I love these favela images by Fernando Alan.

These images of the favelas are both breathtaking and heartbreaking. Breathtaking in the sense that these aerial images show the scale of the entire neighborhood. You begin to get an appreciation for how large these favelas actually are. The amount of people living in this area is remarkable. The image is also extremely heartbreaking. I can only imagine the everyday problems and issue that the residents of these slums face. In the nations so called festive city, I see little reason for these people to celebrate. These are the forgotten people of the brazilin economic boom. They are the ones who the government would not like anyone to know about. Sadness and aw some up my reaction to this photo.

Just seeing images like this make me feel sad that there are people out there living the way they do. Favelas can be defined as the "slums" or ghettos. Favelas are built on hillsides and they tend to have very poor history with the police. Since the favelas are considered to be the slum area, the government provides very little assistance, and if you were to visit the favelas, you could find for example some very poor and dangerous wiring from the local people wire-tapping.

This is an incredible favela village in South America. It shows how densely the population of slums are and how they are built up on the hillside. Most favelas are built on the side if the hills which are the most unstable portions because they can't afford to have a better place in the valley and away from the mudslide and avalanche areas. Great depiction of the slums.

The True Size Of Africa

The True Size Of Africa | Educació de Qualitat i TICs | Scoop.it

This is another old classic image that I might have shared earlier but it merits repeating. As Salvatore Natoli (a leader in geography education) once said, "In our society we unconsciously equate size with importance and even power." This is one reason why many people have underestimated the true size of Africa relative to places that they view as more important or more powerful.

Just a reminder

Edelin Espino's curator insight, December 5, 2014 11:01 AM

It is incredible big, but unfortunately most of the north area is cover by the big Sahara and most of the are is typically unfertilized. 

Jason Schneider's curator insight, March 9, 2015 4:29 PM

As we can see, there's a little overlapping here and some empty spots but it's pretty accurate. The United States and China are in the top 5 largest countries of the world list and they still fit in the 2nd largest continent of the world, Africa. I'd like to see the size comparison between Africa and Russia. I did some research on that and it turns out that Russia is a little over half the size of Africa, maybe the size of the combination of the United States and China.

Image Analysis

Image Analysis | Educació de Qualitat i TICs | Scoop.it
One of a number of large wildfires that have affected northern California in 2012, the Chips fire burned more than 75,000 acres by the time firefighters had contained it.

 

2012 is going to go down in United States history as the year with the most acres burned in a single year (statistics only go back to 1960).  The two featured images were taken earlier this month to display a Northern California wildfire; both with the same spatial resolution and acquired for the same instrument (Advanced Land Imager on EO-1 satellite), yet they are quite distinct.  One shows an aerial photograph, displaying exactly what standard visible portion of the electromagnetic spectrum (showing us what our eyes would normally see).  The other image displays a false color (near infrared) image. 

 

Questions to ponder: what advantages does each image have for analyzing the fire damage?  Drawbacks?  How does the data from both images work together to create a more complete picture of the situation?

The first image displays a better visual of exactly where the fire damaged the land, the second image doesn't provide a clear visual to someone, the land effected is foggy. If I was going to visit this specific area in Northern California I would much rather use the first aerial image.
Jesse Gauthier's comment, September 17, 2012 10:31 AM
The first image gives a good spatial shot of where the exact hot spots are located that cannot be seen by the naked eye. The second photo will give you a spatial view of what you can actually see. Both are needed to put out the hot spot because they each will provide two different solutions to stop the burning acres.
