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!
Por motivos que tampoco viene al caso, he de hacer esto mismo de vez en cuando en todos los Institutos cartográficos del mundo y el del CNIG es sin duda en el que me resulta más fácil, en el que el modelo de datos en más lógico y en el que los links son más fiables de todo el mundo. La única obligación es la atribución obligatoria de los datos. ¿No es mucho pedir, no? Desde el día 27 de diciembre, los datos del IGN son libres CC By 4.0. https://creativecommons.org/licenses/by/4.0/
Por tanto es obligatorio que mencione la procedencia a pie de imagen, créditos, etc.., sobre todo en publicaciones, usos comerciales, artículos, etc… (Por ejemplo puede poner “<tal dato> CC by instituto Geográfico Nacional” o más bien “derivado de <tal dato” CC by ign.es” o similares…).
Ya sea porque necesitemos las imágenes del PNOA (Plan Nacional de Ortofotografía Aérea), un modelo digital del terreno de alta resolución o imágenes históricas de nuestro pueblo… tan solo hay que bucear un poco en el catálogo de geodatos del Instituto Geográfico Nacional (Centro Nacional de Información Geográfica) y los conseguiremos.
Por ejemplo, la semana pasada tuve que encontrar datos sobre algunas ciudades españolas para hacer varios escenarios 3D para un cliente y aquí encontré por un lado un DSM 5m elaborado con fuentes LIDAR, por otro lado me bajé de Cartociudad los datos relativos a vectores lineales, manzanas y luego desde la web de CATASTRO (https://www.sedecatastro.gob.es/OVCFrames.aspx?TIPO=TIT&a=masiv) me bajé las geometrías de todos los edificios de la ciudad (que planeo geoprocesar para eliminar las formas no deseadas y para adjudicar alturas precisas gracias al LIDAR bajado con anterioridad).
Por qué no añadir geometrías de Open Street Maps (https://www.openstreetmap.org/export) o de la propia Base Topográfica Nacional BTN25 para completar dicho escenario?
La verdad amigos es que desde que empezó a funcionar el Open Data, los Geógrafos y derivados tenemos mucho con lo que ‘jugar’ para hacer nuestros análisis. http://idee.es/
Espero que os resulte interesante.

Absolutely ashamed by my government’s insane policies on this regards, Spain is now (…) attempting to scale back the use of solar panels – the use of which they have encouraged and subsidized over the last decade – by imposing a tax on those who use the panels. The intention is clearly to scare taxpayers into connecting to the grid in order to be taxed. The tax, however, will make it economically unfeasible for residents to produce their own energy: it will be cheaper to keep buying energy from current providers. And that is exactly the point. (…)
While we see anywhere else in the world this is being encouraged we don’t, we do exactly the opposite… but if you wonder why this could happen in a allegedly developed country like mine i herewith let you know the reason why… not to compete with other energies or more exactly other big companies providing that energy. A shame or even more than that, a fu***** shame.
So you encourage sustainability and now you discourage it?. In a country like Spain with such an incredible unemployment rate, which slowly reduces this figures at the expense of lower wages, winning competitiveness but losing anywhere else!!! (Mostly if we have cities with +3000 hours of sunshine a year!)
Anyway, trying not to get too upset after writing this words and also trying to make this makes sense in a GIS blog i will try to show you how Lon Angeles county in the US is encouraging the installation of solar panels, ranking all 2010 parcels according to wattHours per square meter. Isn’t it a politically and technically state of the art approach? Yes in my opinion it is, indeed.
I have already worked as a building cleaner, data capture operator, copywriter, photographer, graphic designer, video editor, technical salesman… and seriously, I think i’m too old to make a living in something else now…
GIS has been working for me the last 8 years and i want to stay like this!!!:-) I have just read in GISLOUNGE that Visualization is among a list of a few things which will endure these difficult years of CRISIS.
(…) Visualization Look at the Foursquare time machine for example. The classic cartography is being challenged to new methods. The market wants more beautifully visualized maps. (…)
And if the market needs more beautifully visualized maps, Alberto will be there!!!!.
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 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.
And now, Let’s go to Google Earth!
(I have modified my kml using a extruded placemark we talked about a few posts ago).
Now Let’s have our business in 3D!!!!!!!!!!!!!!!.
Hope you like it.

I have just read a very interesting item of news. WHITEVOID has just released a 3D visualization engine for monitoring more than 16.000 Lufthansa airplanes in realtime… amazing, isn’t it?.
You can navigate throughout the world in a 3D 14 meters screen (!) while you filter content and adjust size, speed and any other parameter…
In addition there’s a 3D audio system that helps you to be absolutely involved in the scenario… I’d love to handle one of those…
Just come back from Chile, Peru and Colombia, where my employer held some conferences on Smart Cities. I had the chance to talk in both venues: GIS expertise, geoprocessing, spatial analysis, etc. This is all about GIS, as always lately 😉 Our Smart City conferences and workshops held this month have been a great success!

Oh! a must see: BGS Geology of Britain. Source from http://www.bgs.ac.uk/discoveringGeology/geologyOfBritain/home.html Britain is fortunate in possessing a remarkably varied geology within a relatively small area. The rocks that make up our islands represent a long and complicated history of events. They encompass most of the major periods of geological time […]
