Image Analysis

Image Analysis | Spatial in Schools | 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 as the year in United States history as the year with the most acrec 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.

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.

Markus Reugels is a German photographer who specializes in capturing the art of water droplets.  The resulting images are so fantastic one might think that Photoshop or some other image manipulation software had a hand in creating them.

 

As beautiful image as you'll see anywhere.

Much like sites that you can rate items up or down, you can rate the best aerial photography via Google Earth screen shots. There are some beautiful images and places to be discovered through this site. The physical and human landscapes are both intermingled in this fantastic collection of images…be careful, it can be amazingly addictive.   One this blog post I've added 13 of my favorite cultural and physical landscapes on to http://www.stratocam.com

These satellite images are truly spectacular! They are beautiful and, yes, addicting to look at! I found it interesting that the images of manmade cities/landscapes had similar design and curvature to the images of Mother Nature's oceans and forestry.

Visually on a ground level it is hard to conceptualize the significance of the surrounding landscape. How people alter our surroundings can reveal a lot about the history and culture of a particular society. Although the architecture at Vlagtwedde in the Netherlands is quite stunning from an aerial view, this fortress was designed to repel invaders and control the area. Even if you don’t know much about this country’s history, this image reveals that it was most likely not a peaceful place in the 16th and 17th century.

St. Augustine hit this saying out of the ball park. Sometimes when I try taking picutres of the sky or of a scene, I will delete the picture because it just isnt the same as in realy life. I really think that traveling gives people a reality shock when seeing new phenomena.

What i think this quote means is that you may think you know a lot about the world but until you go and travel to different places you will not fully understand the world. I also think it means that there is so many different things to experience on earth.

For the wanderlust in all of us.
