Softening the blow of complex Geodata. Striving ourselves to ease up the understanding and trying to make easier those complex procedures we usually get stuck in!

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!.
I started modelling 3D buildings quite a few years ago, I used to use 3D StudioMAX… After almost forgetting everything i knew about modelling, 3D and so on Sketch up was released by Google. In a few days i was not just making demos but working and producing!!! Its extremly easy!!!!. Now They have just released something called “Google Earth 3D Building Maker” and its amazing, theres no need to know anything about modelling, you just have to insert polygons and move vertexes…very intuitive indeed!.
place the number of polygons you need…move their vertexes to the proper position.
Directly upload it to your Google 3D warehouse…
And finally take a look at it inside Google Earth… that’s it!.
You can always use Sketchup to perfect it… but it’s good enough…a piece of cake!
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.

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!!.
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!
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:
Defining XYZ axes, first blocks… just starting dudes!…
Applying textures I had already got from Adobe Photoshop…
And after a few minutes modelling this is what I finally get:
Hey, It looks like more or less realistic!!!
Third and last step: Let’s go to Google Earth…
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?.

You find a picture you like and convert it to 3D in a few steps:
Step1: Find a picture you like:
Step2: Now Open your Google Earth and go to Tools/Add/Photo:
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!.
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:
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:
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!.

Rich Interface Design (RID) is the best way to work alongside a developer. You don’t have to design and afterwards the developer tries to transform it into code or upside down you dont have to try to understand developer’s code and at the same time doing your best to get a beautiful and outstanding application… with FLEX you guys are working at the same workspace… everything you design is automatically written into code and you can share it with the developer working with you… isn’t it fantastic???…
Let me please show you some examples…
Hope you guys like it.

I used Skyline Software visualization engine to build this scenario. An orthoimage 0,5m resolution and a 30m resolution heights dataset. I found a few models on the internet (creative commons licesed, just for visualization purposes) I modelled a few of them by myself…and I placed them with Terra Explorer Pro.
I connected it to a Database via ARCDSE… Among all featured layers I could find underground stations, information signs, districts, roads and so on…
After a few ‘fogs’ and ‘shadows’ properties this is what we had… You might use it as a ‘built-in’ scenario you share with your clients or whoever you want…maybe you can save a pre-saved sequence in you desired video format (AVI, MPEG, WMV,…) and if you want to go further, you can always edit it with any Video Editor (the one I prefer is Adobe Premiere in combination with Adobe Photoshop and Adobe After Effects–> you can notice I am in love with Adobe)… There are a lot of possibilities, even adding music that has something to do with your scenario… try it!.
Hope you liked it!

Decenas de medios y redes sociales, algunos poco fiables por incapaces o partidistas (o las dos cosas), muchos datos, no necesariamente bien extraídos y analizados, varios criterios no harmonizados y cambiantes (en los últimos días dos veces han cambiado los criterios del Ministerio de Sanidad español!) me convencieron para hacer los análisis yo mismo pero e […]
