Seminario motivacional en el Máster Tecnologías de la Información Geográfica de la UAH

Esta vez me tocó impartir el seminario motivacional “Geógrafos en tiempos de GIS” en el entorno del Máster de Tecnologías de la Información Geográfica. Yo encantado pues este mismo máster lo cursó yo hace ya doce años (wow, time flies, el tiempo pasa rápidamente cómo dicen!) y la verdad es que me encantó hacerlo.

Visualizing Tweets!

How about a quick visualization of tweets in CartoDB? Hey guys, the way we used to visualize is changing on a  daily basis so it’s time to catch up!!!. Let’s add a timestamp and play!! We will take a look at this dataset in depth shortly so be aware of our schedule! Regards, Alberto CONCEJALContinue reading “Visualizing Tweets!”

La geográfica cabecera de ‘Up in the air’ con George Clooney

Para alguien que maneja mapas a diario es una sorpresa interesante cruzarse con esta cabecera de la película de Jason Reirman protagonizada por George Clooney ‘Up in the air’. Nubes, campos de cultivo, ciudades en 2D, 3D. Qué bien he elegido mi profesión:-) Para alguien que viaja mucho, salvando las distancias, este vídeo, también delContinue reading “La geográfica cabecera de ‘Up in the air’ con George Clooney”

Visualization will endure these difficult years of CRISIS!!

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 inContinue reading “Visualization will endure these difficult years of CRISIS!!”

Visualizing LAS LIDAR data with sketch-up

While trying to figure out the way to get a 3D model from raw Lidar data, I first opened my LAS file in Global Mapper, exported it to DXF, imported then into Sketch-up and after recording a few scenes, I saved the animation… this is it!. Alberto

Using Excel to calculate the RMSE for LiDAR vertical ground control points

(source: The height accuracy of the collected LiDAR data can be verified by comparing with independently surveyed ground control points on hard, flat, open surfaces. It is essentially just calculating the height differences for all the control points and then determining the height root mean squared error (RMSE) or differences. Most LiDAR processing software have theContinue reading “Using Excel to calculate the RMSE for LiDAR vertical ground control points”

Data acquisition: How do I know if this river is been well acquired?

I’ve already entered my river but my imagery was in 2D so… was it well acquired?…  First of all, I import my shape (shp) file into Global Mapper (what a great sofware!) and export my vector file as a KML. Import my river.kml file into my brand new Google Earth 5.2 or just double-click itContinue reading “Data acquisition: How do I know if this river is been well acquired?”

GIS+Architectural scenaries. Awesome!

Even from scratch or from dgn/dxf vectorial format’s contour lines you create your own scenario. Then import your model previously created using Sketch-up (this time i used google’s 3d warehouse, thank you Dilbert). Stamp your house using sketch-up sandbox tools. Then fur your scenario as if it was grass… A little of photoshop like clouds andContinue reading “GIS+Architectural scenaries. Awesome!”
