A computer game wants you to map the world's cropland so farmers can get more out of each harvest.
NPR has recently highlighted Crop Capture; Crop Capture is a game that uses Google Earth imagery to crowd-source agricultural data. From a pedagogical standpoint, this is a great way to visually introduce students the variety of agricultural landscapes that can be found around the world. This is an example of what many refer to as citizen science games which provides an alternative rationale for playing the game.

Are you sure you want to delete this scoop?
These types of approaches to crowd sourcing are becoming bigger and bigger by the day it seems.
This is cool, there are many agricultural types and you can see It here. different land areas have different soil and chemicals in it which certain types of crops can benefit from. It is important to know these things.
In New Hampshire they are doing great work to make mapping data useful in the classroom. This site is one that they use to show how students can map locally relevant data from an online data set. CoCoRaHS (Community Collaborative Rain, Hail & Snow Network) is a crowd-sourced network that gathers North American precipitation data. The data (especially the total precipitation summary) can be easily copied into as spread sheet and saved as a CSV file (which can be uploaded to ArcGIS online).

"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."
This is fascinating...just because a technology is old and outdated in modern society doesn't mean it wasn't ingenious. The original mathmeticans who calcuated angles and distances study geometry so they could navigate and 'measure the Earth.' These giant arrows are but one of those links in the geneological strands of navigational technology. Mathematics can be incredibly spatial as well as geospatial.
Adesso sembra incredibile che si usasse un sistema simile per guidare la posta aerea. Forse a quei tempi sembrava normale.
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.
"Create a color-coded Visited States Map, showing off your road travel in the United States and Canada."
The map above represents where I have been (green) and where I have lived (orange). Super easy, anyone can use this site to create a PNG file that maps out North America (maximum of 5 colors, including white). For more on how to create your own, read here. Canada, Alaska and Hawaii can be included as well.
This is pretty flexible in that you can use 4 different colors to shade individual states.
create your own map is interesing because it allows you to visualize and share with others your own journey around the country in terms of residence and visits being in seperate colors. Compared to the size of the country I myself have only been to very few states. I have yet to go to Alaska, Hawaii, the Midwest parts, and much of the Western part of the country. I am convinced that extensive travel is something i will accomplish in the yeard ahead. For the professor himself he still has several more states to visit. It is propbable that he will visit many more in the years to come

Dr Sarah Parcak uses satellite technology to unearth Egypt's ancient settlements, pyramids and palaces lost in the sands of time.
The uses of geospatial technologies are NOT limited to studying geography, but it is the bedrock of many research projects that involve spatial thinking (as demonstrated in this TED talk). Geographic principles and geographers can be very important components of interdisciplinary research teams.

In Wonderland, Alice got a chance to perceive herself as small and as tall after eating and drinking magical food and drink that changed her perspective, and allowed her to perceive reality as something far more interesting than it was ordinarily. I can only imagine that these scientists that got the opportunity to study ancient buildings and cities from satellites were enthralled like Alice, and became enlightened as to things that a few hundred years ago never would have been able to comprehend. The idea of new perspectives brought about by spatial thinking and satellite imagery is relatively new, but opens up many possibilities like determining cluster patterns of cities and villages in order to find central areas of societies, and to assess irrigation and agriculture and proximity to areas of currently located water, or water from long ago. I gave this some thought and compared it to our society. There would be mills near water, large settlements in the capitols, and other identifying characteristics that would relate rather directly to historical peoples not all that different from ourselves. Satellites are like the Eat me Drink me refreshments in that we can draw more conclusions from factually obtained imagery from way up high away, and then we can speculate further based on that. Ancient civilizations appeal to me because I am interested in the origins of humans, which most certainly came from other planets (in my opinion.) I would hope that there would be some clues visible from the skies about origins and settlement locations from long ago to see where they (in my opinion) landed on this world.
Dr. Sarah Parcak is using satellite technology to try to unearth Egypts ancient settlements pyramids and palaces. The high resolution satellites has infrared and thermal capabilities and the laser wave lengths can penetrate the earths surface to pinpoint objects. This makes it easier to find hidden objects like tombs and faster then digging to find them and reduces the risk of damage.
I love the iconic opening of this video clip with the Indiana Jones movie clip which I actually saw at a drive in, yes I'm that old. Great how we can use technology to find these area that might have gone undiscovered. As a history guy the implications of using this technology in finding out about the pass is exciting with limitless possibilities.
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.

