This is great fun! A little tricky at first though:)

Great site to show projection and changes in perception on maps.

Where Does Your Water Come From?

Where Does Your Water Come From? | riavaluoS | ACCI SRL | Scoop.it

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 was definitely unaware of where my drinking water came from. This is nice, user-friendly map... Hopefully it gets updated regularly, as it will be interesting to see how these sources change over time.

water is a resource we all depend on. Some of my best studies were on local Chesapeake Bay issues.

The Human Head as a Mercator Projection

The Human Head as a Mercator Projection | riavaluoS | ACCI SRL | Scoop.it
Such an ordinary object, yet so disturbingly presented…...

 

While we accept spatial distortion as a given in geographic projections, it is striking how much it alters reality when the same distortion in applied to the human head...worth showing when discussion mapping and projections.

I thought this was a good visual to demonstrate how you cannot just take a global map and just flatten it. You do not get the same scale and accurate description of the globe. While it may show multiple of the land features, the land features get distorted.
Jesse Gauthier's comment, September 10, 2012 11:46 AM
Seeing a human face spread out this way makes me now realize that a 2-D map is not a real interpretation of the world. But at the same time this is more of a strange picture than when a globe is flattened out. I guess we are more used to seeing a globe flattened out.

Map distortion.......
