Vultures, Environment, and Mapping Trash

"For generations we vultures, armed with our senses, have fought in silence. We’ve waged a battle against garbage, but now we’re losing that battle. We want to help humans, so we’ve launched a movement to help you detect piles of garbage so that you can take action to eliminate them. Join us in this fight. Vultures Warn, you take action!"

Seth Dixon's insight:

This video is an introduction to a fascinating (Spanish language) website and project that uses GPS-tagged vultures to map out the urban trash hot-spots in Lima, Peru.  We look at vultures as the dregs of the food chain and ascribe moral filthiness to the species (just think of any number of movie, literary, and cultural references), but they are simply filling an ecological niche.  This mapping project is a way to use vultures nature in a way that allows for humanity to fix our trash production/disposal problems.

"The president and owner of Mapping Specialists, David Knipfer, said maps are more prevalent in society now than they’ve ever been, from turn-by-turn direction apps, to restaurant searches, to social networks that pinpoint users’ locations. Maps aren’t going away, but people are learning to use them in a different way, Knipfer said."

The Precision Agriculture Revolution

The Precision Agriculture Revolution | Geography Education | Scoop.it

"Thousands of years ago, agriculture began as a highly site-specific activity. The first farmers were gardeners who nurtured individual plants, and they sought out the microclimates and patches of soil that favored those plants. But as farmers acquired scientific knowledge and mechanical expertise, they enlarged their plots, using standardized approaches—plowing the soil, spreading animal manure as fertilizer, rotating the crops from year to year—to boost crop yields. Over the years, they developed better methods of preparing the soil and protecting plants from insects and, eventually, machines to reduce the labor required. Starting in the nineteenth century, scientists invented chemical pesticides and used newly discovered genetic principles to select for more productive plants. Even though these methods maximized overall productivity, they led some areas within fields to underperform. Nonetheless, yields rose to once-unimaginable levels: for some crops, they increased tenfold from the nineteenth century to the present.  

Today, however, the trend toward ever more uniform practices is starting to reverse, thanks to what is known as 'precision agriculture.' Taking advantage of information technology, farmers can now collect precise data about their fields and use that knowledge to customize how they cultivate each square foot."

Our world has evolved and changed many ways in agriculture than it used to be. We've changed from horses pulling plows to using tractors with mowers on the back. Planting seeds by hand one at a time to using machines that can plant ten at a time five times faster. Watering plants one at a time to using water hoses. Our generation has advanced in farming technology and is helping our agricultural community. LDC

Giant Concrete Arrows Across America

Giant Concrete Arrows Across America | Geography Education | Scoop.it
Every so often, a hiker or a backpacker will run across something puzzling: a ginormous concrete arrow, as much as seventy feet in length, just sitting in the middle of scrub-covered America. What are these giant arrows? Jeopardy champ Ken Jennings solves the mystery.
Seth Dixon's insight:

This is fascinating...just because a technology is old and outdated in modern society doesn't mean it wasn't ingenious.  The original mathematicians who calculated angles and distances study geometry so they could navigate and 'measure the Earth.' Before GPS, these giant arrows helped pilots navigate across the United States; they are part of the genealogical strands of navigational technology.   Mathematics can be incredibly spatial as well as geospatial.

Spatial Navigation Before GPS

Spatial Navigation Before GPS | Geography Education | Scoop.it

"Giant 70-foot concrete arrows that point your way across the country, left behind by a forgotten age of US mail delivery.  Long before the days of radio (and those convenient little smartphone applications), the US Postal service began a cross-country air mail service using army war surplus planes from World War I.  The federal government funded enormous concrete arrows to be built every 10 miles or so along established airmail routes they were each built alongside a 50 foot tall tower with a rotating gas-powered light. These airway beacons are said to have been visible from a distance of 10 miles high."

I love articles like this one where they talk about the collide of different times. This article speaks of huge concrete arrows which were left from 1930's air mail routes. sadly most of the towers that were paired with the arrows have been dismantled but still really cool that these directional arrows from the past can still be found almost 90 years later.

