Scarcity  of  information  is  a  common  frustration  for  many  historians.  However,  for  researchers  of  twentieth-­ and  twenty-­first  century  history  the  opposite  problem  is ….

Mapping Crowd Sourced Bicycle Data

Background Charlottesville is not the easiest place to ride a bicycle.  There are obstacles beyond the narrowness of the streets.  Let’s take a look at a few of these. The above map shows the elevation around Charlottesville with dark green being the lowest areas and bright red being the highest.  The Charlottesville street system is….

Size Matters

In geography, size matters.  On maps, large always wins over small.  We’re human.  We’re wired to quickly spot patterns and make visual comparisons.  See Tufte, Edward. Picture a map of your own state.  How does it compare in size to the states next door, the largest states, the smallest, or Texas? I recently joined with…. Continue reading “Size Matters”.

Data visualizations: Learning d3.js

[cross-posted at] The SCI study on humanities graduate programs and career preparation is humming along, and while survey responses come in, I’ve been working on determining how best to translate the data into meaningful graphics. After a lot of experimenting, I think the winner is d3.js. Short for for Data-Driven Documents, D3 is Michael…. Continue reading “Data visualizations: Learning d3.js”.

Prism and Praxis Reflections

It’s been a whirlwind of a year, but we finally made it! We have a fully functional tool, we’ve fulfilled our goals from our charter, and we can all look back on everything we’ve learned this year and be astonished by how far we’ve come. Although I wasn’t an absolute newbie to the DH and…. Continue reading “Prism and Praxis Reflections”.

The users can then click on the categories at the right-hand side of the page to…. Continue reading “Seeing the Prism: We Have Visualizations!!”.

Let’s get visual.

I am aware of how ridiculous the title of this post is, but I’ll gloss it by saying that visualizations have been a hot button issue in our recent Praxis talks, and in my opinion, they’re by far the “sexiest” element of Prism. After all, the viz page is where the magic happens. That being…. Continue reading “Let’s get visual.”.

Mapping the Catalogue of Ships

I’m very pleased to share a guest post by UVa Classics professor Jenny Strauss Clay, describing a new project we’ve undertaken at the Scholars’ Lab. We’re excited not only at the opportunity to use GIS techniques to test Professor Clay’s theories about the relation of ancient geography to mnemonic devices and poetic form, but also….

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….
