GigaPan Time Machine enables simultaneous exploration of space and time across massive datasets that could not previously be interactively explored at full spatial and temporal resolution.

GeoPlatform.gov/gulfresponse is a new online tool that provides you with near-real time information about the response effort. Developed by NOAA with the EPA, U.S. Coast Guard, and the Department of Interior, the site offers you a "one-stop shop" for spill response information. The site integrates the latest data the federal responders have about the oil spill's trajectory with fishery area closures, wildlife data and place-based Gulf Coast resources - such as pinpointed locations of oiled shoreline and current positions of deployed research ships - into one customizable interactive map.

Discourse Network Analyzer (DNA) is a Java-based application for qualitative category-based content analysis. It serves two purposes: coding statements of actors into categories, and converting these structured data into networks that are readable by UCINET, visone and other network-analytic software packages. The software can extract either bipartite (affiliation) networks or adjacency networks. It is complementary to semantic network analysis applications because it neither relies on algorithms for automatic text processing, nor does it focus on the internal meaning or mental representation of a single text or document. Instead, tags are applied to the text data by manual inspection, thus rendering it more flexible, yet at the same time more work-intensive. DNA can be used to code a large body of text documents and then convert them into graphs. The application is currently being developed, tested and heavily used in my dissertation research project on German pension politics. Updates will be posted here as soon as something has been published. If you use DNA, I would love to hear from you about your project (if possible, via the DNA-help mailing list). For more information about the software, please consult the documentation or obtain a free copy from the download page.

The JavaScript InfoVis Toolkit provides tools for creating Interactive Data Visualizations for the Web.

Working with network data

NodeXL data importer for social networks!

From basic statistics to machine learning and new ways to think about visualization, the Data Science Starter Kit gives you the tools you need to get started with data. If you haven't yet taken the leap, why wait? And if you're already experienced with data, the Starter Kit will push you further. The package includes (8) titles on R, basic statistics and data analysis, Python, machine learning, and visualization. This kit includes everything you need from analysis, visualization, to management.

SNA package used for "ordinary" data (one line of data for each case) and for network data (two files - "nodes" and "links" )

"How do you move from a culture of "need to know" to a culture of "need to share?" Richard Boly thinks about the answer to that question every day. Boly, a speaker at next week's Gov 2.0 Expo, is the director of the Office of eDiplomacy at the State Depar

Kovas Boguta, the head of analytics at Weebly and a guest author on ReadWriteWeb, has created another powerful data visualization, this time of the "the pro-democracy movement in Egypt and across the Middle East." The visualization drew from Twitter use by Egyptians and influential others around the #jan25 uprising. Those writing in Arabic only are represented in red, only in English are in blue and overlap by various shades of purple. Influence, in terms of follows, are represented by lines and those who influence each other are located in proximity.

NodeXL is an open-source template for Excel 2007 and 2010 which provides the utility to create a hierarchical network edge list. With NodeXL, you can create a customizable hierarchical network graph and zoom, scale, or pan it for a more refined look of added data. Networks can also be imported or exported to a variety of file formats. For example, you can create a graph displaying a company's chain of command and structure of subordinate employees. NodeXL provides the convenience of eluding difficult applications, arcane file formats and programming language for creating such graphs. You can even import a list of your Twitter followers or YouTube and Flickr connections, to create graphs representing your social network.

Cogito semantic technology The material analyzed through the intelligence process is mostly unstructured: communications, conversations, data, news, etc., and rarely has an organized form, such as a database structure. As a consequence, the activities of analysis and processing can be highly resource consuming, and prone to error. The work of analysts and knowledge workers remains essential, and technology cannot fully replace it (and never will). Nevertheless, with new generation software based on semantic analysis, it is now possible to understand data automatically as well as to support reasoning and stimulate intuition.

The advantage of NodeXL, particularly for graphing Twitter communities, is it has built-in features for grabbing the data for you. Not only that the coding is clever enough to handle the data collection for mere mortals, so when you hit your rate limit NodeXL waits until it should be able to get more data. NodeXL also has "built-in connections for getting networks from Flickr, YouTube, and your local email. Additional importers for Exchange Email, Facebook, and Hyperlink networks are available".

Luka Potkonjak has contributed a new feature to NodeXL: edge bundling.  Following on the heels of the release of curved edges in version. 175, we now provide a way to gather parallel edges together into "bundles" that travel together until they diverge close to their destinations.
