There are plenty of regional biases about other places. This map was generated by Google autocomplete. If you Google, "Why is Rhode Island so...." if will automatically suggest some responses. This was done for all the states and these autoresponses are quite revealing (and often humorous).
The National Atlas that is available online has an extensive database for simple online mapping. This is "GIS-light," an easy way to explore the spatial patterns within U.S. census data and other data sets. The lists all contain a wide variety of variables, making this a good way to get students to explore potential research topics. Thanks to the Connecticut Geographic Alliance coordinator for suggesting this link.
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 geospatial data with a wider audience.
I found these cartograms from an article in the Telegraph and was immediately impressed. The cartograms originated here and use data from the Global Rural-Urban Mapping Project as to create the int...
This series of cartograms shows some imbalanced populations (such as the pictured Australia) by highlighting countries that have established forward capitals. Question to ponder: Do forward capitals change the demographic regions of a country significantly enough to justify moving the capital?
This is a clip from the TV show West Wing (Season 2-Episode 16) where cartography plays a key role in the plot. In this episode the fictitious (but still on Facebook) group named "the Organization of Cartographers for Social Justice" is campaigning to have the President officially endorse the Gall-Peters Projection in schools and denounce the Mercator projection. The argument being that children will grow up thinking some places are not as important because they are minimized by the map projection. While a bit comical, the cartographic debate is quite informative even if it was designed to appear as though the issue was trivial.
Questions to Ponder: Why do map projections matter? Is one global map projection inherently better than the rest?
This link is a companion site to the book, "Mapping the Nation: History & Cartography in 19th Century America" by Susan Schulten. The author and publisher have made all of the images available digitally, and they are organized by chapter as well as chronologically. This a great resource to find some of the important maps that shaped America and help mold the manner in which we conceptualize America. Geography and history teachers alike will be able to draw on these materials. The chapters include:
The Graphic Foundations of American HistoryCapturing the Past Through MapsDisease, Expansion & Rise of Environmental MappingSlavery and the Origin of Statistical CartographyThe Cartographic Consolidating of America