The Longitude Problem

The Longitude Problem | Geography Education | Scoop.it
Seth Dixon's insight:

Today we take it for granted that through GPS technology we can instantaneously determine our latitude and longitude.  This video documents how for centuries it was fairly easy to determine latitude at sea by measuring the height of the sun in the sky, but longitude (determined by the difference in time between local noon and the noon of a fixed point) could only be estimated.  The British Empire saw solving the "longitude problem" as the key to solidifying their economic dominance at sea and they established the Board of Longitude in this 18th century "race to the moon." Today the University of Cambridge has digitized the Board of Longitude's archives with a series of five shorter video clips.

I have tried geocaching and it really does make you use geospatial tools. You have to know exactly where you are in reference to a map, you have to know directions in which you must travel, and you know you have to reach a certain place. While a fun activity, it is also a great geographic learning tool.

unit 1 nature and perspectives of Geography 

This video relates to unit 1 because of its description of Geocaching, a vocab word of this unit, which is a high tech treasure hunting game where people use gps to find and identify little boxes that were hidden in the surroundings.

This relates to unit 1 because it is a defining example of globalization and helping a group of people come together in their environment. This is also an example of contagious diffusion because of the beginning spread of this invention, which spread rapidly and in an outward direction.

Bounces in GPS signals reveal snow depth

Bounces in GPS signals reveal snow depth | Geography Education | Scoop.it
UNAVCO, a non-profit university-governed consortium, facilitates geoscience research and education using geodesy.


"Researchers at the University of Colorado Boulder and the University Corporation for Atmospheric Research have been using what is typically considered an error in the GPS signal to measure snow depth around GPS receivers. A GPS receiver records both direct and reflected signals from a satellite. A reflected signal bounces off of whatever is around the GPS station before being recorded, and therefore can contain information about the ground surface close to the station.

Traditionally snow depth has been measured by hand. In other words, someone had to go out with a measuring stick to whatever location they were interested in.  GPS snow depth measurements solve both of these problems: once a GPS unit is installed, it can function on its own throughout the winter, and will make a measurement every two hours, which is then averaged for a daily position, or in this case, snow depth."

Twitter is something that is becoming widely used, and is something I usually check everyday. I never really thought of twitter beyond advertising and communicating. It is amazing the kind of data that can be extracted from peoples tweets. In the soda vs. pop argument I would say soda which makes sense since the data shows that people in the Northeast refer to it as soda. Twitter is so current that you can actually get some current and accurate data just from reading the hash tags in peoples tweets. It's amazing that such information can be extracted from all around the world.

This text tells about a geographer who exaggerates today's modern dependency of Global Positioning Systems and Mapping, and the importance of still developing a mental map. It is important because lack of reliance of our mental maps leads to a primal fear and increasing instances of the feeling of being lost. The challenge is presented of how we stimulate technology in our mental maps. 

 

This article describes technological and mental process of mapping and how we should use it in our everyday lives. This is important because it gives humans a sense of direction and tells us how to keep it.

GPS Astray: Lost in Death Valley

GPS Astray: Lost in Death Valley | Geography Education | Scoop.it

"Three women’s Death Valley day trip soured after their GPS led them to the edge of survival."

Seth Dixon's insight:

This is a extreme example, but this video serves as a cautionary tale.  The harsh and unforgiving physical geography of Death Valley does not tolerate a lack of preparation.  Here is part 2 of the video.  Garmin the GPS manufacturer's statement on these videos is quite telling "GPS's shouldn't be followed blindly...it is incumbent on users to obtain and update their GPS devices with the most recent map updates." 


Technology is designed to guide and assist our decision-making process--that does NOT mean we should turn over thinking functions to the device.  Spatial thinking is just like a muscle that will atrophy if it is never used.  So consult a map and think for yourself; newer technologies aren't always better or more reliable.

