From Internet Scout :

Cartography 2.0

http://cartography2.org/

Professor Mark Harrower at the University of Wisconsin Madison's Department of Geography was frustrated with the "inability of traditional textbooks to keep pace with Web technologies." So he and his colleagues set out to create Cartography 2.0, which is a "free knowledge base and e-textbook for students and professionals interested in interactive and animated maps." First-time visitors might want to look over the "Purpose" section before diving into the separate "Chapters" of the book. All of the chapters can be found on the homepage, and they cover topics such as map animation, virtual globes, elements of design, and map interaction techniques. Each chapter contains descriptive essays, along with maps and diagrams that illustrate key principles. The "New Content" section on the homepage features the latest additions to the site, and overall this work is a model for educators who might be interested in crafting an engaging and dynamic online textbook.

How to Make a US County Thematic Map Using Free Tools
http://flowingdata.com/2009/11/12/how-to-make-a-us-county-thematic-map-using-free-tools/ 

Posted by Nathan / Nov 12, 2009 to FlowingData Code, Mapping / 5 comments

There are about a million ways to make a choropleth map. You know, the maps that color regions by some metric. The problem is that a lot of solutions require expensive software or have a high learning curve...or both. What if you just want a simple map without all the GIS stuff? In this post, I'll show you how to make a county-specific choropleth map using only free tools.

The Result

Here's what we're after. It's the most recent unemployment map from last week.

Unemployment in the United States

Step 0. System requirements

Just as a heads up, you'll need Python installed on your computer. Python comes pre-installed on the Mac. I'm not sure about Windows. If you're on Linux, well, I'm sure you're a big enough nerd to already be fluent in Python.

We're going to make good use of the Python library Beautiful Soup, so you'll need that too. It's a super easy, super useful HTML/XML parser that you should come to know and love.