The recently revised Geography for Life standards have been aligned to show how geographic skills can be taught within the Common Core framework. The National Geographic Society, in cooperation with the National Council for Geographic Education and the Network of Alliances for Geographic Education created Connections to be that link (for grade specific Common Core/Geography resources click here).
So how is this to be done? This storymap shows ten great examples of maps that can be used as reading documents, one for each of the 10 ELA Reading Standards.

"Although 75% of the planet is a relatively unchanging ocean of blue, the remaining 25% of Earth's surface is a dynamic green. Data from the NASA/NOAA Suomi NPP satellite is able to detect these subtle differences in greenness. The resources on this page highlight our ever-changing planet, using highly detailed vegetation index data from the satellite, developed by scientists at NOAA. The darkest green areas are the lushest in vegetation, while the pale colors are sparse in vegetation cover either due to snow, drought, rock, or urban areas. Satellite data from April 2012 to April 2013 was used to generate these animations and images."
As displayed in this fabulous video, NOAA has produced in-depth information about the Earth's dynamic vegetation layers. This is a great example of how remote sensing data can enhance our understanding of the planet; additionally it is packaged in a very user-friendly format for a wide ranges of audiences. For great static images of this data layer, National Geographic has produced this great gallery.

"Recent news stories discussed why geography is important to an informed and engaged society. To those of us in the geospatial profession, basic geography education is an essential foundation to encouraging young people to enter the workforce in surveying, photogrammetry, GIS and other disciplines in our field."
While many in the geography education business bemoan student's lack of global awareness as a rationale for geography education, this is the key angle that I feel we should be pushing: the workforce. We currently are not producing enough students with geospatial skills in the United States to fill the jobs (one of the problems with geography being classified as a social science). Now that is a practical reason to support geography that non-geographers can understand.

The Esri Thematic Atlas is a configurable web application that uses a collection of intelligent web maps with text, graphics, and images to talk about our world.
ESRI is moving towards creating a dynamic, authorative, living digital atlas and empowering users to create their own. See this great political map of 2008 U.S. presidential election that is a part of the altas; it goes far beyond simple blue and red states. StoryMaps are also democratizing the mapping process.

"Many of us tend to think of Antarctica as a sheet of solid snow and ice. But, in contrast with its peer to the north, the southern pole's ice sheet lies atop a rocky continent. What are its features, its mountains and valleys, plains and coastlines?
A new dataset from the British Antarctic Survey provides the most detailed map ever of the bedrock below, information scientists hope will enable them to better model the affects of climate change on the ice, whose melting will have an impact on climate the world over."

"I'm used to rivers that know what they're doing."
Even though Chris Hadfield's time on the space station is over, his twitter stream can still be a great source of images displaying the physical and human landscapes (and if you needed any more evidence that he's the coolest astronaut ever, watch his parting video singing David Bowie's Space Oddity).
This incredible image clearly demonstrates the fluvial processes that have creating and this and will continue to reshape this landscape. Meander scars, oxbow lakes, channel cutoffs, floodplains and point bars are all here in this gorgeous teaching image.

Lol... the first words that went through my head were h--- (heck) yeah. David Bowie... sung by an astronaut... okay, back to Geography. I thought that the rivers reminded me of something I thought of during the talk in class about lava rock being changed into other kinds of rocks over time, and cycling around. I thought on a larger scale, about this universe, and I have read before that people are studying different areas of space-time fabrics, trying to find origins of the Universe, and answers to other existential questions. I suppose that if one could trace patterns of rivers, and if one could trace patterns of rocks, to find where they came from, and why/how they came where they came, then by examining the (assumedly tattered and marked) fabrics of space and time, people would be able to determine origins of everything from the beginning of what existed before all universes, and also the origins of life forms. I enjoyed the movie Prometheus, which was directed by Sir Ridley Scott, and I had to say that I thought that the messages found on rocks in caves, as a catalyst that lead the cast to go visit an alien world that had something to do with human origins, could be very literally taken. If there are clues in rocks, why wouldn't there be other clues, possibly in celluar components of life forms, or space and time? Applying the idea of studying rocks and rivers and other physical geographical pursuits to the idea of applying it on a gigantic scale greatly appeals to me. I believe that humans will find some answers that way, but I hadn't directly realized just that until we mentioned some stuff about physical geography, and glacial forces carrying and spreading out rocks, and deposits and erosion. After all, the Milky Way has origins, so why believe that we came from the Milky Way, rather than beyond?

