Five Tips and Strategies on How to Interpret a Satellite Image

Five Tips and Strategies on How to Interpret a Satellite Image | Geography Education | Scoop.it
What do you do when presented with a new satellite image? Here's what the Earth Observatory team does to understand the view.
  1. Look for a scale
  2. Look for patterns, shapes, and textures
  3. Define the colors (including shadows)
  4. Find north
  5. Consider your prior knowledge
Seth Dixon's insight:

Aerial photography can be quite beautiful, as can satellite imagery. These are more than just pretty pictures; interpreting aerial photography and satellite imagery is not easy; here is a great article that gives an introduction on how to interpret satellite imagery. With a little training, satellite images become rich data sources (instead of some visually meaningless data).  Using Stratocam, you can explore and tag some of the amazing place on Earth.

Choosing a Map Projection

"Cartographers at National Geographic discuss how they select an appropriate map projection for the September 2012 magazine map supplement. --World maps usually center on the land, with the Pacific Ocean divided as bookends. To show each ocean as a whole with the least distortion for our 'Beneath the Oceans' supplement map, we used a map projection called an interrupted Mollweide centered on the Pacific."

Seth Dixon's insight:

There is no one perfect map projection that fits all circumstances and situations. Think of a situation in which this map projection would be an ideal way to represent the Earth and in another situation that same projection would give you an incredibly limited perspective.  This video provides good insight into how to choose a map projection for a cartographic project. Here is National Geographic's lesson using this video.

Speaking the “Language” of Spatial Analysis

Speaking the “Language” of Spatial Analysis | Geography Education | Scoop.it

"Spatial analysis has always been a hallmark of GIS, the 'numerical recipes' which set GIS apart from other forms of computerized visualization and information management. With GIS we pose questions and derive results using a wide array of analytical tools to help us understand and compare places, determine how places are related, find the best locations and paths, detect and quantify patterns, and even to make spatial predictions."

Seth Dixon's insight:

GIS is a key tool in spatial analysis, but it can also be a driving force in using math, science, technology and (yes) geography as interdisciplinary ways of teaching the curriculum.  StoryMaps can be rich with images and videos, but also filled with data at a variety of scales.  ESRI has share a "Maps we love" page with excellent examples of Story Maps and carefully explains WHY these maps work and HOW they were made.  Are you new to using the Analysis tool in ArcGIS Online?  Try this exercise on analyzing flood risk to guide you through some of the steps to learn what is possible for a project of your own.  What stories can you tell in this rich, visual format?  What visual template shown might lend itself best for that sort of project?

All Maps Are Biased. Google Maps’ New Redesign Doesn’t Hide It.

All Maps Are Biased. Google Maps’ New Redesign Doesn’t Hide It. | Geography Education | Scoop.it

"Google rolled out its new Maps design...from a navigational tool to a commercial interface and offers the clearest proof yet that the geographic web—despite its aspirations to universality—is a deeply subjective entity."

Seth Dixon's insight:

Google Maps was updated over the summer, and the updates don't make them more impartial, but that isn't a bad thing.  Google Maps now highlight 'Areas of interest,' which are created with algorithms designed to reveal the “highest concentration of restaurants, bars, and shops.” The algorithms aren't 'objective,' but are fine-tuned by human engineers to reflect what they consider 'Areas of Interests' should look like.  Maps are never as objective as they appear to be, and that can often be a great thing.

LEONARDO WILD's curator insight, September 6, 2016 9:30 AM
All maps are biased because they are not the territory, but represent our subjective view of the territory; what we include and what we leave out depends on what we deem important, or not. Europe is still oversized in most current maps in relation to the "Third World." What is the new politically correct fad?

"If you're heading out on the road for your vacation this year, you'll probably get directions from a GPS or navigational system. Does that mean that the traditional map is a relic of the past? Mark Albert hits the road to find out."

Seth Dixon's insight:

This video is designed for a general news audience and it nicely shows the public how cartography is not rendered unimportant in the era of digital maps, but has become all the more useful.  I could see this video as useful resource to share with parents who are worried that studying geography won't lead to careers.

"The Urban Observatory city comparison app enables you to explore the living fabric of great cities by browsing a variety of cities and themes."

Seth Dixon's insight:

At the 2013 ESRI User Conference, the Urban Observatory was unveiled (I shared this earlier, but the URL has since changed, I'm sharing it again).  The physical display contained images from cities around the world to compare and contrast diverse urban environments.  The online version of this was announced during in a 10 minute talk by Jack Dangermond and Hugh Keegan.  This interactive mapping platform let's users access 'big data' and have it rendered in thematic maps.  These maps cover population patterns, transportation networks, and weather systems.  This is a must see.  Read Forbes' article on the release of Urban Observatory here.

Maya civilization was much vaster than known, thousands of newly discovered structures reveal

Maya civilization was much vaster than known, thousands of newly discovered structures reveal | Geography Education | Scoop.it
Scientists using high-tech, airplane-based lidar mapping tools have discovered tens of thousands of structures constructed by the Maya.

