencameros_02

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… 

muroencameros_04

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

muroencameros_05

we will check it very soon!