Geospatial awarness and application is important GIS Day allows people to learn about and plug in to present technology that helps make geopraphy more palpable and easier to understand. There are more and more resources and advancements that have been made available to teach us and simply things in the world around us. understanding relatability and awareness helps us to answer questions about geography that we might not know because of distance and allows those who are preparing to be social studies or history majors to communicate to their students a better understanding of the world around them, and as time passes more helpful resources will be teaching aides in the classroom
Interesting, educational and new learning for some.
The Landsat Data Continuity Mission is now Landsat 8, and that means images are now public (woohoo!). NASA handed control of the satellite to the USGS earlier this year (May 30, 2013), and calibrated imagery is available through the Earth Explorer. Unfortunately, the Earth Explorer interface is a bit of a pain, so I’ve put together a guide to make it easier.
If you have been afraid to download remotely sensed images, this is a very-user friendly, step-by-step guide on how to download Landsat 8 data (and many other geospatial datasets) using Earth Explorer from USGS.

Looks like a cool tool for mapping activities.
The Landsat program is an essential tool for geographers when they are studying GIS. Without this data, Google Earth and many of the other mapping programs we love so much would not be possible.
Venice is sinking--no news there. Some of the sinking is natural based on the geomorphological processes on being in a lagoon and some is based on how people have modified the physical landscape. The GREEN on the map represents restoration efforts to stabilize the city while the RED indicates that human-caused activities have produced sinking. Additionally in this new study, researchers have used remote sensing data to differentiate between the anthropogenic sinking (human-caused sinking) and the natural sinking in Venice. This city is a perfect example of the three major types of human and environmental interactions [we 1) depend on the environment, 2) adapt to the environment and 3) modify the environment] and shows the issues associated with these interactions. Click here for a hi-res image of Venice and to see why I love the city.

This detailed account of the problems faced by the people, and city, of Venice is a great account of the idea of Human Environment Interaction that is central to Human Geography. Human actions are causing the city to sink while more human actions are attempting to raise the city out of the water.
It is no surprise to anyone that one day the beautiful city of Venice will one day be completely submerged under water. However looking at this map makes it hopeful that the process may be slowed down or even stopped! Looking at the map the green boxes represent the parts of Venice that have been uplifted, while the red boxes represent the parts that are sinking. What was surprising was that there appeared to be more green boxes on the map than red. Most of the boxes, both green and red, are along the coastline. I would think since most of the damage is along the coast line it would be a little easier to try and uplift. Hopefully the green boxes can make up for the red boxes in order to keep Venice from continually sinking. With these advances who knows where we will be in even another twenty years. We may be able to continue to uplift Venice to prevent it from submerging under water. It appears that the city is making progress in this process from the data given in the map.
As we all know Venice is known for its lack of streets because the city is navigated by canals. This map shows where humans are actually causing the city to sink (in red) and where through restoration and consideration are helping the city stay afloat (Green). These little acts of restoration can become increasinly important in the future with growing population density. Lets hope that Venice doesnt get to populated though so the next generation dosent have to refer to it as the lost underwater city of venice.
"Three women’s Death Valley day trip soured after their GPS led them to the edge of survival."
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.

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.
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!!
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.
Spring comes, then summer, fall and winter and if you are off the planet with a camera looking down at Earth, the seasons seem like breaths. Speed up the imagery, and the planet seems to pulse, like a living thing.

The Urban Observatory city comparison app enables you to explore the living fabric of great cities by browsing a variety of cities and themes.
Yesterday at the ESRI User Conference, the Urban Observatory was unveiled. 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.

Easy to find a picture of the city in the world.
I have been using Google Earth to check out a few different areas that I have and have not been to, particularly Washington D.C./Maryland, which I visited last month for the first time. I thought it was truly awesome and loved all the subtle differences as well as the larger and more obvious differences from RI. This Observatory is pretty interesting, and doesn't limit your observations to strictly visual perceptions, unlike most Astrological Observatories. It is a compendium of knowledge, information, and facts that define and characterize, categorize and redefine areas of the world. This seems like something out of Minority Report or Deja Vu (two really good sci-fi movies with visual observation technology that looks through time), both because of its appearance, and because of its general function. It also reminds me of some stuff that I've seen in the 1967 "The Prisoner" series, which really blew my mind about sociological portayals of the occasionally subversive human condition from entirely oppressing parties and circumstances. Hopefully this information will, as comes with great power, be treated with great responsibility... For all our sakes.
The best technologies aren't only the newest and the most expensive. We are often attracted to the latest and greatest and devalue the tried and true practices out there.

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.
Today was the first of the T3G Institute at the Esri headquarters and the wonderful team has shared great resources that I found incredibly useful for teachers to use great web maps. So what makes a great web map. A great web map should be highly interactive, intuitive, and be able to function at various scales. This video helps to show the power of maps to help tell a great story or to share spatial content.
The presenters each shared an exemplary web map.
