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.

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!!.

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!

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?.

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)…

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!.

Madrid 3D Virtual Scenario. Geovisualization live!

2009/03/12

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.

Movie6.avi_00-00-15-36

Movie5.avi_00-00-01-06

I connected it to a Database via ARCDSE… Among all featured layers I could find underground stations, information signs,  districts, roads and so on…

Movie8.avi_00-00-03-02

Movie7.avi_00-00-14-29

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!.

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…

tarjetas_alberto

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.
