Projection Lessons in Maps

For many years, I have used the following map in my presentations. This map is a great example of proportional symbology and is of an interesting subject, especially when juxtaposed with modern oil trading.  Of course, the cartographic style is great too.  I hadn’t much thought of the cartographer or why the map was created until recently.….

The Mappy Goodness that is GIS Day in the Scholars’ Lab

Every November on the Wednesday of Geography Awareness Week the world celebrates GIS Day.  On that day in Charlottesville the geospatial community gathers in the Scholars’ Lab for mappy goodness. And cake. In 2010 we threw open the Scholars’ Lab doors for folks to present geospatial lightning talks.  We were impressed by the breadth of….

Prism, Images and Binaries

Several of us were recently asked to come up with sample texts to use for a simulated Prism experiment. As the token art historian of our group, I volunteered to find an example that included images as well as text. My initial efforts were spent imagining how I would use Prism as a teaching tool….

Life, Liberty, and the Pursuit of Mappiness

Mr. Jefferson ended his best-known sentence with “Life, Liberty and the pursuit of Happiness.”   The only thing missing was maps. In the Scholars’ Lab, we’re all about the spatial goodness.   Inspired by Kansas State University’s Seven Deadly Sins maps, we set about converting the qualities of life, liberty, and the pursuit of happiness into….

Putting American Community Survey Data to Work

This past week, I read an article that claims the number of people “getting around” by bicycle is steadily growing. The article references the American Community Survey (ACS) and the League of American Bicyclists (LAB). Considering I am a certified instructor from the LAB, I wanted to check the data for myself (and map it).

Smarter Paper Maps

It’s a quiz.  I’ll name the required skills, you name the profession.  Go. Identifying map projections and coordinate systems Interpreting map scale Understanding techniques of cartographic relief Interpolating latitude & longitude Calculating geographic extent rectangles Too easy?  Well the profession I’m describing is not Geographic Information Systems guru or Cartographer or Neogeographer.   In fact, my….

WMS vs. tilecaching

In our work on Neatline, we have made a deliberate choice to start by restraining our work to map-sources that are quickly and easily provided through WMS. This leaves out (for now) two popular sources of map imagery; Google Maps and Open Street Map. I’m going to explain why we made that choice, and why, when we do come to make these sources usable with Neatline, we will do so with great care and with an eye to scholarly method.
