Taxing the sun?. Yes, in Spain this seems to be possible.
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 taxpayersContinue reading “Taxing the sun?. Yes, in Spain this seems to be possible.”
DTM validation using Google Earth (and RMSE extraction)
Hi guys, Surfing the internet is great when you need to figure out something. I needed to validate some DTM from unknown sources against an also unknown source (but at least a kind of reliable one, Google Earth).

‘Reality Checks’, also called ‘Ground Truth Tests’
Comparing all kind of Geodata (i.e 3D Buildings, DTM, DHM, DSM, Land Use, vectors,…) to background sources as Google Earth/ Bing, available sources from the country we are working on or WMS available sources, etc. Figuring out if the data requested and we want to deliver is consistent enough compared to the so called “Truth”. SomeContinue reading “‘Reality Checks’, also called ‘Ground Truth Tests’”
RSME comparing LIDAR data with a third party’s 3D dataset
I would like to share with you an easy analysis i have been working in the last days. I had a vector dataset of buildings and i knew how high they were (there was a field called ‘AGL’ or Above Ground Level) and a LIDAR 2m resolution dataset over the city of London. My aimContinue reading “RSME comparing LIDAR data with a third party’s 3D dataset”
PISA report SPAIN 2012 by Comunidades Autónomas Trends North-South and West-East
I wanted to take advantage of the latest ‘advanced course on Statistical Analysis’ followed in the spanish IGN and show you how North-South and West-East trends impact on this report. As you can see, the higher the values, the most likely to be in the North and the East of the country. This doesn’t meanContinue reading “PISA report SPAIN 2012 by Comunidades Autónomas Trends North-South and West-East”
