Geovisualization, 3D models and more!

2009/08/17

Here you will be able to see some of my latest 3D stuff… A compilation of 3D models, flythroughs and graphic resuorces available… All you need regarding 3D scenarios (heights datasets, satellite imagery and 3D models) and Video Edition… Are you guys thinking about doing something like this?. Please contact me.

WMS in Google Earth.

2009/08/04

I have thought there is something very interesting maybe you guys have never tried… using your Google Earth sesssion not just for navigating, finding your house or the place you are going on holidays to… If you use the WMS protocol to show your map over your 3D scenario you are going to add a little bit more of interest to your Google Earth… Lets add a Corine Land Cover Map over my 3D map…but, What is WMS???, What is Corine Land Cover???. Im not even trying to tell you by myself, I am opeining my WIKIPEDIA to tell you, hehe…

WMS

A Web Map Service (WMS) is a standard protocol for serving georeferenced map images over the Internet that are generated by a map server using data from a GIS database. The specification was developed and first published by the Open Geospatial Consortium in 1999.

CORINE LAND COVER

CORINE (Coordination of information on the environment) is a European programme initiated in 1985 by the European Commission, aimed at gathering information relating to the environment on certain priority topics for the European Union (air, water, soil, land cover, coastal erosion, biotopes, etc.). Since 1994, the European Environment Agency (EEA) integrated CORINE in its work programme. EEA is responsible for providing objective, timely and targeted information on Europe’s environment.

This is the Official Corine Land Cover key map.

This is the area I would like to know more about, Chiclana de la Frontera in Cádiz, SW of Spain.

This is once we get connected via WMS to the place where you can get those maps (http://www.idee.es/wms/IGN-Corine/IGN-Corine?). By the way you can search on the internet to get more maps… you just have to go to google and search for ‘wms maps’ and you’ll be able to find them. This is a Corine Land Cover Map with information from year 1990.

This is a Corine Land Cover Map with information from year 2000.

This is what we find after comparing both images… I have compared them using Photoshop CSX but you can go further and use global Mapper, ER Mapper or ArcGIS… As you can see, those areas highlighed are the areas with changes (very small in this case)…

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!

Rich Interface Design with Adobe FLEX Builder.

2009/05/27

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…
