The Science behind Google Earth

The Science behind Google Earth | Teachers Toolbox | Scoop.it

"Google is using a new technology to automatically generate  3D buildings from 45-degree angle aerial photography made by overlapping passes of aircraft.  The aerial photos are combined to create 3D models."

Tecnología para generar imágenes en 3D con Google Earth

Sid McIntyre-DeLaMelena's curator insight, May 29, 2:06 PM

Google Earth has made the Earth easier to decipher and examine in a geographical sense of location and place by being able to see multiple layers. This article goes into the 3D designs and usage of aerial photography to create 3D images.

2012 Election Cartograms

2012 Election Cartograms | Teachers Toolbox | Scoop.it

I'm sure most of you have seen the 2008 version of these fantastic maps and cartograms and they've been a go-to reference for me since the last election.  The typical red state/blue state map conceals much concerning the spatial voting patterns in the United States and fails to account for the population densities of these distributions.  That's what makes this county level voting maps and cartograms so valuable.  

 

Questions to Ponder: What new patterns can you see in the county map that you couldn't see in the state map?  What do the cartograms tell you about the United States population?

A Crazy But Rational Solution To Our Electoral College Problem

A Crazy But Rational Solution To Our Electoral College Problem | Teachers Toolbox | Scoop.it
On three different occasions, the candidate with the most votes didn't become President of the United States. We call this "The Electoral College Problem." Here a solution. Simple. Mathematical. Rational.

Interesting idea but I don't think either political parties will go for it unless it favors them. However, I am not in favor of increasing the number of House Reps. We spend too much money as it is funding the government. I think we should get rid of the old system and simply go by popular vote.

I know the founding fathers would be horrified as this cuts into the whole idea of the electoral college: to place a further check on the majority when electing a president. Nonetheless, I would support a redrawing of the map that would lean toward a popular vote system.

Interesting idea, however I can't say this is a "rational" solution to the Electoral College. It is actually completely irrational to think that the borders could be redrawn and everyone could be redistricted every four years... They can't even manage to get a census out every year... Logistical nightmare. I agree with Ken and Gary, let the people choose with the popular vote