Mike Carney's curator insight, September 30, 2013 4:48 PM

GPS devices are very useful tools, but if you don't know how to use them properly they can be very frustrating and sometimes can get you into trouble. On the surface a GPS seems like a pretty fool-proof navigation device, but that's giving people way too much credit. A lot of (older) people can have a hard time following them. Take my mother-in-law for example, she once got lost for a half hour on the ten minute drive from my house to the highway. Somehow she missed the ONE turn and apparently didn't understand how to make a U-turn. People generally go astray if they fail to update their GPS, don't know how to configure their settings properly, or follow the GPS blindly. People often forget that they can just use the GPS as a map and figure out their own routes when the GPS is being wonky. Its also a good idea to keep real maps in your car so you don't have to rely soly on the GPS. The women from the video were dealing with a GPS that was following inaccurate and outdated information. At a time like this its a good idea to pull over and get out the map rather than drive in circles until you run out of gas.

 

Ana Cristina Gil's curator insight, October 12, 2013 3:43 PM

       Is not always the best idea to only rely on you GPS when traveling, best thing to do is to get and updated maps.  Is always good to get information on where you are going, how long are you going to be there? So you can get enough supplies like food, water, clothes etc.  Also are you making other stops along the road? Let someone know where you going therefore; if something happened to you they know where to look for you, once again don’t always trust on electronic. Prepared AHEAD!!

Justin McCullough's curator insight, December 12, 2013 1:21 PM

Although I have grown up around technology, I've always been a little skeptical about its reliability. It is a good thing to have a GPS, but we should not rely solely upon it. Relying solely upon technolgy is not as good as it sounds. In some cases the GPS could be wrong and in instances such as these we need to be able to think for ourselves. Not having this ability is a dangerous situation.

A billion people worldwide live in slums, largely invisible to city services and governments — but not to satellites.

The slum-mapping movement began in India almost a decade ago and migrated to africa, the idea of this is to make slums a reality to people who have never set foot in one before. The maps can be used in court to stop evictions or simply to raise awarance. I think this idea is on the right track of what needs to be done. These people need help and so many people incuding the governement pretend they arent their but with these maps as proof they can no longer do that.    

Elizabeth Bitgood's curator insight, March 19, 2014 10:24 AM

Slums and squatter settlements are a problem that a lot of the developing world has to deal with.  The unsafe and unsanitary buildings cause headaches and problems for the leaders of the cities they surround.  This story is hopeful in that the city did manage to bring a water line out to get clean water to the people living in this area.  Perhaps this will lead to a better quality of life of the inhabitants of this particular slum.  Also the project of mapping such areas can be a useful tool for city planners to better regulate these areas and help the people that live there.,

Justin McCullough's curator insight, December 12, 2013 1:29 PM

While technology does has its pros it also comes with its cons. GPS batteries can die; the map on the screen may be unreadable due to size, the GPS itself could break if not handled properly. When it comes to maps, it is durable and legible in any position. However, I can not read a map while driving my car to a certain place. It is rather difficult to find a place when i'm in unfamiliar territory. In this case the GPS is able to direct me to where i need to be. If handled properly, the GPS is, at least in my opinion, better than the map. However, it is nice to keep and extra map in the glove compartment, just in case.

West Virginia aims to put its residents on the map
Seth Dixon's insight:

While this article does occasionally play off of the country bumpkin stereotypes we've all heard about West Virginians, there are some important concepts lying under the surface in the article.  All places have a location (both absolute and relative), but not one that is easily discernible to an outsider unfamiliar with the area.  Many emergency responders rely on geocoded addresses and GPS systems to location those in need, and the state of West Virginia is trying to ensure that even the most rural of residents is on the grid.  Many location-based technologies lose their value as soon as you leave a named road, so these systematic campaign will strengthen the push for modernization and digital systems.  How will this change the cultural landscape?

I ended up zooming out and looking at the map to know where the street was I was looking for. I then managed to find a route that lead around the bridge.

"Now that it is easy to gather tracks and waypoints on a smartphone and map them in a GIS, it provides a good opportunity to remind students about the importance of being critical of and paying attention to data.

I emailed the data to myself and added the GPX file to ArcGIS Online so I could map and examine the track.
