Cool data. What is this?

2013/09/16

cool-data

What is this ‘cool data‘ all about?. When i got my degree in Geography (about 15 years ago) it didn’t make sense at all being interested in something like graphic design, photography, video and all this stuff… but not only interested in my leisure time but also for taking advantage of it, getting a life out of it. When, after three years of working in a plane while taking aerial pictures i got fed up with anything related to Geography (and working 24/7) and started working as a website designer it started making a bit of sense… Only five years later, having worked as multimedia photographer, graphic designer and technical salesman everything got aligned and made all the sense in the world… i wanted to come back to Geography but taking advantage of all this years of doing something else…

It was time to resign and comeback to the university to get a MSc (In Remote Sensing and GIS)… leave everything behind and planning my working life again. After finishing my master’s degree (well, actually they were two!) i received a call from South Africa. Are you Alberto?. Hell yes, I am!. We have just received your CV and we are interested in offering you a job dealing with something (i didnt know about) called ‘Geovisualization’. Again, what is this all about?. Well, its dulcifying, easying up all complex information and offering it in a new way, a much easier way to understand it… This is what i call COOL DATA.

Let’s imagine there’s something our customer doesn’t really understand and its kind of difficult to describe using words… There’s always a way for making it easier. Using Graphic design tools or Video software to recreate a workflow or explain something complex… even adding some music, why not???.

cooldata01

Using Photoshop Macros and a few composition rules we can convert a tricky template in something we, our team and our customer will understand completely.  What about Global Mapper scripts for quick conversions between formats?.

cooldata02

What about including some statistics?

cooldata03

and Spatial analysis?.

cooldata04

And 3D?

cooldata05

Maybe some video?

Is this clear enough?. No?.
Let me explain it to you in English, French or Spanish.

Now, seriously, count on me in case of need of converting complex datasets into COOL DATA.
Please don’t hesitate to contact me.

Solar + Shadows analysis on Rue Massillon, Nantes (France)

2013/04/04

This is the beautiful building in from of my house in Nantes… Let’s model it first using Sketchup. Also i have used a non standard style only for visualization purposes…

rue_massillon_02

If we have the North behind us this means we are going to have a lot of light… but so far we are just guessing…

rue_massillon_01

Now we know if for sure. Take a look at the results by M. Capeluto’s Solar Analysis.

rue_massillon_03

If we face South we notice there’s a lot of sun in the other side of the building (every line is a summarized path during a month, being the higher the closer to the summer solstice)

Please take a look at the video prepared by Tomasz Janiak, the developer of the tool.

Hope you guys find it interesting. Please let me know your thoughts.

Some of my 3D scenarios

2009/08/16

Barcelona (Spain), Winnipeg (Canada), Las Vegas (USA), Moscow (Russia), Durban (South Africa), Vancouver (Canada) and Tokyo (Japan)… these were some of my Terrain view’s 3D scenarios published by Computamaps, a South African company I worked in not so long ago. By the way it was one of my best professional experiences ever… I enjoyed joining them a lot and It was very difficult leaving them (mainly because of Cynthia’s fruit salads;-)… Miss you guys a lot!!!

Hope you liked them.

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.

Creating and personalizing KML code (placemarks).

2009/08/11

First of all, what is KML?. KML is a file format used to display geographic data in an Earth browser, such as Google Earth, Google Maps, and Google Maps for mobile. You can create KML files to pinpoint locations, add image overlays, and expose rich data in new ways. KML is an international standard maintained by the Open Geospatial Consortium, Inc. (OGC). You can choose wether authoring directly from Google Earth itself or you can try to understand the code and doing it by yourself… You can draw placemarks (using descriptive HTML to personalize them), ground overlays, paths, polygons… Let’s start with the placemark:

-> Simple placemark

<?xml version=”1.0″ encoding=”UTF-8″?>
<kml xmlns=”http://www.opengis.net/kml/2.2″&gt;
  <Placemark>
    <name>Simple placemark</name>
    <description>Attached to the ground. Intelligently places itself
       at the height of the underlying terrain.</description>
    <Point>
      <coordinates>-122.0822035425683,37.42228990140251,0</coordinates>
    </Point>
  </Placemark>
</kml>

simpleplacemark

  • An XML header. This is line 1 in every KML file. No spaces or other characters can appear before this line.
  • A KML namespace declaration. This is line 2 in every KML 2.2 file.
  • A Placemark object that contains the following elements:
    • A name that is used as the label for the Placemark
    • A description that appears in the “balloon” attached to the Placemark
    • A Point that specifies the position of the Placemark on the Earth’s surface (longitude, latitude, and optional altitude)
  • -> Floating placemark

    If instead of regular <description>

    <description>Attached to the ground. Intelligently places itself
           at the height of the underlying terrain.</description>

    simple

    you use the CDATA element, you can write HTML and avoiding Google Earth from parsing the code incorrectly:

     <description>
            <![CDATA[
              <h1>CDATA Tags are useful!</h1>
              <p><font color=”red”>Text is <i>more readable</i> and
              <b>easier to write</b> when you can avoid using entity
              references.</font></p>
            ]]>
          </description>

    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?.

    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)…

    chiclana04

    More geographic post to come very soon!!!
