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.

More of my 3D video edited scenarios.

2009/08/16

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!.

Now Let’s have our business in 3D!!!!!!!!!!!!!!!.

News: Amazing Helsinki 3D!

2009/08/13

Navigating all over the world within Google Earth I have just discovered a brand new 3d layer in Helsinki, Finland.  Almost every building around makes this scenario very realistic… You just have to click on ‘3d buildings’  and it will show you this incredible layer… Does anybody know a WMS map to use it here?.

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.

LEYENDA_CORINE

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

chiclana01

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.

 chiclana02

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

chiclana03

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)…

More geographic post to come very soon!!!

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!.

Map Services. Life and death of GEOAIM.

2009/01/30

We started thinking  about this project on March 2007 after myself and two of my Master’s colleagues noticed we had three different profiles we could combine and build a GIS company… This way GEOAIM gave birth.

A BA Biologist, a BA Environmentalist and a BA Geographer, three GIS and Remote Sensing Master’s degrees (MSc) a Multimedia designer, contacts and lots of hope…

We first developed a GEOTOOL to geolocalize those cranes used to clean high buildings (‘pérgolas’ in spanish), we served them inside a map  and show them to everybody that could be interested in that…

geoaim_buscadoresd

We had a bunch of visits in less than one month!!!. Uau!.

geoaim02

From all over the world!!. Well, from Europe and the USA mainly 🙂

We were awarded with a sponsorship of 30.000 € by the Basque Government  (as one of us was a basque citizen) but we couldnt barely take advantage of it… We split (!) as a result of a personal crisis of one of the members of the company… SHAME!!!… But anyway, it was definitely worth it…

geoaim2

Two of us keep on being friends and there is no place for personal crisis (we are still very young!!!, hahaha) and we could likely start a new project in the future or simply keep on being friends and keeping on sharing a few beers while we watch a rugby game or whatever…

This is the (short) story of a small company that never saw the light but was definitely very interesting as a life experience!… Hey mates, GIS is not just professional stuff, sometimes it’s part of LIFE.
