"Schools used to be the heart of a neighborhood or community. Children and not a few teachers could walk to class, or to the playground or ball field on the weekend. This was relatively easy to do, because the schools were placed within, not separated from, their neighborhoods. They were human-scaled and their architecture was not just utilitarian, but signaled their importance in the community. Now it has become hard to tell one from a Walmart or Target."
What better way to demonstrate the concepts of urban sprawl, automobile-dependent city planning and economies of scale than by analyzing the very geographic context of our schools themselves? This is a very nicely arranged photo essay that most could spark conversation and would foster some discussion on how best to plan neighborhoods and spatially arrange the city.
The natural landscapes shown as captured by satellite imagery is as beautiful as anything artists have ever created. Some of the colors shown in the video may seem otherworldy. Most of those color anomalies are due to the fact that remotely sensed images have more information in them than just what we see in the visible portion of the electromagnetic spectrum. Some of these images are processed to show different bands so we can visually interpret data such as what is in the near infra-red band, skewing the color palette.
The NDVI (Normalized Digital Vegetation Index) is on of the primary methods for detecting healthy vegetation using satellite imagery. This also serves as a useful way to distinguish between distinct ecological and agricultural regions and the temporal patterns of planting seasons.
In geography, the antipodes of any place on Earth is its antipodal point; that is, the region on the Earth's surface which is diametrically opposite t...
I know that most Americans have learned at an early age that if you dig a hole through the center of the Earth, you'll end up in China. Geologic and impossibilities aside, most Americans would actually end up in the Indian Ocean as displayed by this clever pairing up maps that shows the user the Antipode of any given place on Earth. Try it out! http://www.antipodemap.com/
Today's New York Times has a front page article on food deserts in the US by Gina Kolata (Studies Question the Pairing of Food Deserts and Obesity ). Food deserts are places that are believed to be lacking in healthy and affordable food.
The February 2012 ArcGIS Online update has just been released. This latest update includes additions and enhancements as described below, as well as a number of bug fixes and behind-the-scenes improvements.
This interactive map documents where 443 million people around the world get there water (although the United States data is by far the most extensive). Most people can't answer this question. A recent poll by The Nature Conservancy discoverd that 77% of Americans (not on private well water) don't know where their water comes from, they just drink it. This link has videos, infographics and suggestions to promote cleaner water. This is also a fabulous example of an embedded map using ArcGIS Online to share your geospatial data with a wider audience.

If you've never seen the Google Earth Blog, this post is a good primer to the educational possibilities that this technology opens up to teachers. It is not just for geography teachers; it can be a visualization tool for any subject that has real-world applications that take place somewhere.
Esri's GIS (geographic information systems) mapping software helps you understand and visualize data to make decisions based on the best information and analysis. (RT @Esri: #EsriUC--Where ideas are born!

"This picture shows the size of a sphere that would contain all of Earth's water in comparison to the size of the Earth. The blue sphere sitting on the United States, reaching from about Salt Lake City, Utah to Topeka, Kansas, has a diameter of about 860 miles (about 1,385 kilometers) , with a volume of about 332,500,000 cubic miles (1,386,000,000 cubic kilometers). The sphere includes all the water in the oceans, seas, ice caps, lakes and rivers as well as groundwater, atmospheric water, and even the water in you, your dog, and your tomato plant."
A colourful summer marine plankton bloom fills much of the Baltic Sea in this Envisat image. Plankton are microscopic marine plants that drift on or near the surface of the sea, by far the most abundant type of life found in the ocean.