 

Archaeologists have spent more than a century traipsing through the Guatemalan jungle, Indiana Jones-style, searching through dense vegetation to learn what they could about the Maya civilization. Scientists using high-tech, airplane-based lidar mapping tools have discovered tens of thousands of structures constructed by the Maya: defense works, houses, buildings, industrial-size agricultural fields, even new pyramids.

The lidar system fires rapid laser pulses at surfaces and measures how long it takes that light to return to sophisticated measuring equipment. Doing that over and over again lets scientists create a topographical map of sorts. Months of computer modeling allowed the researchers to virtually strip away half a million acres of jungle that has grown over the ruins. What's left is a surprisingly clear picture of how a 10th-century Maya would see the landscape.

Nicole Canova's curator insight, February 9, 8:55 PM
This article is not only about our expanding knowledge of Mayan civilization, although it is fascinating that experts are learning more about the cultural and historical geography of Guatemala.  It also highlights some problems that physical geography can sometimes pose to researchers, and the solutions that are becoming possible because of improving technology.  Archaeologists, rather than hiking through dense forests on the off chance of happening upon something recognizable as an ancient structure, can now use laser imaging to see past the overgrowth.
Kelsey McIntosh's curator insight, February 14, 9:50 PM
This article is particularly interesting because it not only claims to change the way we think of the Mayans, but it also describes the methods used for unearthing the ruins of a civilization that has been lost. By using the Lidar system, archaeologists were able to discover a city with thousands of houses, pyramids and other buildings.
Matt Manish's curator insight, February 16, 1:57 PM
Archaeologists are using new high-tech, airplane-based lidar mapping tools to discover Mayan structures that have gone undetected for hundreds of years. This new method for archaeology has proved very successful as well, since tens of thousands of hidden Mayan structures have been detected using these new tools. This helps paint a different picture of what Mayan civilization was really like. For example, archaeologists now believe that the Mayan civilization may have had a population two to three times the size originally estimated and a much larger extension of land than previously thought. At the end of this article, what really made me think was how the Guatemalan jungle once hindered archaeologists from discovering Mayan structures, but now the jungle is seen as useful in preserving these structures over time, so they are not destroyed by people. It seems as though there is still much to learn about the Mayan civilization and their culture.

A More Accurate World Map Wins Prestigious Japanese Design Award

A More Accurate World Map Wins Prestigious Japanese Design Award | Geography Education | Scoop.it

"To design a map of the world is no easy task. Because maps represent the spherical Earth in 2D form, they cannot help but be distorted, which is why Greenland and Antarctica usually look far more gigantic than they really are, while Africa appears vastly smaller than its true size. The AuthaGraph World Map tries to correct these issues, showing the world closer to how it actually is in all its spherical glory."

Seth Dixon's insight:

This just shows how subjective the concept of "accurate" can be. First off, this is a fabulous map that nicely minimizes distortions (distance, direction, area, and shape) of the land on our planet. Any criticism of the map just shows the impossibility of making an accurate 2D map of a 3D Earth, but I still think that there is plenty of room to discuss the flaws/distortions that were chosen instead of others. It is interesting to note that a Japanese contest awarded this map with it's top honor (I doubt a Brazilian organization would feel the same way about this map). This map does make with some traditional cartographic conventions in its representation of Earth.  

 

Questions to Ponder: What are some elements of this map that are different from more traditional maps? This map claims to be more accurate; does that make it more useful?

The most detailed 3D world model

The most detailed 3D world model | Geography Education | Scoop.it

"How to create a detailed 3D topographic model of the entire Earth? As you could suspect the only feasible way to do it is using satellites. But a regular satellite scan will not be detailed enough to give you a meter-level accuracy. Instead of using a single satellite they’ve launched to an orbit two satellites orbiting next to each other capturing stereoscopic scans of the surface of the Earth (that scan the same areas from slightly different angles). Now this data has been processed into a seamless 3-dimensional world map of unprecedented accuracy of 1 meter. The data and the press release are publicly available."

Petra, Jordan: Huge monument found 'hiding in plain sight'

Petra, Jordan: Huge monument found 'hiding in plain sight' | Geography Education | Scoop.it

"Two archaeologists, who recently published their findings in the American Schools of Oriental Research, used Google Earth satellite images and drone photography to identify the outline of an enormous monument buried beneath sand and time at the UNESCO World Heritage site in Jordan."  --Motherboard

Seth Dixon's insight:

When in the Mexican state of Veracruz as a grad student, I saw a startling mountain covered by the dense tropical rain forest; this mountain had a consistent slope with hard angles.  I was awestruck to realize that it was an uncovered (but not undiscovered) pyramid and I wondered just how many archeological sites are waiting to be unearthed. 

 

Why is a geographer an important member of an interdisciplinary team? This discovery shows that spatial thinking, geographic tools, and a keen eye for usually patterns in unexpected places are critical for many disciplines and fields of research.

(Middle East) Using modern technology, archaeologists have discovered a new monument hidden underground in Petra. The find, dated around 150 B.C., is thought to be a ceremonial site with two platforms, pottery. columns, and a staircase carved out of stone. It is amazing that there are still new finds like this in the 21st century, but the history of the Middle East is so incredibly old, with so many extinct civilizations, that archaeologists will probably keep making new breakthroughs.
