Not all is as it appears.

This article explains and talks about 18 specific map projections. It gives a lot of detail about all of them, and describes the disadvantages and uses for all of them.

I thought that this was interesting because I learned more about map projections, and actually how people use them.

This article chronicles 18 map projections, how they are mathematically rendered with their own unique set of advantages and disadvantages. 

Questions to Ponder:  Why do map projections matter?  Is one global map projection inherently better than the rest?  What is your favorite?

APHG-Unit 1

This video covers various topics important to mapping and satellite imagery (and alesson from an APHG teacher on how to use this video with other resources).  There is so much more to the world and space than what we can see see.  Chromoscope, referenced in the video, simulates other forms of energy on the electromagnetic spectrum besides just visible light.  This type of information is at the core of the science behind all of our satellite imagery.  This video also covers many map projection issues and highlights online resources to understand map distortion including:

No screenshot could do justice to this animation.  It transforms a map of the world from one map projection to another, and in the 5 second interval it 'spins the globe' to give you a sense of the the spatial distortions inherent in all projections.  This is but one of the many visualizations fromJason Davies mapping project.

Would an inverted Peters projection "freak you out"?

As part of geography education we are required to teach students about different map projections and the rationale for these. This little video puts it quite well.

helps show the different perspectives of our world and how it has changed. also shows many different forms of mapping our world throughout time.

UNIT 1 

This article discusses map projections and how they shape our perception of the world. Maps influence how we see the world, and could change the way we see it as well. These projections show us many different views of the Earth, which is very influential to our perspectives. This applies to unit 1 and its major concepts and underlying geographical perspective such as analyzing maps.
